epc cyanide gold processing plant

70,000 t/a Environmental Management Project amp; Cyanide

There was a gold mine in T234;wo which had been smallscale mined, and processed by stacking and heap leaching for a long term. Due to the disordered distribution, backward technology and poor management of the plant, a large amount of untreated waste tailings were produced, and a lot of cyanide was left in the waste liquor, which wasted gold resource and pollute the environment.
