Gold Extraction and Recovery Processes

All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. Panning is probably the oldest technique used for the recovery of gold. Panning is a type of gravity concentration used by prospectors for the recovery of gold from river beds.

Copper extraction

However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included hand-sorting and gravity concentration. They resulted in high losses of copper.

Copper and compounds

Copper and compounds occur naturally in the environment and is essential to animals and plants. Copper is toxic to many bacteria and viruses. Copper is commonly found as copper (II) in natural waters and the free copper (II) ion is potentially very toxic to aquatic life, both acutely and chronically.
