The manual is all about VAT Leaching Technology which is a low cost technology for recovery ofgoldfrom fresh ore or from tails left from previousCIL processand from Small Scale Miners.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
GOLD ELUTION AND ELECTROWINNING At Nesch Mintech we have ten (10) gold elution machines. Three of them are high pressure machines and the rest are low pressure machines. High pressure machines operate for 24 hours while the low pressure machines operate for 48 hours.
Electrowinning is most often used to recovergoldand silver fromeluates producedby theelutionof activated carbon.
CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from anothergoldextraction process called CIP or carbon-in-pulp process.
Goldfrom the pregnant thiourea solution is recovered by transferring the solution from theelutionsection to holding tanks for an electrowinning section. Duringelectrowinning, the solution is circulated between the holding tanks and electrowinning cells.

Agoldbar is stamped with a serial number at a U.S. refinery in 2001. The bar, which weighed about 40 pounds (18 kilograms), was one of ninegoldbars poured that day. Removing thegold-bearing rock from the ground is just the first step. To isolate puregold, mining companies use a complex extractionprocess.
The ZADRA system is anotherelution processwheregoldthat is adsorbed on to activated carbon is desorbed from the carbon by a reversal of the adsorption kinetics.
More than 30 kinds of solutions can be chosen for the metal, non-metal and tailings, our experts working in the laboratory to research the best solution for mine samples each day. Best solution + best design + best research, that could create a best mining

Ore processingis a 24 hour operation. Ore is stockpiled (1) at theprocessingplant, and theprocessbegins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. ... This ‘loaded’ carbon is then pumped to theelutioncircuit (6) where thegoldand silver is washed off with ...
