Mobile Gold Mill Machinery in South AfricaGrinder Process South Africa is rich of gold resoureces Gold mining industry requires high quality gold milling machinery and beneficiation equipment Gold milling begins when ore material from the mine is reduced in particle size by crushing and grinding

Gold processing preparation of the ore for use in various products For thousands of years the word gold has connoted something of beauty or value These images are derived from two properties of gold its colour and its chemical colour of gold is due to the electronic structure of the gold atom which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

Ore processing consists of the following stages crushing and grinding of the ore addition of process water generally decanted from the tailings pond to form a slurry addition of lime to the ore and cyanide solution to the slurry to leach the gold and silver into solution

The Gold Processing Plant control station includes the water distribution manifold The large barb on the left hand side is the clean water connection Connect this to a pump capable of supplying both the clean process water near 15 LM and the slurry water near 77 Lm to make 30 solids at 2 tph at 15 psi

The carboninpulp process is used to treat low grade gold andor silver ores The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device This is done to produce a feed suitably sized so that subsequent leaching is rapid

Next mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks 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 carboninpulp As the cyanide and oxygen react chemically gold in the pulp dissolves
