硫化锌精矿加压氧浸回收有价金属的工艺

Valuable Metals Recovery Process from Pressure Leaching of Sulfuric Zinc Concentrate

介绍了硫化锌精矿加压氧浸的原理和设施,同时处理以锌为主的原料和富含铅银及有价金属的原料,在不改变技术参数及配套设施条件下,分三个步骤来分别富集回收主金属锌、重金属铅银及稀散金属,可获得高锌回收率及高有价金属综合回收率,为一种环保节能的清洁生产工艺。

This paper introduces the principle and facilities of sulfur zinc concentrate pressure leaching, as treating the material mainly zinc contained and with lead-silver, other valuable metals, under the same technology parameter and facilities, high zinc recovery rate and high comprehensive recovery rate of valuable metals could be achieved, which was a kind process of energy saving and environment protection.
