Leaching process.Leaching process-leaching is a mass transfer operation in which we have a solid material which either contains components which are valuable to us or components which are considered an impurity of the solid, no matter what the case, such components are called solute.We take a liquid which is called a solvent and contact it intimately with the solid in order to extract the.
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent.In extractive metallurgy, of gold, it is the process of dissolving a certain mineral or minerals from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes.

Leaching is widely used in the biological and food processing industries, such as the separation of sugar from sugar beets with hot water.The extraction of oils from peanuts, soybeans, sunflower seeds, cotton seeds, and halibut livers.In pharmaceutical industry, many products are obtained by leaching plant roots, leaves, and stems.
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorbs specific minerals and then re-separate them after their division from other earth materials.
Leaching is a chemical process in mining for extracting valuable minerals from the ore.Leaching also takes place in nature where the rocks are dissolved by water.Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained.

Leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation.The materials lost are carried downward eluviated and are generally redeposited illuviated in a lower layer.This transport results in a porous and open top layer and a dense,.
Leaching is a serious problem more so for soluble components e., starches in a diet or fecal material than for fibrous e., cellulose components, and it is recommended that feces be collected as frequently as possible to minimize contact with the water and potential leaching.
Our copper chloride leaching process utilizes our highly effective atmospheric chloride leaching technology, including gold and silver recovery.We have coupled this with world-renowned vsf solvent extraction and electrowinning technology to make a process that is especially effective with low-grade and impure copper feed materials.
