Cyanide Leaching Mining SGS

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

Gold is also found in ocean water. However, the process for retrieving gold from ocean water costs more than the gold itself. How is gold used today? Gold has been used for thousands of years to make jewelry and coins. Today it is still used for jewelry and for some collector's edition coins. Gold is also considered an important and reliable investment.

With the cost of gold now at about $350 per troy ounce, it is well worth modifying the process to effect such savings (Fig. 1). Just as savings can be realized by decreasing variance from finger to finger, the chemical makeup of the bath and the operating conditions used can significantly decrease the variance of gold from point to point on each finger or part.

Energy efficiency of photosynthesis   Britannica

Energy efficiency of photosynthesis Britannica

Energy efficiency of photosynthesis. The energy efficiency of photosynthesis is the ratio of the energy stored to the energy of light absorbed. The chemical energy stored is the difference between that contained in gaseous oxygen and organic compound products and the energy of water, carbon dioxide, and other reactants.

Extracting Gold  HowStuffWorks

Extracting Gold HowStuffWorks

How Gold Works. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold bearing carbon.

Separating the gold from the ore. Smelting involves heating the gold with a chemical substance called flux. The flux bonds with the contaminants and floats on top of the melted gold. The gold is then cooled and allowed to harden in molds, and the flux contaminant mixture (slag) is hauled away as a solid waste.
