Vat leaching

Other articles where Vat leaching is discussed: gold processing: Cyanidation: ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced. The huge heaps described above are sprayed with a dilute solution of sodium cyanide

Heap Leaching, Heap Leaching Consulting, Heap

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.

Definition of carbon

Definition of carbon-in-leach process A process step wherein granular activated carbon particles much larger than the ground ore particles are introduced into the ore pulp. Cyanide leaching and precious metals adsorption onto the activated carbon occur simultaneously.

EFFECT OF SILVER, NICKEL AND COPPER CYANIDES ON GOLD

Keywords: gold, silver, nickel, copper, cyanide leaching, activated carbon adsorption Introduction Gold is recovered from its ores hydrometallurgically by the cyanide leach process. The gold reacts with cyanide according to reaction (Davidson and Sole, 2007): Au0 +2CN– +

The recovery of gold from refractory ores by the use of

Recently, the U.S. Bureau of Mines examined the recovery of gold by chlorination of refractory carbonaceous and sulfidic ores, comparing various treatment methods in which a ground ore pulp is contacted with chlorine gas and activated carbon is added to the pulp for a carbon-in-chlorine leach (CICL). The objective of this research was to demonstrate the basic feasibility of CICL technology.

These reduce the gold yield by attracting gold meant for the activated carbon. Simultaneous leaching and absorption help minimize the problem. CIP-CIL versus Agitated Tank Leaching. Process Description. The first industrial CIP plant was installed in South Dakota. A CIP circuit utilizes the same flowsheet as an agitated leach circuit up to the

pH/ORP measurement Cyanide leaching process

The carbon captures the dissolved precious metal in solution through a mass transfer process known as adsorption. The carbon moves counter-current to the pulp flow so that the new carbon contacts with the lowest concentration of gold-bearing solution in the final CIP tank. The plant removes the loaded carbon at the first CIP tank

Improving the recovery of gold and copper in a CIP

Rinsing carbon in a cold caustic cyanide solution resulted in good elution of copper prior to the gold elution stage. The copper-free loaded carbon was easily treated for gold with very high elution and electrowinning efficiencies of 96 and 98% respectively.

Vat leaching can be considered when an ore body does not have the grade or quantity to be a candidate for normal agitation leaching, and as an alternative to heap leaching. At a location where there is excessive rainfall, such as more than 120 in./yr, or even a short and intense rainy season on the order of 50 in., the solution in heap leaching can become seriously diluted.

Carbon in pulp

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Elution and Carbon Reactivation

the gold loading capacity of carbon is reduced with increasing temperature. Low ionic strength water (no dissolved salts) is used to enable the gold to be stripped from the carbon. The loading capacity of activated carbon for gold increases in the presence of ions such as Ca2+ (calcium) and Mg2+ (magnesium). Hence, desorption of gold from carbon

Science Break: Metal Leaching

The term metal (or metallurgical) leaching refers to the processes involved in separating useful metals from non-valuable ore constituents. The science behind these processes, while not a very glamourous topic, is important: beyond the obvious practical necessity of extracting the metals, leaching methods historically have left behind toxic waste products, so modern improvements represent
