摘　　要：锌精矿不经焙烧而采用三价铁溶液或二价铁溶液为溶剂直接浸出,考察了锌精矿和中浸渣在一定的硫酸浓度和浸出时间、粒度、氧分压对浸出过程的影响,在适宜的工艺条件下锌的浸出率可达到96%以上。Zinc concentrate is directly leached with Fe^3＋ or Fe^2＋ solution without roasting. It studies concentration of sulfate acid, contact time, particle size and oxygen pressure to detemine their influence on the leaching of zinc concentrate and the residues from the neutral leaching process. Under the proper conditions, the leaching efficiency of zinc could reach above 96%.
