PROCESSING OF GOLD-BEARING CONCENTRATES OF TWO-FOLD HARDNESS |
摘要 |
FIELD: metallurgy.SUBSTANCE: prior to feeding into autoclave the concentrate acid pulp produced by the concentrate pre-treatment with acid is mixed with addition of mercury salts. Autoclave leaching is conducted at 225-235°C and terminated upon reaching the pulp redox potential in the range of +700÷730 mV relative to standard hydrogen electrode. As addition mercuric sulphate (II) or mercuric nitrate (I) is used in amount of 5-50 g as recalculated to mercury per 1 t of concentrate. Acid concentrate pulp with mercury salt addition is mixed at room temperature for 0.5-1 h.EFFECT: higher gold yield.4 cl, 2 tbl, 1 ex |
