下流式吸附槽、又充气吸附槽以及高速搅拌吸附槽在煤金团聚（ＣｏａｌＧｏｌｄＡｇｇｌｏｍｅｒａｔｉｏｎ简称ＣＧＡ）工艺从堆浸尾渣中提金的试验结果比较表明：相同试验条件下，下流式吸附槽达到相同的金回收率，搅拌速度较高速搅拌吸附槽及自充气吸附槽明显降低，设备效率明显提高，且放大性能良好。下流式吸附槽连续性试验证明两级串联就能达到ＣＧＡ工艺要求指标，级数和搅拌速度均较文献报道有显著降低，说明下流式吸附槽具有工业应用潜力。 The results of the comparison of the experimental results of gold extraction from the heap leach residue in the downflow adsorption tank, the aeration adsorption tank and the high speed agitation adsorption tank show that under the same test conditions, the downflow adsorption tank achieves the same Gold recovery rate, mixing speed higher speed stirring adsorption tank and self-inflating adsorption tank was significantly reduced, equipment efficiency was significantly improved, and the amplification performance is good. Downstream adsorption tank continuity test proved that the two-stage series CGA process can meet the technical requirements, series and stirring speed were significantly lower than reported in the literature, indicating the downstream adsorption tank with industrial potential.
