文章叙述了研究低温对铜置换指标及置换渣沉淀影响的必要性。文章分析了科温拉德斯克矿山表外矿石堆浸溶液在不同温度制度和不同液相酸度下进行铜置换沉淀的研究结果。研究发现,在低气温季节进行铜置换沉淀应使用酸度较高的原始溶液。指出,在溶液 The article describes the necessity of investigating the effect of low temperature on copper substitution index and displacement residue deposition. In this paper, the results of the research on the copper displacement precipitation of the ore heap leaching solution at different temperature regimes and different liquid acidities in the Coviradsk mine are analyzed. The study found that in the low temperature season copper displacement sedimentation should use the original solution of higher acidity. Pointed out that in solution
