How to Recover Ultra-Fine Particles
How to Recover Ultra-Fine Particles 1. BACKGROUND There is no controversy around the fact that mineral processing keeps getting harder and harder. Mineral deposits are getting more challenging and complex as mining companies are forced to bring new, low quality mines into production and try to squeeze as much as they can out of the long- neglected nether regions of existing ore bodies. Increasingly there is also a mandate to get more out of each tonne of ore processed and the focus often falls on fine (-75 micron) and ultra-fine (-38 micron) particles that historically might have been sent straight to the tailings dam. Why send these particles straight to the tailings dam? There are several problems that fine and ultra- fine particles can cause depending on the process. In gold leaching operations they can cause carbon fouling or interfere with Merrill-Crowe. Fines are notorious for being difficult to selectively float as well as degrading the selective flotation of coarser particles when they are intermixed. Filtration capacity is dramatically decreased when fines are present. With the exception of cyanide leaching for gold, fine and ultra-fines have traditionally proven to be very difficult to selectively recovery. Combining the process issues with challenges in selective recovery, many mines simply make the decision to remove the fines early in the process and send them straight to tailings. In fact, we have seen tin, tungsten and tantalum mines reject more than 10% of the target mineral in slime reject streams. ide Recovery (%) Recovery ide ph l Su Particle Size (microns) Figure 1: Sulphide flotation on 2 different ores (Feng & Aldrich, 1999) 2. -
Gravity Concentration in Artisanal Gold Mining
minerals Review Gravity Concentration in Artisanal Gold Mining Marcello M. Veiga * and Aaron J. Gunson Norman B. Keevil Institute of Mining Engineering, University of British Columbia, Vancouver, BC V6T 1Z4, Canada; [email protected] * Correspondence: [email protected] Received: 21 September 2020; Accepted: 13 November 2020; Published: 18 November 2020 Abstract: Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter method has been causing large losses of mercury to the environment and the most relevant world’s mercury pollution. For years, international agencies and researchers have been promoting gravity concentration methods as a way to eventually avoid the use of mercury or to reduce the mass of material to be amalgamated. This article reviews typical gravity concentration methods used by artisanal miners in developing countries, based on numerous field trips of the authors to more than 35 countries where artisanal gold mining is common. Keywords: artisanal mining; gold; gravity concentration 1. Introduction Worldwide, there are more than 43 million micro, small, medium, and large artisanal miners extracting at least 30 different minerals in rural regions of developing countries (IGF, 2017) [1]. Approximately 20 million people in more than 70 countries are directly involved in artisanal gold mining (AGM), with an estimated gold production between 380 and 450 tonnes per annum (tpa) (Seccatore et al., 2014 [2], Thomas et al., 2019 [3], Stocklin-Weinberg et al., 2019 [4], UNEP, 2020 [5]). -

Wabun Tribal Council
Wabun Tribal Council Context The Wabun Tribal Council (WTC), a non-profit regional Lead: Community (Ont.) council established in 1989 and based in Timmins, Steps of the Mineral Development Sequence: Ontario, is the regional representative body for the Pre-exploration, exploration, development, operation First Nations of Brunswick House, Chapleau Ojibwe, Key Finding: As a community-driven organization, the Flying Post, Matachewan, Mattagami, and Beaverhouse. WTC has helped facilitate engagement with exploration These communities are situated within the northeastern and mining companies and enhanced community readiness Ontario districts of Sudbury, Timiskaming, and by building capacity and maximizing local benefits from mineral resource development activities happening on Cochrane, all of which lie within the Nishnawbe-Aski its territory. Nation. The WTC’s Board of Directors comprises the Chiefs of the six communities. The WTC has an Executive Director and staff that work in the fields of health, education, economic development, and resource development. The WTC has played an important role in the development trajectory of the Wabun First Nations over the past decade, especially in the realm of mineral exploration and development. WTC staff are responsible for negotiating mining development agreements in collaboration with community leaders and acting as a point of contact for project proponents and as a liaison in communications between government, industry, and the communities. The WTC also provides each member community with the support of the other member First Nations. Description of Measures Implemented The WTC started with the mapping of traditional territories in preparation for mining. Through the mapping process, the Chiefs established “economic boundaries,” recognizing that traditional territories overlap, but that a basis for allocating revenues from Impact and Benefit Agreements (IBA) was needed. -

