进行了硫化锌和含银低品位锰矿联合氧压酸浸的小型试验,以考察影响浸出的各种因素,诸如浸出温度、浸出时间、氧分压和搅拌速度。实验在2L的高压釜内进行。实验结果表明,硫化锌和含银低品位锰矿能相互促进浸出,但这种耦合作用须在一定条件下才会起作用。作者对一些浸出做了探讨。为下一步扩大试验的需要,本文给出了合理的浸出条件:浸出温度,110℃;浸出时间,2h;氧分压,0.6MPa;硫酸用量,1.2倍理论用量。
A small-scale trial of combined oxygen pressure acid leaching of zinc sulphide and silver-containing low grade manganese ore was conducted to investigate various factors that affect leaching, such as leaching temperature, leaching time, partial pressure of oxygen and stirring speed. The experiment was carried out in a 2 L autoclave. The experimental results show that zinc sulfide and silver-containing low-grade manganese ore can promote the leaching of each other, but this coupling must be under certain conditions will play a role. The author explores some leaching. In order to further expand the test needs, this paper gives a reasonable leaching conditions: leaching temperature, 110 ℃; leaching time, 2h; oxygen partial pressure, 0.6MPa; sulfuric acid dosage, 1.2 times the theoretical amount.
