The iron in the zinc sulphide concentrates mainly comprises marmatite and pyrite.

本文研究出一种可靠的、确定精矿矿物组成的化学分析方法，着重于测定铁在精矿各矿物中的分布，及铁闪锌矿铁含量的变化规律。

The experimental results proved the intermediate product of H2S in the leaching of marmatite. The results also showed that oxygen, element sulfur disperser as well as chloride ions could accelerate the electrochemical oxidation of marmatite in sulfuric acid. The electrochemical oxidation of sphalerite was retarded but that of marmatite was promoted with the increase of acidity.
