Gold vat leaching process is currently widely used in small-scale gold mines, because of a series of advantages including high recovery rate, strong adaptability to ore, low cost and simple process. The basic principle is first to leach the gold from the ore with cyanide solution containing oxygen, and then to extract the gold from the leaching solution with zinc powder or zinc wire.

Introduction of Vat-LeachingVat leaching has been around since Roman times, but had become viable in 1896, when cyanide leaching began in earnest with the Merrill-Crowe Process.In an article in the Engineering and Mining Journal in December 1999, Lou Cope described the first vat leaching at Homes take in 1901, which later improved the process in 1906 by adding a des circuit.

Precious Metal Heap Leach Design and Practice Daniel W. Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods.

Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settling-out of solids

One example of a leaching process that uses vat leaching is gold cyanidation, the process of extracting gold from low-grade ores. In this process, a dilute solution of sodium cyanide (NaCN) is used to leach the Au into solution. The concentration is usually 0.01-0.05 % cyanide, or 100-500ppm.

Gold ore Prominer maintains a team of senior gold processing engineers with expertise and global experience These gold professionals are specifically in gold processing through various beneficiation technologies for gold ore of different characteristics such as flotation cyanide leaching gravity separation etc to achieve the processing plant of optimal and cost-efficient process designs

Pump leaching is a process that grind gold mine with low grade to a certain particles , heap up on the leakage-proof bottom mat that concreted by pitch , concrete or plastic cloth , spray the low concentration cyanide solution , alkaline solution ， nontoxic solvent ， dilute sulphuric acid on the stock heap , make the gold dissolve ， the solution with gold heap up , then use active carbon

1. Introduction. The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006).After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching.

Jul 21, · Traditionally used for oxide gold and copper ores and sometimes nickel laterite ores, vat leaching of PSP ore produced encouraging results towards a proof of concept and delivering a smaller

After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

The Vat Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. Treatment of ore is site-specific as determined by metallurgical tests. Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottle-roll tests of finely ground material are run
