摘要
研究某褐铁矿型金矿石氰化浸出渣对银和金氰络合物的吸附过程。结果表明,随吸附时间延长,溶液中金络合物浓度降低,而银络合物浓度有所增加。浸出渣对金和银络合物的吸附特点不同,活性炭与浸出渣对金和银络合物的吸附特性也不同。浸出渣对被浸出的铜络合物也有一定的吸附作用,对滤液中的氧化钙有比较大的吸附作用,从而导致矿浆的pH下降。
The adsorption process of silver and gold complexes on cyanidation leaching residue of an oxide ore containing limonite is investigated. The results show that the contents of gold and silver complexes in solution are decreased and increased with the extension of adsorption time, respectively. The characterization of gold and silver complexes absorbed by the ore is different each other. The adsorptive characterization of activated carbon is also different from that of the leaching residue. The leaching residue is able to absorb copper complexe and with more capacity for CaO adsorption resulting in the pulp pH decrease.
