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]). -
On the Association of Palladium-Bearing Gold, Hematite and Gypsum in an Ouro Preto Nugget
473 The Canadian Mineralogist Vol. 41, pp. 473-478 (2003) ON THE ASSOCIATION OF PALLADIUM-BEARING GOLD, HEMATITE AND GYPSUM IN AN OURO PRETO NUGGET ALEXANDRE RAPHAEL CABRAL§ AND BERND LEHMANN Institut für Mineralogie und Mineralische Rohstoffe, Technische Universität Clausthal, Adolph-Roemer-Str. 2A, D-38678 Clausthal-Zellerfeld, Germany ROGERIO KWITKO-RIBEIRO§ Centro de Desenvolvimento Mineral, Companhia Vale do Rio Doce, Rodovia BR 262/km 296, Caixa Postal 09, 33030-970 Santa Luzia – MG, Brazil RICHARD D. JONES 1636 East Skyline Drive, Tucson, Arizona 85178, U.S.A. ORLANDO G. ROCHA FILHO Mina do Gongo Soco, Companhia Vale do Rio Doce, Fazenda Gongo Soco, Caixa Postal 22, 35970-000 Barão de Cocais – MG, Brazil ABSTRACT An ouro preto (black gold) nugget from Gongo Soco, Minas Gerais, Brazil, has a mineral assemblage of hematite and gypsum hosted by Pd-bearing gold. The hematite inclusion is microfractured and stretched. Scattered on the surface of the gold is a dark- colored material that consists partially of Pd–O with relics of palladium arsenide-antimonides, compositionally close to isomertieite and mertieite-II. The Pd–O coating has considerable amounts of Cu, Fe and Hg, and a variable metal:oxygen ratio, from O-deficient to oxide-like compounds. The existence of a hydrated Pd–O compound is suggested, and its dehydration or deoxygenation at low temperatures may account for the O-deficient Pd-rich species, interpreted as a transient phase toward native palladium. Although gypsum is a common mineral in the oxidized (supergene) zones of gold deposits, the hematite–gypsum- bearing palladian gold nugget was tectonically deformed under brittle conditions and appears to be of low-temperature hydrother- mal origin. -

The Geological Occurrence, Mineralogy, and Processing by Flotation of Platinum Group Minerals (Pgms) in South Africa and Russia
minerals Review The Geological Occurrence, Mineralogy, and Processing by Flotation of Platinum Group Minerals (PGMs) in South Africa and Russia Cyril O’Connor 1,* and Tatiana Alexandrova 2 1 Department of Chemical Engineering, Centre for Minerals Research, University of Cape Town, Cape Town 7701, South Africa 2 Department of Minerals Processing, St Petersburg Mining University, St Petersburg 199106, Russia; [email protected] * Correspondence: [email protected] Abstract: Russia and South Africa are the world’s leading producers of platinum group elements (PGEs). This places them in a unique position regarding the supply of these two key industrial commodities. The purpose of this paper is to provide a comparative high-level overview of aspects of the geological occurrence, mineralogy, and processing by flotation of the platinum group minerals (PGMs) found in each country. A summary of some of the major challenges faced in each country in terms of the concentration of the ores by flotation is presented alongside the opportunities that exist to increase the production of the respective metals. These include the more efficient recovery of minerals such as arsenides and tellurides, the management of siliceous gangue and chromite in the processing of these ores, and, especially in Russia, the development of novel processing routes to recover PGEs from relatively low grade ores occurring in dunites, black shale ores and in vanadium-iron-titanium-sulphide oxide formations.

SUCCESSION AND GOLD MINING AT MANSO-NKWANTA by Kwame Arhin* Introductory Manso-Nkwanta town lies hi miles south-west of Kumasi on approximately Latitude 6° 28' North and approximately Longitude I 59' West of Greenwich. The Manso-Nkwanta chlefdom Is a sub- unit of the Akwamu division (of which the head Is the chief of the Asafo quarter in Kumasi, the capital of Ashanti) of the Kumasi State. Manso-Nkwanta borders on Ashanti Bekwai in the West and on Sehwi Wiawso in the south-west. It is administered as part of the Bekwai district. I went to Manso-Nkwanta to investigate Ashanti tradition- al gold mining because information from both written and oral sources indicates that it was at least in the late 19th century a place of concentrated mining, Brandon Ktrby, a Special Commissioner of the Gold Coast travelling in Ashanti in 1884, records that the chiefdom was the first to revolt against the Ashantihene, Mensa Bonsu, because of its 'close proximity to the Protectorate /"Adansi .7 and also through gold mining, the principal industry, bringing large members of educated natives /"from the Gold Coast,/ amongst them'.' With regard to the oral sources of my information, an old informant at Ashanti Mampong who, in his youth had traded in gold dust for grey baft on the Gold Coast slaves, grey baft for slaves from Samory's war camp and slaves for rubber in the Ahafo district, north-west of Manso, stated that most of the Ashanti gold dust used in trade with the Europeans at Cape Coast and Saltpond was obtained through trade with miners at Manso-Nkwanta. -
