【摘要】 以广西某新开采的独立银矿的矿石所制得精矿粉为原料,加入适量软锰矿粉(MnO2)和硫酸,在95℃下预处理2 h后,采用矿浆电解法,在自行研制的电解槽中进行单因素提取银的实验研究。在温度50℃,电流密度0.035 A/cm2,液固比7∶1,电解时间10h的电解条件下,银的浸出率可达95.9%。更多还原

【Abstract】 The concentrate powders from an independent silver mine in Guangxi province were used as raw materials.After pretreatment at 95℃ for 2h with addition of proper amount of MnO2 and H2SO4,silver in the concentrate powders was extracted by the slurry electrolysis method in a self-made electrolysis bath.Under the conditions of temperature 50℃,current density 0.035 A/cm2,liquid/solid ratio 7∶1,electrolysis time 10 h,the leaching rate of silver is 95.9%.更多还原
