Copper Smelter Updates II + Flash Smelting Sunday, August 18 Sunday, August 18 Official Opening & Plenaries ROOM: Ballroom AB 3:00 PM 3:30 PM - Presentation 616557 Title Pending Dale Andres, Teck Resources Limited 4:00 PM - Presentation 599003 Copper Market Drivers for the Short & Long Term Stephen Higgins, Freeport - McMoRan ABSTRACT The copper market is influenced by many factors, but it is mainly driven by the “fundamentals”, supply and demand. Supply has changed over time due to the economies of scale needed to produce copper from an ore body over the course of decades with declining grades. Historically demand has been closely correlated with growth in Industrial Production and electricity consumption. The superior attributes and cost effectiveness of copper will remain compelling over the short and long term. Mine development can take well over10 years from discovery to copper production. Hence, mine planning is a long-term investment with high capital costs. Over the short-term operating plans have to balance changing commodity prices that are highly volatile at times with managing steady production. Additionally, supply is increasingly scrutinized through responsible sourcing initiatives driven by end consumers, NGO’s and government regulators. Many of the drivers for demand such as construction, power utilities, and automobiles will remain drivers over the long term. Future applications such as electric vehicles, renewable energy, and energy efficiency will result in increased demand due to a 3 to 5 times multiple of copper intensity in those products. Other factors that influence the market primarily in the short-term include macroeconomic policy, trade, dollar valuation, and global availability. 1 Monday, August 19 Monday, August 19 Monday Teck Safety & Plenaries Ballroom AB 8:30 AM - Presentation 596602 The Kamoa-Kakula Project in the Democratic Republic of the Congo Steve Amos, Ivanhoe Mines SA (Pty) Ltd. ABSTRACT The Kamoa-Kakula Copper Project—a joint venture between Ivanhoe Mines, Zijin Mining Group Co., Ltd. and the Government of the Democratic Republic of Congo—has been independently ranked as the world's largest, undeveloped, high-grade copper discovery by international mining consultant Wood Mackenzie. It is a very large, near-surface stratiform copper deposit with adjacent prospective exploration areas within the Central African Copperbelt, approximately 25 km west of the town of Kolwezi and about 270 km west of the provincial capital of Lubumbashi in the Democratic Republic of Congo. A phased development approach is currently envisaged. The first phase of the project involves the development of a 6 Mtpa underground mine and surface processing complex (dual stream concentrator) at the Kakula Deposit (a discovery announced in early 2016) as the project’s first phase of development. The second phase of the project involves an integrated 12 Mtpa two-stage development, beginning with initial production from the Kakula Mine, to be followed by a subsequent, separate underground mining operation at the nearby Kansoko Mine, along with the construction of a smelter. 9:00 AM - Presentation 616559 Closing the Loop - Green Copper at Aurubis Thomas Bünger ABSTRACT Aurubis is the world's leading copper recycler, processing over 700,000 t of recycling materials per year. More than every third copper cathode at Aurubis is already made completely of recycled material. With mega trends like urbanization, industrialization and the globally growing middle class driving recycling volumes, both the quantity and the complexity of secondary raw materials will increase significantly. How will we meet the demands and expectations from our business partners and the society, and what is needed towards "sustainable copper" and other materials in the future - technically, politically and in terms of sustainability? In his Plenary address, Dr. Thomas Bünger, COO at Aurubis, will introduce the company's strategy towards "green copper" and beyond. 9:30 AM - Presentation 616556 Copper Price Outlook 2019-2020— Global Growth, Currencies & Commodity Prices Patricia Mohr, Scotiabank (retired) 2 Monday, August 19 ABSTRACT The outlook for copper prices in the context of expected global economic conditions (especially in China and Asia/Pacific), the impact of U.S./China trade relations, new sources of demand such as in electric vehicles, currency developments and investment in new mine supply. Will there be a shortage of copper in the 2021-23 period linked to limited new mine development? Copper 2019: Electrowinning & Electrorefining Electrorefining Operations I - Chair: Georges Houlachi Meeting Room 12 2:00 PM - Presentation 594940 Global Survey of Copper Electrorefining: 2019 World Tankhouse Operating Data Michael S. Moats, Missouri University of Science and Technology Andreas Filzwieser, METTOP GmbH Shijie Wang, Rio Tinto William G. Davenport, University of Arizona Tim Robinson, Outotec Andreas Siegmund, LanMetCon ABSTRACT This survey continues the long tradition of providing a snapshot of operating data from industrial electrorefineries. It is a supplement to previous surveys that were performed in 1987, 1991, 1995, 1999, 2001, 2003, 2007, 2010, 2013 and 2016. Analyses of current data and historical trends are presented. Examples of innovations to reduce costs, improve productivity, and improve quality are provided. In general, refineries continue to increase productivity while treating anodes with more impurities. 