the mining process. the mining process. 1. mining open pit and underground. approximately two kilometres, via a tunnel through union hill, to the mill and waste rock embankments. large electromagnets remove any steel debris excavated from the old martha mine workings. this process removes 93% of the gold and 70% of the silver.
the gold milling process may be broken down into three basic procedures: 1 sorting the ore by size 2 crushing the rock 3 extracting the gold . first, miners raise the ore out of the mine in wheeled carts pushed on rails and take it down to the mill.
gold belle mine and milling co. the gold belle mining and milling company was formed around 1900 by wildmand and williams near the rough mining town of wildman. the gold belle co. erected a 50 tone cyanide mill to process the gold ore. today on the cooling tower and concrete foundation remain as evidence of the short-lived gold rush.
a stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. it uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining.
mining and milling. mining. the mill was originally designed with a capacity to process 4.8 million tonnes of ore per year, but the actual mill throughput in 2011 was approximately 5.7 million tonnes per year. gold recovery in the cil circuits is generally 90% for the sulphide concentrate and 25-30% for the flotation tailings.
we no longer use chemicals at our mine to process the ore. due to the fact that oil makes gold float, we can not use oil on the stamp mill so we substitute oil with sorghum syrup we have to apply the sorghum syrup daily to the camshaft. the price memorial building at the north georgia college has 16 ounces of gold on the dome.
in all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill. at the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the ore.

Environmental Protection and Health One
LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
To Improve the Purity Two
Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.
High Efficiency Three
LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
Low Cost Four
Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
