  • Common Basic Formulas for Mineral Processing Calculations

     · Concentration and Recovery Formulas. These are used to compute the production of concentrate in a mill or in a particular circuit. The formulas are based on assays of samples and the results of the calculations are generally accurate— as accurate as the sampling assaying and crude ore (or other) tonnage on which they depend.

     · Marmato Colombia has been an important centre of gold mining since before the first Spanish colonizers arrived in 1536. The Marmato deposit is hosted in a dacite and andesite porphyry stock as sheeted sulphide-rich veinlet systems. The district is currently experiencing a surge in both major mining projects and artisanal mining driven by sustained high gold prices.
