Different ore has different gold leaching process, different ore with different properties must adopt the proper gold leaching methods.Here is a brief introduction of the common gold leaching methods for gold mining plant. Extraction of gold from ore should be at least two steps, first of all, the prepared work, also called pre-talking work, which can be formed by crushing and separating After 24 hours, direct cyanide leaching of the initial ore resulted in only 54.8% gold recovery. However, cyanidation after dissolving the ore sample in hydrochloric acid (HCl), sulfuric acid (H 2 SO 4), ferric chloride (FeCl 3) and nitric acid (HNO 3), re-spectively, increased the gold recovery to 98.1%. This shows that the ore is a sulfide

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.
effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical
Vat leaching has been widely used by the copper industry on higher grade copper ores but has been used in only a few small operations on that size gold or silver ores. however, such a plant should be considered for a modest tonnage of a few million tons, 3 to 7 g per mt (0.10 to 0.20 oz per st), of carlin-type leachable ores crushed to 9 mm
Heap leaching is an effective gold ore processing technology for low grade gold ores.Heap leaching is also one of the cyanide leaching methods.This method is mainly used to deal with oxidized ore, by-product ore or off-balance ore produced in the process of shaft opening up, which all contain low-grade gold, and also used to deal with gold-bearing tailings and gold-bearing cinders from non

Bacterial leaching was combined with thiourea method for the gold leaching from ores. For gold bearing pyrites, biological pre-oxidation has been generally perfomed. In the present study, we carried out the biological treatment to the high silicate bearing ores by using the iron
Gold can be leached from stone through alkaline or acidic-based products, including halogens, such as chlorine, iodine and bromine. Halogens are reactive, non-metal elements with seven electrons in their outer shell which allow them to easily combine with other elements. The

Metallurgy - Metallurgy - Leaching: Oxides are leached with a sulfuric acid or sodium carbonate solvent, while sulfates can be leached with water or sulfuric acid. Ammonium hydroxide is used for native ores, carbonates, and sulfides, and sodium hydroxide is used for oxides. Cyanide solutions are a solvent for the precious metals, while a sodium chloride solution dissolves some chlorides.
During gold heap leaching an alkaline ph 9 to 11 is main tained but afterwards the piles are usually rinsed with fresh water and the ph approaches a more neutral range thus much of the free cyanide can be volatilized leach residue near the surface of the,Heap leaching in gold ore good quality.
