The process of gold leaching demands the use of cyanide because it escalates the separation process of extracting the gold from the ore. One of the main reasons cyanide leaching is performed as an alternative method to separating gold from an ore is because it is much safer than using liquid mercury for the extraction.This process is repeated to concentrate the gold bearing ore and separate it from the waste rock (increasing the grade of the ore). The flotation units catch 70 of the gold collected at Macraes, with the primary roughers collecting the other 30 . The slurry that doesn’t contain any gold is neutralised and sent to the tailings dam.
Jul 04, 2019 Wolframite mineral processing method mainly in gravity separation, and includes four parts pre-selection, gravity separation, concentration and recovery. By pre-selection and discarding the waste rock which accounts for 50 of the raw ore, the WO3 grade of the ore is enriched from 0.25 ~ 0.3 to 0.45 ~ 0.8 , and the recovery is 96 ~ 98 .Processing of different refractory gold ores by wet chlorination, followed by chloroauric complex (HAuCl4) separation by adsorbtion ,on macroporous.
