Review of the hydrometallurgy of chalcopyrite concentrates

Canadian Metallurgical Quarterly, 1972
AbstractA critical appraisal has been made of methods that have been proposed for the hydro metallurgical treatment of chalcopyrite concentrates. Those methods in which the primary breakdown of chalcopyrite is effected by leachants are discussed. Methods in which leaching is preceded by pyrometal-lurgical decomposition of the mineral include selective ...

Jarosites and Their Application in Hydrometallurgy

Reviews in Mineralogy and Geochemistry, 2000
The alunite supergroup consists of more than 40 minerals with the general formula DG 3( T O4)2(OH,H2O)6, wherein D represents cations with a coordination number greater or equal to 9, and G and T represent sites with octahedral and tetrahedral coordination, respectively (Smith et al. 1998). The supergroup is commonly subdivided into various groups, but

Emerging Technologies in Hydrometallurgy

Mineral Processing and Extractive Metallurgy Review, 1992
The need for mining industries to be sustainable requires them to maintain the balance between global competition and environmental responsibility. Depletion of available and easily mineable reserves offers opportunities to develop novel processes to treat complex or lower grade ores.

Some Recent Developments in Hydrometallurgy

Canadian Metallurgical Quarterly, 1984
AbstractThe objectives of hydro metallurgy are to extract metals; to purify and concentrate metal bearing solutions; to recover metals; and to render waste streams acceptable for disposal to repositories and the environment. These aspects are discussed by way of examples of plants and processes which have beerl used or developed recently.
