 · Step 7 Processing on site Once ore is extracted processing it into pure gold must be done Ore is first crushed and then undergoes various processes depending on the nature of associated minerals Processing low grade ore is relatively simple while higher grades require more extensive processing and greater efficiency with gold deposits associated with preg robbing ores The thiosulphate leaching process followed by resin in pulp gold extraction has been developed by SGS to the point where it is a technically and economically viable alternative to cyanidation for some gold bearing ore bodies Whether the leaching is performed in

 · Gold processing 101 Amidst the general fall in metal prices over the last few years the gold price has remained comparatively stable in the US$1 000 1 250/oz range Gold bulls were disappointed that the price did not break through the $2 000/oz ceiling nevertheless the current stable price run has helped to maintain a strong interest in gold Such a procedure will enable the choice of a suitable process for gold extraction The first step should however be mineralogical evaluation of the ore sample Diagnostic leaching is based on the concept that the least stable mineral in the ore matrix will be the first to be solubilized
