gold ore processing plant carbon regeneration kiln

Activated Carbon Plant--Daiwo Machinery

Activated carbon can be made from different carbon-contained materials, like wood, sawdust, coal, charcoal, peat, lignin, kernel, sugar cane pulp, bone, lignite, oil dreg, etc. Based on different materials, techniques and using areas, different activated carbons can be produced, in which activated carbon made from coconut shell is of best quality and been seen most frequently.

VALVES FOR GOLD LEACHING IN CIL, CIP OR CIC CIRCUITS

from plant to plant, with CIL being the most widely used processing method. In a CIL leaching circuit, a cyanide solution and oxygen are added to the slurry in large steel leach tanks. The gold dissolves from the ore into the solution. The activated carbon is fed into the process from the opposite direction, against the slurry stream.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. 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.
