OneMine | Alteration of Chalcopyrite's Surface Chemistry …
ABSTRACT The sensitivity of sulphide minerals towards oxidation depends on the mineralogical makeup and nature of sulphide ores. This paper focuses on chalcopyrite behaviour in a nickel-copper sulphide- ore matrix that was aged in the mine-site stockpiles. Results of collectorless, collector-induced flotation and recovery by size are presented following a …

Uis Tin Mine Redevelopment Project, Erongo, Namibia
Uis tin project background. The Uis tin mine was discovered in 1911, while mining was commenced in 1923. The mine was expanded after Imcor Tin, a wholly-owned subsidiary of the Iron and Steel Corporation of South Africa (Iscor), assumed ownership in 1958. It became the world's biggest hard-rock tin mine in 1980.
