Mineral Reserves are estimated based on the following assumptions: metal prices of 1,300/oz Au; cutoff of g/t recoverable Au (equivalent to a NSR cutoff of /t); recovery is variable throughout the block model with average life of mine metallurgical recovery being 56% for all ore; and no dilution and mining recovery of (both already accounted for in the resource .

Gold recovery using the heapleach method is based on the process of applying a leachate that usually contains about 100 to 600 parts per million (ppm) ( to percent) NaCN in a waterbased solution to a large pile of crushed or runofmine rock and, occasionally, mill tailings (Hoye, 1987; van

 · Abstract. Bioleaching is a simple and effective technology for metal extraction from lowgrade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal ores and minerals can be treated by ...

 · Oxidised material can be directly leached to extract the contained gold without expensive pretreatment. Hence the natural oxidation of pyrite in refractory goldbearing stockpiles may increase the profitability of stockpile reclamation by enabling gold recovery using direct cyanide leaching.

leaching, which is preferred over heap leaching due to the low recovery associated with the heap leaching technology. The problem is to find the breakeven price of gold for this mining operation. The process is currently unprofitable with a gold price around 300 per ounce. Process Description Unit 100 – Size Reduction of Ore
