Addition Of Sodium Cyanide In The Ball Mill

Dissolve Gold and Silver with Cyanide

In our particular EXAMPLE process the leaching actually begins in the ball mill, where sodium cyanide, in the form of barren solution, in addition to a 20% sodium cyanide solution, is added to the ball mill feed. Oxygen must also be dissolved into solution and violent agitation is

How to Precipitate Mercury from Gold Silver Cyanide Leach

Mercury Extraction in a Laboratory Ball Mill. Tests were conducted with all four ores to determine the effect of CaS addition on mercury, silver, and gold during grinding. A 50-pct-solids slurry containing 1 lb/st NaCN, enough lime to give a pH of 11, and 0.1 lb/st CaS was added to a laboratory ball mill and ground for 45 min.

Sodium cyanide Wikipedia

Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:
