2020-6-5The traditional reason that intensive cyanide leaching on gravity gold concentrates is conducted is about managing security i.e. theft. While intensive leaching has its advantages for example the gold enters the same soluble gold recovery stream as the CILCIP gold and more consistent quality Dore is produced smelting is a reasonable route
Thus in gold-ore treatment leaching with cyanide solution follows and in some cases takes place during the grinding process. Leaching is much more efficient on particles which have large surface areas in relation to their mass and in such cases overgrinding may not be a disadvantage as the increase in power consumption may be offset by the increased gold recovery

If suitable leaching techniques are identified then coal fly ash could serve as a useful source of valuable minerals including rare earth elements REEs. In this study three microbial strains Candida bombicola Phanerochaete chrysosporium and Cryptococcus curvatus were tested on their performance of leaching
