Supergene (geology) - WikiMili, The Free .

Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering. The descending meteoric waters oxidize the primary (hypogene) sulfide ore minerals and redistribute the metallic ore elements. Supergene enrichment occurs at the base of the oxidized portion of an ore deposit.

Of the three flotation circuits, the sulphide circuit has the highest recovery (>90%) due to the simple copper mineralization, with approximately 90% of the copper occurring in chalcopyrite. In the mixed ore, chalcopyrite hosts approximately 35% of the copper in the feed, and in the oxide ore this proportion is normally less than 20%.

Sulfide Ores - an overview | ScienceDirect Topics

Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic). Typical Cu sulfide recoveries to concentrate are 85–90%. Typical concentrate grades are 30% Cu ...
