The effects of cyanide concentration and protective alkali were investigated, in cyanide process of sulfide gold ore, flotated in Yeung Dong Mine.
The important results of this study are as follows;
(1) Mineral sizes of below 80 mesh were extracted to about the same extent in the recovery of gold by cyanidation.
(2) A gold of above 90% in recovery was obtained when cyanidation was carried out for 24 hours with 0.5% NaCN solution containing 0.05% CaO to which was added 1kg per ton of ore, after pre-aeration for 2 hours.
