2021-1-4  The most common concentrate extraction techniques are flotation and leaching that have greatly increased the ability to process low grade ore bodies. The waste ground rock and the spent processing water and reagents from the plant are known as tailings. The word tailings is sometimes applied to include coarse mine waste.

SART Process for Gold Recovery and Cyanide

The result is high cyanide consumption, poor gold doré purity and high concentrations of copper-cyanide complexes in tailings that require costly destruction. SART We offer the SART process to remove the metallurgical interference of cyanide-soluble metals and to efficiently recover and recycle cyanide in gold

This process is repeated to concentrate the gold bearing ore and separate it from the waste rock (increasing the grade of the ore). The flotation units catch 70% of the gold collected at Macraes, with the primary roughers collecting the other 30%. The slurry that doesn’t contain any gold is neutralised and sent to the tailings dam.
