Introduction of Copper Ore Dressing Process Xinhai

The common copper ore dressing processes are divided into flotation process and wet-process copper extraction process. According to mineral separation sequence, flotation process can be divided into differential floatation, bulk flotation, flotability ranking flotation, part-selective flotation, etc.

Selective flocculation of fines Columbia University

The basic principles of selective flocculation are actually similar to those of the conventional selective flotation process. First, the individual mineral parti-cles need to be liberated and dispersed, then a reagent is required that can selectively adsorb onto one or sev-eral of the mineral surfaces.

EXTRACTING METALS FROM SULFIDE ORES

Silver, gold and platinum group metals present in copper ores follow the copper in both the flotation circuit and the smelter, and are recovered in the final, electrorefining stage. Electrorefining is discussed in the final Section. Flotation is also used to split copper and nickel sulfides and separate them from iron sulfides and gangue minerals.
