摘要:

为了解决青海某金矿选矿厂选矿系统中存在的药剂用量大、作业时间不合理及浮选指标低等问题,在原浮选工艺的基础上,开展浮选药剂加药点及用量优化试验研究。结果表明:通过对Na2CO3、CuSO4调整剂和丁铵黑药捕收剂加药点进行优化,将Na2CO3加药点由分级泵池移至调浆槽,CuSO4及丁铵黑药加药点由调浆槽移至分级泵池,矿浆的矿化程度逐渐转好,泡沫结实且泡沫层稳定;通过对浮选药剂用量进行优化,Na2CO3、CuSO4及丁铵黑药用量分别减少了1.0,0.05,0.035 kg/t;经优化后,浮选指标有所改善,精矿产率和回收率分别提高了0.31%和3.53%。与原浮选药剂加药点及用量相比,浮选药剂加药点及用量优化后的浮选指标得到较大提升,药剂消耗量显著降低。

Abstract:

 In order to solve the problem of high dosage,unreasonable action time and low flotation recovery rate of a gold mine dressing plant in Qinghai Province,on the basis of the original flotation process,the experiment was carried out on the optimization of the flotation reagent dosing point and dosage.The results showed that by means of the optimization test of the sodium carbonate,copper sulfate regulator and ammonium dibutyl dithiophosphate collector dosing point,the sodium carbonate dosing point was removed from grading pump pool to agitation tank,copper sulphate and ammonium dibutyl dithiophosphate was removed from agitation tank to grading pump pool,the degree of mineralization was good,foam was seed,foam layer became stability.By means of the optimization of flotation reagent dosage test,the sodium carbonate,copper sulphate and ammonium dibutyl dithiophosphate consumption reduced 1.0,0.05 and 0.035 kg/t respectively.Process parameters were improved,the concentrate yield and recovery rate increased by 0.31% and 3.53% respectively.Compared with the original flotation reagent dosing points and dosages,the floating indexs were improved greatly and the flotation regent consumptions are significantly reduced.  

Key words: gold ore, flotation, dosing point, reagent dosage, process optimization, consumption reduction, effi-ciency increasing
