Cyclic degradation of thiocyanate in cyanide barren ...

2022-1-1  The results of cyclic treatment of cyanide barren solution showed good regenerability of MnO x /Ca and gradual reduction of undesired secondary salts (especially SO 4 2− ions) in the degraded liquid, which made it a potentially reliable technique to regulate the thiocyanate concentration during the cyanidation process of gold ores economically.

Effect of Impurities on Cyanide Leach Solution

2016-7-27  Sodium cyanide is regenerated in the same reaction, the cyanide loss, therefore, being much less than at first would be expected. Calcium is introduced in the form of lime (CaO) for the purpose of providing a neutralizing agent. Its use results in the formation of calcium carbonate (CaCO3) and of calcium sulphate (CaSO4).

4. CHEMICAL AND PHYSICAL INFORMATION

2012-2-6  It may exist in polymeric forms. The cyanide compounds in which cyanide can be obtained as CN– are classified as simple and complex cyanides. Some simple cyanides are soluble in water (sodium cyanide, NaCN; potassium cyanide, KCN; and calcium cyanide, Ca(CN)2), while others are sparingly soluble or almost insoluble (copper (I) cyanide, CuCN).
