Leaching (metallurgy)
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts. These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially much less harmful

Managing Soil Salinity publications.tamu.edu
Leaching is the process of adding sufficient water to the soil to dissolve salts and carry them out of the root zone. a. When the salt concentration in the soil is less than that in the plant, water moves from the soil into the plant. b. When the salt concentration in the soil is equal to that of the plant, there is no net movement of water. c.

TWO STAGE LEACHING PROCESS FOR Cu AND Zn
The Two Stage Leaching Process described in this paper consists of classic acid leaching followed by a bioleaching step. Acid leaching serves to leach the oxide minerals, but when O 2 is introduced as an oxidant partial oxidation of sulphide minerals is expected. Bioleaching serves to leach the sulphide so that at the end of the acid

Copper Leaching Method Metallurgist amp; Mineral Processing
It is seldom found necessary to heat the liquors in leaching proper, the strength of acid lixiviant used being sufficient to effect solution of the copper at ordinary temperatures. Most ores amenable to the leaching process carry such small quantities of the precious metals that they can be neglected.

Countercurrent Tower Process Gold Leaching
The Kamyr countercurrent tower leach process consists of a true countercurrent leach with a flocculated ore and fibre mixture entering the top of the tower and a cyanide solution or alternative lixiviant as well as a barren wash solution entering the bottom of the tower. The Kamyr countercurrent tower leaching system has been developed for processing gold, silver and other leachable ores.

Gold and Silver Leaching by Cyanidation
Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
