The main process for copper ore is flotation , for refractory mixed copper ore and refractory oxide ore , normally use hydrometallurgy process .It is a high technological enterprise that integrated research , manufacture, sales and service .
Developments in flotation reagents have made the recovery of a wide variety of oxide, carbonate and silicate minerals by flotation a more much effective and economic process. SGS is the most experienced and trusted organization in
Copper oxide ores Copper sulphide ores Flotation collectors Mineral processing Alkyl hydroxamates abstract Sherwood Coppers Minto Mine processes a high grade coppergold deposit in Yukon, Canada. The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides.
The variability of the Kansanshi mixed ore in terms of total copper and acid soluble copper grades has a major impact on the flotation recovery. In March 2011, three Blue Cube MQi (inline mineral quantifier) analysers were installed on the mixed ore flotation feed, concentrate and final tails respectively.
