Vat Leaching of Finely Crushed Gold Ore

Vat leaching is a simple and efficient mode of effecting adequate contact between the solute and aqueous solvent. It utilizes the countercurrent principle, with the ore to be leached remaining stationary, as differentiated from most counter-current methods, where all materials are moving.

Day 51, Procedures to obtain gold: Vat Leaching Process ...

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.

Cyanide Vat Leaching

in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility. Mine Tailings READ ARTICLE


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 desliming circuit. Traditional vat leaching is a batch process, however,...

Designing a leach circuit should consider both ore-specific factors as well as factors involving the interaction between the ore and process equipment. Achieving the optimum leach performance involves combining operating parameters, such as grind size , residence time , stone conditions (reagent addition levels, temperature, etc.), most of ...

Tank leaching - Wikipedia

Tank leaching is usually differentiated from vat leaching on the following factors: 1. In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Simplicity | INNOVAT Mineral Process Solutions - Vat Leach

INNOVAT’s Continuous Vat Leaching system draws upon existing processes combining standard leaching with fluidized process beds. The result is an exceptionally small process plant with large throughput rates. Significant cost savings are realized thanks to the high process efficiency and recycling of water and lixiviant.

Leaching & Adsorption Resource Book

The goal of leaching is to ‘push the reaction to the right’ ie; consume the reactants to produce the gold complex in solution. Therefore to leach the gold out of the ore and into solution, cyanide, and oxygen must be added to the slurry. Lime is added to the grinding circuit to modify the pH of the slurry to

1.0 INTRODUCTION - Vat Leach

The mining and material handling process has been unmodified for the 10,000t/d Continuous Vat Leach case, and modified only as a result of the reduction in processing rate for the 5,000t/d CVL case. The crushing circuit has been modified as a result of the Continuous Vat Leaching process feed size requirement of -6mm.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of stone reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
