Whats more, the rising of activated carbon adsorption gold technology makes the heap leaching process widely used in the whole world, especially low grade gold deposit and small gold mine. With the rising gold prices in recent years, it further stimulated the rapid development of the gold industry.
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.
Heap leaching has become a popular method of extracting gold, writes mining consultant Nicolaas C. Steenkamp and Leon Louw, writer, editor and specialist in African affairs and mining. Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to
Processing Gold Ores Using Heap Leach Carbon Adsorption Methods By H. J Cecil D. Andrus, Secretary BUREAU OF MINES . This publication has been cataloged as follows Heinen, Harold J Processing gold ores using heap leachsarbon adsorption nidation treatment is the same as that for the agitation cyanidation process. In heap leaching, the
Heap leaching is an industrial mining process of separating precious metals, copper, and other minerals, from ores. It involves a series of chemical processes, through which the mineral ores are piled into the form of a heap, and a leach solution is spread over the ore surface to leach metal from the heap.
Process Introduction 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.
Heap leaching is a process whereby precious metals such as gold and silver are extracted from rock by placing mineralized material on a lined pad (a base) in a heap and irrigating with a leaching solvent, such as cyanide or acid.
Heap leaching is a process that use to treat the gold mine with low grade , cause it`s process simple , easy operation , low energy consumption , investment saving , effective . Scale can be choose , maximum scale can be million tons /day .
At first glance, heap leaching can appear an extremely simple technology; however, without proper characterisation, engineering and design, heap leaching faces significant issues that can affect the overall economic viability of the project.

Heap leaching mining was developed as a mineral processing low grade metal that is more efficient and minimal cost. Compared with conventional cyanidation process of the mineral leaching process with stirred tank Heap leaching has several advantages in the form of designs that use a very simple, operating costs are also minimal, and in requiring less investment, because the heap leaching
Heap leach gold recovery techniques are employed at Ortiz. Caustic cyanide solutions are sprayed onto crushed rock piles, dissolving the metallic gold from within the rocks and carrying it out as a pregnant gold containing solution.
Cyanide heap leaching is a process for recovering gold and silver by trickling cyanide solutions through low grade ore that has been stacked on open air pads (Fig. 1).
He has considerable experience in the permitting and closure of gold heap leach operations in the western U.S. and has lectured in the U.S., Latin America, Europe, Australia and Africa on mine closure planning and design.
Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the available gold.
