COPPER ORE

Basically sulphides are beneficiated by froth flotation technique using standard reagent like xanthate for flotation of copper sulphide minerals. The recovery of copper and the selectivity of separation are greatly influenced by the mineralogical characteristics of the ore and the various process parameters.

Innovations in Copper Mineral Processing Technology

Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: – Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill. – Manage ore blending programs more effectively.

60 Centuries of Copper: The Flotation Process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate ...