2:50 PM - Presentation 590965 'Permanent' Cathode Plate - Consumable or Fixed Asset? Addin Pranowo, Glencore Technology Nigel Aslin, Glencore Technology Graham Heferen, Glencore Technology Ola Eriksson, Glencore Technology ABSTRACT Glencore Technology (GT) has over four decades experience supplying stainless steel cathode plates (“cathode plates”) to the electro-refining and electro-winning industry. Cathode plates are typically the single biggest capital investment in a refinery. Refineries may view cathode plates as fixed asset or consumables depending on their operational characteristics. This paper examines the issue of cathode plate life and the strategies and philosophies used by different plants in the management of their cathode plate asset. Some plants operate with their original plates after more than 20 years. Others accept high turnover and regular maintenance as normal operating practice. Reference data are provided on plate life for various operating plants including benchmark plants achieving best-practice plate life and operating cost. The role of the 3 Monday, August 19 electrode handling equipment on cathode plate longevity is also examined, including latest developments in Cathode Stripping Machine, robotic copper stripping, and full-automation production cranes. The ability to identify and manage the population of plates in service is also critical for maximising plate life and minimising its overall operating cost. This paper discusses a novel and unique RFID system for tracking and managing cathode plate inventory 3:15 PM - Presentation 591294 Arsine Risk Management at Ccr’s Electrolyte Purification Plant Billy Serviere, Glencore Copper Canada - CCR Refinery Hans Persson, Glencore Copper Canada - CCR Refinery Arun Majumdar, Glencore Copper Canada - CCR Refinery ABSTRACT The CCR refinery, which was built in 1931, treats both internal and third party copper anodes to produce 325,000 mt of copper as cathodes. These anodes contain high levels of impurities, such as Ni, As, Sb and Bi, that reports to the electrolyte during the refining step and need to be removed in order to maintain cathode quality and operating efficiencies. In the purification plant, the electrolyte is decopperized via electrowinning in three stages. In the last stage, the copper content of the electrolyte is reduced to below 1 gpL in order to maximize the co-deposition of As, Sb and Bi with the Cu. This is accomplished with minimum arsine gas generation by using periodic reversal of the current and by controlling the final copper content of the electrolyte. Nevertheless, the possibility of exposure to arsine is treated as a major risk and controls have been implemented to reduce this risk. This paper describes the controls in place at the purification plant, which are being continuously improved through periodic risk assessments and audits. 150 years of Copper ER I - Chair: Mike Moats Meeting Room 12 4:05 PM - Presentation 605404 Origins of Electro-refining: Birth of the Technology and the World's First Commercial Electrorefinery Albert Wraith, Private Consultant Phillip Mackey, P.J.Mackey Technology Inc. Jennifer Protheroe-Jones, National Waterfront Museum ABSTRACT The world’s first copper electrorefinery started production in 1869 at Burry Port in South Wales. Built within the Pembrey Copper Works which had commenced smelting operations in 1849, the new refinery was based on principles described in the British patents 4 Monday, August 19 issued to J.B. Elkington in 1865 and 1869. Refining principles and practices pioneered there were key to the foundation of modern electro-refining practice in what is now a dominant international industry producing over 16 Mt of electrical grade copper annually. This paper explores the background to this pioneering application of the new, early 19th century, science of “electro-metallurgy” and examines its links to the contemporary decorative electro-plating industry and to the shortcomings of 19th century fire refining. The beginnings and early years of the Pembrey electrorefinery are briefly discussed in relation to the quality, applications

