Gold mining, crushing, Zimbabwe, jaw crusher, cone crusher . 1.0 Introduction . Gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted (Richiewiki, 2010). The gold ores are usually big and. have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted

CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are:

Free-Milling Gold Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 m. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold

shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2-5” to 160 microns. The mined ore is fed using a Grizzly Feeder, F-101, into a Jaw Crusher, J-101, where 80% of the ore is crushed to 1.75” or smaller. The remaining 20% are recycled back into F-101 (not shown on PFD)

low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad. A sprinkler system provides a continuous spray of alkaline cyanide solution that percolates through the ore dissolving the gold. The gold bearing or pregnant solution is collected and pumped to a gold recovery plant
