zinc sulphide

A method is proposed to determine free native silver and free silver sulphide in lead-zinc concentrate.

拟定了分离测定铅锌精矿中游离硫化银和游离自然银的方法.

The authors set forth the method which adopted dry filtering method to measure the zinc content in zinc sulphide concentrate and by comparison, it is considered that this method for measuring zinc content in zinc concentrate is faster and preciser than twice settling separation method.

作者阐述了用干过滤法测定硫化锌精矿中锌的含量的方法与步骤，通过对比，认为采用该法测定锌精矿中锌的含量较两次沉淀分离法要快捷、准确。

In this paper the heat balance of pressure leaching for zinc sulphide concentrate is calculated.

笔者对硫化锌精矿加压浸出过程的热平衡进行了计算.

Below the main ore layers of the South China type massive sulphide deposits there frequently occur discordant ore bodies formed by fissure filling, hydrothermal metasomatism and brecciation. The ores fall into the copper-sulphur type and lead-zinc type.

华南型块状硫化物矿床层状矿体下盘往往存在着裂隙充填、热液交代和角砾岩矿化形成的不整合矿体，其矿石成分主要有铜-硫和铅-锌两种类型。