Received: 24 July 2018; Accepted: 13 August 2018; Published: 15 August 2018 Abstract: It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency. These complexities can be attributed to various reasons: Mg carbonates are naturally hydrophilic, soluble, and exhibit similar surface characteristics as their AVMs. This study presents a compilation of various parameters, including zeta potential, pH, particle size, reagents (collectors, depressant, and modifiers), and bio-flotation, which were examined in several investigations into separating Mg carbonates from their AVMs by froth flotation. Keywords: dolomite; magnesite; flotation; bio-flotation 1. Introduction Magnesium (Mg) carbonates (salt-type minerals) are typical gangue phases associated with several valuable minerals, and have complicated processing [1,2].

Depending on where the gold is found, this may be done by panning or through dry blowing. Each of these methods relies on the property of density. As gold has a very high density compared to the rock, soil and sediments it is contained in, it can be separated out by exploiting this property as it will fall to the bottom of mixtures that are allowed to settle out. The process of panning is used when small pieces of gold are found in creeks and rivers. It involves using a large shallow dish (pan) to scoop out some of the sediments in the riverbed and a small amount of water. You use a swirling motion with the pan tipped away from you and allow small amounts of the sediments and water to spill over the edge of the pan. When you have only a small amount of the sediments remaining in the pan, you will be able to see any gold particles that remain at the bottom of the pan. During the West Australian gold rush, most of the gold was being found in dry areas and water was a scarce commodity.

OF MET. & MATERIALS ENGINEERING, FEDERAL UNIV. OF TECHNOLOGY, AKURE, ONDO STATE, NIGERIA Email addresses: 1 [email protected], 2 [email protected], 3 [email protected], 4 [email protected] ABSTRACT The dire need for Itakpe iron ore concentrates of appreciable iron content meets for smelting operation necessitated this study. Core samples of the iron ore sourced from Itakpe, Kogi State, Nigeria were prepared for petrological analysis followed by chemical and particle size analyses. Froth flotation was done using different collectors at varying particle sizes and pH values. Characterization studies carried out revealed that Itakpe iron ore is a lean ore assaying 36.18% Fe2O3 and contains predominantly quartz, sillimanite, and haematite. Its liberation size lies favourably at 75 µm. Processing the ore by froth flotation yielded appreciable enrichment. Optimal recovery (~92%) was achieved using potassium amyl xanthate (PAX) at pH 11 for fine feed sizes (<125 µm) yielding iron concentrate assaying 67.66% Fe2O3. Thus, processing at this set-of- conditions is recommended for the industrial production of more enriched Itakpe iron ore concentrates.

  • Petrology of Ore Deposits
    Petrology of Ore Deposits An Introduction to Economic Geology Introductory Definitions Ore: a metalliferous mineral, or aggregate mixed with gangue that can me mined for a profit Gangue: associated minerals in ore deposit that have little or no value. Protore: initial non-economic concentration of metalliferous minerals that may be economic if altered by weathering (Supergene enrichment) or hydrothermal alteration Economic Considerations Grade: the concentration of a metal in an ore body is usually expressed as a weight % or ppm. The process of determining the grade is termed “assaying” Cut-off grade: after all economic and political considerations are weighed this is the lowest permissible grade that will mined. This may change over time. Example Economic Trends Economy of Scale As ore deposits are mined the high-grade zones are developed first leaving low-grade ores for the future with hopefully better technology Since mining proceeds to progressively lower grades the scale of mining increases because the amount of tonnage processed increases to remove the same amount of metal Outputs of 40,000 metric tons per day are not uncommon Near-surface open pit mines are inherently cheaper than underground mines Other factors important to mining costs include transportation, labor, power, equipment and taxation costs Classification of Ore bodies Proved ore: ore body is so thoroughly studied and understood that we can be certain of its geometry, average grade, tonnage yield, etc. Probable ore: ore body is somewhat delineated by surface mapping and some drilling. The geologists is reasonably sure of geometry and average grade. Possible Ore: outside exploration zones the geologist may speculate that the body extends some distance outside the probable zone but this is not supported by direct mapping or drilling.

No single model can explain all cases of corrosion nor can it explain all corrosion mechanisms of a particular refractory in different environments, but the knowledge of the microstructure combined with the chemistry of the systems are necessary to understand the corrosion mechanism of a refractory material.

  • Challenges Related to the Processing of Fines in the Recovery of Platinum Group Minerals (Pgms)
    minerals Review Challenges Related to the Processing of Fines in the Recovery of Platinum Group Minerals (PGMs) Kirsten C. Corin 1,* , Belinda J. McFadzean 1, Natalie J. Shackleton 2 and Cyril T. O’Connor 1 1 Centre for Minerals Research, Chemical Engineering Department, University of Cape Town, P Bag X3, Rondebosch, Cape Town 7700, South Africa; [email protected] (B.J.M.); [email protected] (C.T.O.) 2 Minerals Expertise Tech Pty Ltd., Germiston 2007, South Africa; [email protected] * Correspondence: [email protected] Abstract: In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve this, comminution circuits usually consist of two or three stages of milling, in which the first stage is autogeneous, followed by ball milling. Further liberation is achieved in subsequent stages using ultra-fine grinding. Each comminution stage is followed by flotation in the so-called MF2 or MF3 circuits. While this staged process increases overall recoveries, overgrinding may occur, hence creating problems associated with fine particle flotation. This paper presents an overview of the mineralogy of most of the more significant PGM ores processed in South Africa and the various technologies used in comminution circuits. The paper then summarises the methodology used in flotation circuits to optimise recovery Citation: Corin, K.C.; McFadzean, of fine particles in terms of the collectors, depressants, and frothers used.
