快速浮选提高锌渣中银回收率的试验研究
Increasing silver recovery from zinc leach residue by fast flotation
摘要
Abstract
To handle the refractory zinc leach residue out of the high-temperature and high-acid leaching zinc process, the effects of material composition, silver occurrence, the combination collectors and modifiers on the flotation indexes of silver are studied in this paper. The results showe that under the optimal pharmacy system of ammonium dibutyl dithiophosphate and B sulfur nitrogen(2:1) as assemble collector 800 g/t,(NaO3P)6 600 g/t, Na2S 800g/t ,the silver concentrate can be get after open process optimized whose grade is 2 301 g/t with the recovery rate of 57.29 %. The recovery increases by 17.24 % compared to the unoptimized open circuit test (40.05 %). Silver concentrate whose silver grade is 3 087 g/t, recovery rate 5.67 % , and the other silver concentrate whose silver grade is 2 186 g/t, recovery rate 61.23%are achieved by the closed circuit process.关键词
