通过对黔西南贞丰某一典型的高粘土质低品位金氧化矿石浸出、粘结剂配比实验和催熟剂 No.1浸金实验研究 ,表明少量复合粘结剂的加入 ,极大改善矿石的性质 ,提高浸取液的溶液渗透性。 4 %复合粘结剂 (内含 15wt%催熟剂 No.1)的掺入量 ,不仅使成球粒在 2 4 h内的抗压强度达到 4 .0 kgf/cm2 ,而且在 2 4 h内氰化反应近乎完全 ,金溶出率高达 96 %。 Through the study of a typical high clay low-grade gold oxide ore in Zhenfeng, southwestern Guizhou, the binder ratio experiment and ripening agent No.1 leaching experiment show that adding a small amount of composite binder greatly improves The nature of the ore increases the solution permeability of the leachate. The incorporation amount of 4% composite binder (containing 15wt% of ripener No. 1) not only made the compressive strength of the pellets reach 4.0 kgf / cm2 in 24 h, but also in 24 h Nearly complete cyanidation reaction, gold dissolution rate as high as 96%.
