Arsenic trioxide is obtained as a byproduct from dusts and residues produced during the treatment of other metal ores such as gold and copper.  The arsenic trioxide can be purified on site or sold to a refinery.  China is the world''s leading producer of arsenic (25,000 tons in 2014) followed by Chile (10,000 tons) and Morocco (8,000 tons).
TREATMENT OF A COPPER- RICH GOLD ORE BY AMMONIA ASSISTED CYANIDE LEACHING . Figure 1. Particle size distribution of the ore . Mineralogical analysis (refer Figure 2) showed that the ore sample consisted predominantly of quartz. Chalcopyrite and Covelline were also identified to be present as the main copper minerals in the ore (refer Figure 2).
The treatment of copper–gold ores by ammonium . 2002-10-1 Ammonium thiosulfate is particularly attractive as an alternative to cyanide for the treatment of copper–gold ores. The presence of copper is desirable in a thiosulfate leach, whereas it is detrimental in a cyanide leach.
Treatment Of Copper Ores. Treatment of refractory gold ores springerlink oxidized copper ores are exhibiting increasingly their importance as copper resources as worldwide high grade copper sulfide deposits become depleted extensive chemical and technological efforts have been made to meet the demand of exploitation of.
Sulphide ore treatment process.the copper is liberated from the sulphide ore through a chemical processes called flotation.the resulting copper mixture is called concentrate, which is a grey-black powder that looks a bit like ash.it is roughly 30 copper, and may also contain traces of gold and silver.the copper concentrate then goes to.
