5) cyanidation leaching
氰化浸出
1.
The investigation of preoxidation leaching mechanism shows that the detrimental ions which are liberated during the grinding process are oxidized into ions unharmful to cyanidation leaching in the preoxidation process.
加强充气搅拌预氧化可将含金硫化矿在磨矿过程中产生的、对氰化浸出有害的难免离子氧化成对氰化浸出无害的离子,同时在磁黄铁矿和白铁矿颗粒表面生成Fe(OH)3薄膜,阻止了它们的进一步溶解,从而大大提高了金银的氰化浸出率。
2.

氰化物浸出
cyanide leaching
q 1 nghuawul一nehu氛化物浸出(eyanide leaehing)以碱金属氰化物(KCN、NaCN)水溶液作为浸出剂的浸出方法。氰化物的浸出作用在于氰酸根(CN一)能够与金属离子形成稳定的配位离子,从而增大金属离子在水溶液中的溶解度;而更重要的是降低了金属与金属离子之间的氧化一还原电极电位,使被浸出的金属易被氧化溶解。在提取冶金中,氰化物浸出目前只应用于金银的提取(见氛化法提金)。 (曹彦)
