PDF Dense Medium Separation - An Effective and Robust Pre
To determine if an ore is suitable for pre-concentration using DMS (or other gravity separation techniques), a laboratory scale testing program is generally initiated. Laboratory scale testing usually involves heavy liquid separation (HLS). At SGS, two modes of HLS testing are practiced.

Ten technologies with the power to transform mining
The VK1, operated from an aircraft, incorporates technology to measure subtle changes in the Earth’s gravity field and uses the data to produce a density map which can be used to identify ore bodies, which are otherwise hard to detect. The device has undergone a series of flight tests and improvements since 2010.
PDF Leaching & Adsorption Resource Book
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.

Elution and Carbon Reactivation - Resource book
During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
