Postregrind selective depression of pyrite in pyritic

Mar 01 2015 · The pyritic copper–gold ore used in this study was obtained from a copper–gold mine in Asia The pyrite rougher concentrate was obtained by twostage copper and pyrite rougher flotation using the conditions in Table 1 and reported in Agorhom et al 2013However in the present studies the focus is to examine flotation depression of pyrite after regrinding the combined pyrite rougher

Gold Ore Roasting Techniques Mineral Processing

With improvements in flotation methods the generally accepted procedure today is to concentrate the gold or silver bearing minerals into a small bulk and roast the concentrate only The calcine is then usually treated in a small cyanide circuit with the residues sometimes passing into the main cyanide circuit if the flow sheet includes such a step or sent directly to waste
