11 PHASES OF A MINING PROJECT The gold content of a good grade gold ore may be only a few onehundredths of a percent Therefore the next step in mining is Beneficiation includes physical andor chemical separation techniques such as gravity concentration magnetic separation electrostatic

Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore

Iron Ore Mineralogy Processing and Environmental Issues summarizes recent key research on the characterization of iron ores including important topics such as beneficiation separation and refining agglomeration eg production of pellets or powders blast furnace technology for smelting and environmental issues relating to its production

extract gold releasing large amounts of the toxic element into the environment Alternatives to mercury have been suggested over the years to little avail A group of miners in the Philippines has demonstrated that borax when used as a flux for smelting gold out of heavy mineral concentrates is an effective and safer substitute for mercury

First the gold ore is crunched up into little pieces then a cyanide solution is used to dissolve the particles of gold The remaining solid rock and other minerals are filtered out and the gold is precipitated out of the cyanide solution this raw gold may also contain silver and copper

Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground necessitating the removal of layer upon layer of overburden and ore In many cases logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden
