Leaching dissolves the gold out of the ore using a chemical solvent. Themon solvent is cyanide, which mustbined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
The leaching process in mining is carried out either as heap leaching or insitu leaching. Precious metals such as gold are extracted from their ores by a cyanide or ozone leaching process. Radioactive metals, such as uranium are extracted by the process of acid leaching.
Heap leaching HL is a flexible and economic mineral processing method, commonly used to extract gold from low grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold containing solution is leached.

12/12/2019· Heap leaching is one of the oldest and the most traditional mining process used to extract valuable metals from specific minerals. This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally, heap leaching was practised 500 years ago.

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
Gold cyanide leaching is a relatively slow process, the leaching time is over 24 hours generally, and the gold leaching rate is improved with the extension of leaching time, but the gold leaching speed is reduced corresponding, and finally, the gold leaching rate tends to a limit value.
