Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Nickel smelting Extraction and purification Nickel is recovered through extractive metallurgy it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

The gold is removed from the cathodes by either using a high pressure water spray, sometimes shaking the cathode, and in some cases, the stainless steel cathode is placed into a melting furnace and heated to 2,000 degrees F, to melt the gold from the cathode. The stainless steel cathode, of course, does not melt at this temperature, but such ...
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and in the case of copper/ molybdenum ores separates molybdenite from copper sulphide.
As a critical component in stainless steel and lithium-ion batteries, the waning nickel sulfide resources have many looking at nickeliferous laterite deposits as the future of the industry. Both hydrometallurgical and pyrometallurgical approaches are utilized to process nickel laterite ores, with the best approach depending on the ore composition.
