Project Description


Achieve optimal gold recovery with minimal impact on the environment. The Pineer gold cyanide leaching process enables sustainable and cost-effective gold recovery >90%.

  • Comes from one supplier, responsible for the whole package.

  • Provides mechanical and performance guarantees for the entire plant unit, with clear battery limits for engineering and implementation.

  • Provides optimal process performance with safe operation and maintenance.

  • Offers savings in design and manufacturing.

  • Delivering processing facilities to global environmental standards with localized vision.

CIL plant mainly applies for the process of above 1.0g/t grade gold ore, and gold ore with large bearing ore volume: silver, platinum, copper, etc. As CIL method sees a better performance in extracting these minerals at the same time.


Gold leaching process (CIL) is an efficient design of extracting and recovering gold from its ore. By chemical cyanide and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of >95%. It has become the first choice of modern gold mining and benefication plant design.

The gold leaching plant (CIL) includes feeding,crushing, sieving, milling&classifying, thickening, cyanide leaching, carbon adsorption, desorption & electrowinning, and final smelting,etc.

Gold ore been crushed & milled into slurry form, is pumped directly into thickener to adjust the slurry density; then it is pumped into leaching tanks and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon; this process is called Carbon-In-Leaching Process (CIL).
