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.

 · Hunt teaches that the reducing gas may also be internally generated in the ore pulp itself by the action of one or more suitable chemicals. For example, when sulfuric acid and an alkaline (base) or alkaline earth sulfite, bisulfite, or thiosulfate are added to an ore pulp, sulfur dioxide will be one of the products resulting from the interaction.

copper flotation plant

Copper extraction - Wikipedia. Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.
