ARSENIC IN GOLD LEACHING

If arsenic is present, regardless of what form, solubility increases with higher pH. Environmentally; during or after detox, the arsenic can be precipitated via ferric sulphate leaching to produce the highly insoluble ferric arsenates which will settle, sometime requires the use of flocculant, in the tailings pond.

How to Obtain Arsenic | Sciencing

Obtain arsenic as a by-product of mining and refining other metals. Recover the flue dusts produced from copper, nickel and tin, which are high in the arsenides of these metals. Heat them in air to sublimate the arsenic and cool the gas to condense the arsenic back into a solid. This method accounts for most of the arsenic production in the world.

Copper-Arsenic Processing - Teck

The CESL Cu-As Process has achieved greater than 99% deportment of arsenic to leach residues (the by-product of the metallurgical process). Arsenic components in the residue have been identified, with the use of advanced mineralogical methods, as basic ferric arsenate (BFAS) and scorodite – both of which are considered the most stable forms for arsenic fixation.
