BENEFICIATION OF ARSENIC BEARING COMPLEX

2012-10-4 · Beneficiation of arsenic bearing complex sulphide ore by flotation 205 (Cu 12 As 4 S 13), chalcopyrite (CuFeS 2), cerussite (PbCO 3), anglesite (PbSO 4) and smith-sonite (ZnCO 3). On the other hand pyrite, hematite, goethite, limonite, calcite and quartz were determined as gangue minerals. Figure 1 shows the mineralogical struc-ture of the ore ...

Mineral Processing - an overview | ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Arsenic removal from copper ores and concentrates

Abstract Removal of arsenic impurity in ores and concentrates containing copper (Cu) through alkaline leaching in NaHS media was investigated in this work. Samples containing Cu from 10 to 40 wt.% and arsenic from 0.8 to 14 wt.% with enargite (Cu 3 AsS 4 ) as main arsenic bearing mineral were used as starting materials and all leaching tests were conducted at 80 °C under normal atmospheric ...

2021-7-6 · Often ores (e.g., gold-containing ores) contain arsenic which is released into the environment as a consequence of the ore-beneficiation process or through leaching from waste rock material (Bissen and Frimmel, 2003; Nordstrom, 2011). Removal of arsenic is necessary before mining-affected waters can be safely discharged into receiving water bodies.
