Mineralogical and morphological factors affecting the ...

202115The separation of copper and arsenic has always been a major problem of the flotation beneficiation process, which is affected by the multiple factors: the chemical speciation and mineralogical structure of elements in slag as well as the processing conditions such as pH of the pulp, the concentration of agents and the number of additives, etc. Ma et al., 2016 Alter, 2005 Roy et al.,

Development and evaluation of an early removal

2010121In the first stage controlledpotential flotation is used to separate arsenic and copper minerals to produce a lowarsenic highcopper concentrate and a higharsenic lowcopper concentrate. In the second stage, the higharsenic concentrate is roasted at low temperature so that the arsenic is selectively fumed off into a lowvolume stream product leaving a calcine rich in copper and sulphur.

Arsenic release through refractory gold ore processing ...

202141Ore beneficiation Flotation is the most widely applied process for the enrichment of Au refractory ores. Flotation residues are usually accumulated in tailing ponds or deposited in abandoned openpit and ground, underground mines.

The beneficiation process generates highvolume waste called tailings, the residue of an ore that remains after it has been milled and the desired metals have been extracted e.g., with cyanide gold or sulfuric acid copper. If a mining project involves the extraction of a few

Arsenic Immobilization by Calcium Arsenate

1999916Lime additions to arseniccontaining wastes have been proven to be beneficial in reducing the mobility of dissolved arsenic, presumably through the formation of lowsolubility calcium arsenates. However, the role of calcium arsenate formation in reducing the concentrations of dissolved arsenic has not been well established. Therefore, slurries with varying Ca/As ratios were equilibrated, and ...
