| titleOfInvention | METHOD OF PROCESSING COLLECTIVE GOLD-IRON-SULFUR CONTAINING CONCENTRATES |
| abstract | The invention relates to hydrometallurgy of noble metals and can be used in the extraction of gold and silver from refractory sulfide concentrates. The goal is to increase the complexity of processing while maintaining a high degree of extraction of precious metals. Concentrate containing, by weight. %: 29 Fe; 28SiO9.4AlO; 2.6 MgO; 24 s; 4.2 Sb; 2.8 As; as well as 62 g / t Au and 28 g / t Ag, are loaded into the cathode space of a graphite retort, which is an electrolyzer. The process is carried out in a melt medium eutectic mixture of potassium and sodium chlorides with the addition of 6% ferric chloride at 750 ° C for 6 hours. The current is 24 A, the bath voltage is 2.85 ± 0.35. As a result of the process, sublimates of arsenic sulfide, antimony chloride and elemental sulfur are formed, which are collected and treated with water at T: W = 1: 1 to dissolve antimony chloride. Sulfur from the residue is isolated by melting. The solid residue after melting contains noble metals. It is washed of salts, cyanate at pH 11.5 for 12 hours in the presence of resin AM-2B. The cathode deposit is a metallic iron powder. The degree of extraction of products is, wt. %: 90.3 Fe; 84 S; 97 As; 81 Sb; 98.8 Au; 90.6 Ag. Mixtures of potassium – magnesium chloride, sodium – magnesium, lithium – potassium chloride can be used as the chloride melt. |
