Advantages • Simplicity Disadvantages • Labour intensive Gravity Separation: Sluicing • Water is channelled to flow through a sluice-box. • Sluice-box is essentially a man-made channel with riffles (barriers) at the bottom. • Riffles create dead-zones in the water current which allows gold to drop out of suspension. Sluicing and panning results in the direct recovery of small gold nuggets and flakes. Gold Parting: Salt Cementation Process • Invented to remove Ag from Au-Ag mixtures around 6th century BC. Mix: argentiferous gold foil, common salt, brick dust or burnt clay and urine in a sealed container.

The recovery of gold and iron from cyanide tailings was investigated with a combined direct reduction roasting and leaching process. The effects of reduction temperature, coal dosage and CaO dosage on gold enrichment into Au-Fe alloy (FexAu1−x) were studied in direct reduction roasting. Gold containing iron powders, i.e., Au-Fe alloy, had the gold grade of 8.23 g/t with a recovery of 97.46%. After separating gold and iron in iron powders with sulfuric acid leaching, ferrous sulfate in the leachate was crystallized to prepare FeSO4·7H2O with a yield of 222.42% to cyanide tailings. Gold enriched in acid-leaching residue with gold grade of 216.58 g/t was extracted into pregnant solution. The total gold recovery of the whole process reached as high as 94.23%. The tailings generated in the magnetic separation of roasted products, with a yield of 51.33% to cyanide tailings, had no toxic cyanide any more.

  • Subpart L – Fluorinated Gas Production
    Mandatory Greenhouse Gas Reporting Rule: EPA's Response to Public Comments Subpart L – Fluorinated Gas Production Subpart L – Fluorinated Gas Production U.S. Environmental Protection Agency Office of Atmospheric Programs Climate Change Division Washington, D.C. FOREWORD This document provides responses to public comments on the U.S. Environmental Protection Agency’s (EPA’s) Proposed Mandatory Greenhouse Gas Reporting Rule: Additional Sources of Fluorinated GHGs: Subpart L, Fluorinated Gas Production. EPA published a Notice of Proposed Rulemaking in the Federal Register (FR) on April 12, 2010 (75 FR 18652). EPA received comments on this proposed rule via mail, e-mail, and at a public hearing held in Washington D.C. on April 20, 2010. Copies of all comments submitted are available at the EPA Docket Center Public Reading Room. Comments letters and transcripts of the public hearings are also available electronically through http://www.regulations.gov by searching Docket ID EPA-HQ-OAR-2009-0927. EPA prepared this document in multiple sections, with each section focusing on a different broad category of comments on the rule. EPA’s responses to comments are generally provided immediately following each comment. In some cases, EPA provided responses to specific comments or groups of similar comments in the preamble to the final rulemaking. Rather than repeating those responses in this document, EPA has referenced the preamble. Comments were assigned to specific section of this document based on an assessment of the principal subject of the comment; however, some comments inevitably overlap multiple subject areas. For this reason, EPA encourages the public to read the other sections of this document relevant to their interests.

  • Simulation Study of the Optimal Distribution of Cyanide in a Gold Leaching Circuit
    Minerals Engineering 19 (2006) 1319–1327 This article is also available online at: www.elsevier.com/locate/mineng Simulation study of the optimal distribution of cyanide in a gold leaching circuit L.R.P. de Andrade Lima a,b,*, D. Hodouin a a Department of Mining, Metallurgical, and Materials Engineering, Laval University, Quebec City, Canada G1K 7P4 b Department of Materials Science and Technology, Federal University of Bahia, C.P. 6974, Salvador, BA 40810-971, Brazil Received 25 September 2005; accepted 1 December 2005 Available online 19 January 2006 Abstract The mineral industry has been using cyanidation to recover gold from ores for more than a century; however, a systematic study of the best reactant addition strategy in a cascade of agitated leaching tanks is not available in the open literature. A phenomenological math- ematical model of the gold cyanidation process, calibrated with a set of industrial data from an Australian plant, together with an eco- nomic performance index is used to analyze this problem. The simulated results show that the best compromise between the two antagonistic effects, cyanide consumption and gold recovery, which are both function of cyanide concentrations, leads to a reagent dis- tribution that depends on the leaching and cyanide consumption kinetics, pulp feed characteristics, and economic factors such as the gold market value. For the specific studied plant, in the operating range of low cyanide consumption and fast gold dissolution, all the cyanide must be added in the first tank; however, in the operating conditions of high cyanide consumption, cyanide has to be distributed in the first, second and third tanks.

  • Myths and Realities in Artisanal Gold Mining Mercury Contamination
    MYTHS AND REALITIES IN ARTISANAL GOLD MINING MERCURY CONTAMINATION by GUSTAVO ANGELOCI SANTOS A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in THE FACULTY OF GRADUATE STUDIES (Mining Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) April 2013 © Gustavo Angeloci Santos 2013 ABSTRACT The world faces a major gold rush currently. Worldwide 15 million people work directly in artisanal gold mining in more than 55 countries. The usual method of extraction is amalgamation and cyanidation, or very commonly a combination of both. Significant amounts of contaminants are released to rivers and soil, generating environmental and health concerns. The majority of artisanal miners are involved in micro-mining, but it is believed that the majority of contamination comes from small to large artisanal operations. Larger operations involve less people, but process much more material, re- leasing much more contaminants as well. The present work explains how contamination is generated, through a com- prehensive analysis of the labor division in small-scale mining sites around the world, and also analyses aspects of different intervention approaches. Different approaches are taken by different groups working on the problem around the world. This work evaluates the most common kinds of interven- tion, with special attention to technical and legal aspects in trying to elimi- nate mercury use in gold extraction. The study is conducted by comparing different interventions strategies to evaluate the myths and realities from an engineering perspective. Special attention is paid to the evaluation of alterna- tives to amalgamation process for gold such as intensive cyanidation, borax direct smelting and chlorination.

  • Cyanide and Cyanide Complexes in the Gold
    CYANIDE AND CYANIDE COMPLEXES IN THE GOLD- MINE POLLUTED LAND IN THE EAST AND CENTRAL RAND GOLDFIELDS, SOUTH AFRICA. Elysee Bakatula Nsimba (0700692R) A dissertation submitted to the faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2009 CHAPTER ONE ─ INTRODUCTION 1.1 The history of mining on the Witwatersrand Basin The metropolis of Johannesburg, South Africa’s largest city and financial centre, owes its origin to the gold-bearing rocks of the Witwatersrand Basin (Figure 1.1). The basin-roughly oval in shape, approximately 350 km north east to south west direction and stretching over 150 km across-host seven major goldfields. Figure 1.1 The Witwatersrand basin (Viljoen and Reimold, 1999) 1 The gold-bearing conglomerate mined in the Witwatersrand Basin has a typical mineralogical composition of (Feather and Koen, 1975): • Quartz (70-90%); • Phyllosilicates (10-30%), consisting mainly of sericite, KAl 2(AlSi 3O10 )(OH) 2; • Accessory and minor minerals (1-5%). Some 70 different ore minerals have been identified in the conglomerates, the most abundant of which, after pyrite, are uranite (UO 2), brannerite (UTi 2O6), arsenopyrite (FeAsS), cobaltite (CoAsS), galena (PbS), pyrrhotite (FeS), gerdofite (NiAsS) and chromite (FeCr 2O4). Amalgamation Amalgamation was the principal gold recovery method used in South African gold mines at the start of mining in 1886. Crude amalgamation is still practiced by some artisanal gold miners in South Africa, mainly in the Mpumalanga Province. Unfortunately the method is in widespread use in some African countries (Sudan, Tanzania, D.R.
