Valves for gold production with CIL CIP or CIC circuits Neles Valve performance affects the whole leaching process so it is vital to select the right selection ball valves provide a long service life and precise flow control capabilities. Run-of-mine ore is first crushed and ground to a fine particle size.
Cyanide Leaching Mining SGS USA 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
