copper arsenic flotation selectivity

Copper ions (if they are present in flotation pulp) activate the flotation of arsenopyrite, lowering the amount of xanthate needed for flotation [3, 5, 8]. The aim of the experimental testing, the results of which are presented in this paper, was to obtain rough lead concen- trate with the low content of arsenic…

The arsenic content of Rosebery copper flotation feed is mainly present as arsenopyrite (FeAsS), containing approximately 46.0% arsenic with the remainder of the arsenic in copper sulphosalts (tennantite (Cu 12 As 4 S 13)), in a solid solution series with tetrahedrite (Cu 12 Sb 4 S 13). Tennantite contains approximately 20.3% arsenic.

Selective Flotation - Mineral Processing & Metallurgy

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective ...
