Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates.
2018 8 24ensp;0183;ensp;An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The

700t/d gold ore mineral processing plant in Zimbabwe was contracted by Xinhai. The plant adopted the CIL technological process.
The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach (oxidative)
The AMIRA Gold Processing Technology project is a collaborative industry funded project which has operated since 1984. Over the last 33 years the project has covered a wide range of topics within the general areas of gold ore processing and environmental management of tailings.

2018 8 24ensp;0183;ensp;Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold
2013 1 3ensp;0183;ensp;Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
