Evaluation of sodium isobutyl xanthate as a collector in the …
The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 µm was froth-floated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t dosages. The concentrates and tails were dried …
Copper (Cu)
Concentration: Through flotation, the ground ore is mixed with water to form a slurry, where copper minerals attach to bubbles and are skimmed off as a froth, concentrating the copper content. Smelting : The concentrate is smelted to produce matte copper (a mixture of copper, iron sulfides).