Received: 15 June 2019; Accepted: 17 July 2019; Published: 19 July 2019 Abstract: Scheelite (CaWO4) is one of the main raw material for the production of tungsten. It is usually encountered in skarn deposits where it is commonly associated with other calcium minerals as fluorite, apatite, and calcium silicates. Worldwide, scheelite is upgraded to the chemical grades by direct flotation, but the separation efficiency remains limited due to similar flotation behaviors of scheelite and gangue minerals with fatty acid. The only solutions used to overcome this issue involve high energy consumption or ecotoxic reagents. In the present study, a novel method based on the use of a centrifugal Falcon concentrator was investigated to perform an efficient elimination of gangue minerals and fine particles as well as an acceptable scheelite recovery enabling a decrease of the flotation reagents consumption. The performances of the two types of laboratory Falcon bowls, Falcon UltraFine (UF) and Falcon Semi-Batch (SB), were modeled using the design of experiments (DoE) methodology, which allowed to determine the best operating parameters for each bowl. -

Dense Media Separation – a Valuable Process for Preconcentration
1 Dense Media Separation – a Valuable Process for Preconcentration M Lundt1, I Grewal 2 1. Senior Process Engineer, Sepro Mineral Systems, 101A – 9850 – 201 Street, Langley, British Columbia, Canada V1M 4A3, [email protected] 2. President, Met-Solve Laboratories Inc. 101B – 9850 – 201 Street, Langley, British Columbia, Canada V1M 4A3, [email protected] ABSTRACT Dense medium separation (DMS) is one of several preconcentration methods used for early waste rejection from run-of-mine ores at relatively coarse particle sizes prior to additional milling and beneficiation. DMS has been used extensively in the coal, diamond, mineral sands, base metals and iron ore industries to produce either a final product or as a preconcentration step. Laboratory scale and pilot test work at the Met-Solve laboratory in Canada has demonstrated successful separation and upgrading of other minerals such as lead, zinc, copper and lithium based ores using DMS. This paper reviews historical dense media systems, results from the pilot-scale multi-stage DMS Separator “Condor” system, as well as production plants and associated laboratory heavy liquid separation (HLS) test work on various minerals. The mineral systems tested included a lithium bearing ore and a fluorspar ore. Other minerals were tested but are not reported in this paper. Pilot plant test work on a fluorspar ore showed that 41.6% of the mass could be rejected to the tailings stream while 95.3% of the CaF2 was recoverable to the product stream. On a spodumene sample that was tested, it was possible to reject 55% of the mass to tailings while recovering over 90% of the lithium. -
Annual Report 2017/18
ANNUAL REPORT 2017/18 Josias Fiddler, Luke Mamakeesic, Allen Meekis, Peter Fiddler, Peter Goodman of Sandy Lake staged a hunger strike in 1988 to protest years of poor health care for First Nations. DEDICATION REMEMBERING THE HUNGER STRIKE OF 1988 Sioux Lookout First Nations Health Authority (SLFNHA) dedicates this Annual Report to the five Sandy Lake First Nations men who on January 18, 1988 wound up improving healthcare for communities in Northwestern Ontario. A hunger strike at the Sioux Lookout Zone Hospital in Sioux Lookout was staged by members of Sandy Lake First Nation. They were the late Josias Fiddler, the late Luke Mamakeesic, the late Peter Goodman, along with the surviving members of the group; Peter Fiddler and Allen Meekis. The men were frustrated with what they described as “years of frustration, meaningless consultation, worsening health and deteriorating relations between Aboriginal communities and the Medical Services Branch (Health and Welfare Canada). Native leaders and the Federal Government negotiated an agreement and ended the fast on January 20, 1988. As a result, a three-member review panel was created that included Wally McKay, Dr. Harry Bain, and Archbishop Edward Scott. The three-person panel held its first formal meeting on March 17, 1988 and by May 1989 a 138-page report entitled From Here to There – Steps Along the Way” was released. The report outlined numerous issues/findings and made recommendations. By March 1989 Sioux Lookout Zone Chiefs made the recommendation to create an Aboriginal Health Authority, -

Conventional DMS is, however, limited to coarse particle sizes and is not practical when processing fines. To improve the separation efficiency when processing fine particles, centrifugal separators have been employed. This work investigated DMS in a lab centrifuge and a modified Falcon Concentrator, in order to process the slimes of a rare earth ore. It has been shown that centrifugal concentration using a dense medium is possible when recovering values from a slimes fraction. Both the lab centrifuge and modified Falcon Concentrator resulted in a similar performance. Keywords: Dense medium separation; Centrifugal separation; Falcon Concentrator; Fine particle separations 1 Marion et al. The Potential for Dense Medium Separation of Mineral Fines Using a Laboratory Falcon Concentrator 1 Introduction Dense medium separation (DMS) is a process by which particles are separated based on differences in specific gravity (SG). The process can be controlled with a high degree of precision over a wide range of separating densities and is commonly applied as a pre- concentration step for minerals (such as cassiterite) and in the separation of coal from contaminants (Wills and Finch, 2016).
