摘　　要：本文从化学热力学角度讨论了黄铁矿在低温低压条件下通过化学作用氧化的历程，指出了决定黄铁矿氧化速率的步骤是黄铁矿的溶解作用。This paper discusses the course of pyrite chemical oxidation under low temperature and low pressure in chemical thermodynamics, pointing out that control step of rate of pyrite oxidation is pyrite dissolution. The chemical equilibrum analysis of a water sample is presented in the paper as well.

关 键 词：黄铁矿 化学热力学 化学氧化 速率决定步骤
