Keywords: enargite, chalcopyrite, arsenic, flotation, copper resource. 1. Introduction. In the mineral industry, many copper and iron sulfide ores such as covellite (CuS), chalcocite (Cu2S), chalcopyrite. (CuFeS2) and pyrite (FeS2), contain arsenic (As) and antimony (Sb) bearing minerals such as enargite.

The removal of Cd(II), Pb(II), Hg(II), Sn(II), Sn(IV), Sb(III), Sb(V), As(III), and As(V) from aqueous solutions by colloid precipitate flotation using sodium sulfide as the coagulent and oleic acid (HOL) as the surfactant has been investigated. The complete flotation (about ) of these elements was attained at.

Arsenic and Antimony Removal from Copper Concentrates by .

Abstract. Copper concentrates with high arsenic contents must be pretreated before conventional smelting to prevent environmental pollution with arsenic compounds. In this work, experimental results concerning the selective removal of arsenic and antimony from copper concentrates are presented. The process consists of.

mill and flotation plant and then exported by rail. Considering the beneficiation facilities, remains found on place clearly indicate that flotation process was used. Antimony and arsenic minerals were concentrated by flotation process while generated wastes, known as tailings, were disposed in dry form on the pile created.

Antimony Recovery from End-of-Life Products and Industrial Process .

[38] investigated the concentration and isolation of antimony and arsenic in Sb-As-bearing gold ores by flotation. They demonstrated the flotation separa- tion of antimonite and arsenopyrite into separate products, thus increasing process efficiency and profit by improving the gold recovery rate and reducing the consumption.

Antimony - Wikipedia

When slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic. A rare explosive form of antimony can be formed from the electrolysis of antimony trichloride. When scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic.
