in mill feed. Their impact on final concentrate fluorine levels is entirely dependent on the flotation process response of each of these minerals, and is in essence the subject of this paper. The fluorine content of Ok Tedi copper concentrates varies typically from 250 • 900 ppm in concentrates that are sent to various smelter customers.
copper concentrate,copper ore,sulfide copper concentrate . Copper concentrate is the result of a flotation process after the copper ore has been mined and milled. Copper concentrate is an intermediate product used as raw material in the production of copper metal. Get Price
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
