May 01, 2017 · It is well known that cyanide soluble copper dissolves in cyanide solutions to form toxic copper-cyanide complexes such as Cu(CN) 2 −, Cu(CN) 3 2 −, Cu(CN) 4 3 −.A number of studies have been published to treat gold-copper ores by either adding ammonia to the conventional cyanidation process, or recycling cyanide after the leaching stage (La Brooy et al., 1991, Muir et al., 1991, Muir et ...
COPPER Copper production - Repository
About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
High-arsenic copper concentrates - International Mining
“Around 30% of world copper concentrates output contains more than 0.1% or 1,000 ppm As. complex copper concentrates have an As content greater than 0.2% (2,000 ppm) with no upper limit, although China imposes a limit of 0.5% As (5,000 ppm) on imported base metal concentrates.
Copper processing - Roasting, smelting, and converting
Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...
