silver leaching process
Dump leaching . Dump leaching is an industrial process to extract precious metals and copper from ores.. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the .

SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SXEW reactor, the first process to take place is solvent extraction, which involves

Keywords: gold, silver, nickel, copper, cyanide leaching, activated carbon adsorption Introduction Gold is recovered from its ores hydrometallurgically by the cyanide leach process. The gold reacts with cyanide according to reaction (Davidson and Sole, 2007): Au0 +2CN– + ½ H 2O + ¼ O2 → Au(CN)2 – + OH– (1) The gold ore after grinding to 80% –5 .
Extraction Of Silver
· The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.
Mines – Asarco
The mine operates four openpits (North Silver Bell, El Tiro, West Oxide and East Oxide). All copper in these pits will be extracted from the ore utilizing dump leaching. The four openpits and other plant facilities are situated on 19,000 acres. Mining affected areas of the facility: 3,900 acres.
Copper extraction
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
