The first step is comminution (grinding) to increase surface area and expose the gold to the extracting solution. The extraction is conducted by dump leaching or heap leaching processes. Sodium cyanide is produced on a billionton/year scale mainly for this purpose.

3. Magnetic separation: After washing, the 02mm material flows into the drum magnetic separator to remove the magnetic ore, and then is stored in the slurry pool. 4. Gravity Separation: The 210mm material will flow to the gold sluice box, so the 210mm gold particles can be captured. And the +10mm material will be sent to the waste pile.
The concept of conflict diamonds or "blood diamonds" emerged in the late 1990s when it became evident that several violent civil wars in Africa were connected to mining and trading of rough diamonds. In 2006, the Geological Survey was asked by the Department of State to help address illegal diamond mining in Africa.
This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of preconcentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners ...
