Characterization and Flotation of Sulfur from Chalcopyrite

Preliminary tests show that pine oil and kerosene are effective frother and collector, respectively. The effect of kerosene with 20 g/t pine oil at pH 6 is given in Table I. A kerosene dosage of 20 g/t gives a high sulfur recovery of 94%. However, the high grade of iliceous material in the sulfur flotation concentrate dilutes the sulfur grade.s

Refractory Gold Mining SGS

The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives.

Preg-robbing phenomena in the cyanidation of sulphide gold

Nov 01, 2000· 1. Introduction. Preg-robbing is the phenomenon whereby the gold cyanide complex, Au(CN) 2 −, is removed from solution by the constituents of the ore.The preg-robbing components may be the carbonaceous matter present in the ore, such as wood chips, organic carbon, or other impurities, such as elemental carbon.
