硫铁矿在中国硫资源中的地位分析

Analysis on Pyrite's Status in Sulfur Resource of China

硫铁矿是我国的自有硫资源,几十年来我国硫铁矿产业有了很大发展,但随着我国经济对硫资源需求的大幅增加,各种形式的硫产量的迅速提高、进口硫磺及硫酸的冲击等因素,导致了硫铁矿在硫资源中的地位大幅下降。2015年硫铁矿硫仅占国内硫资源的30%,而硫铁矿制酸更是仅占硫酸总产量的22%左右。为了提高硫铁矿在硫资源中的地位,应该提高制酸技术,降低制酸成本,减少尾气排放,加快产业结构调整。

Pyrite is self-owned sulfur resource in China. For decades, pyrite industry has developed greatly, but with a substantial increase on the sulfur resource demand, various forms of sulfur production, imported sulfur and sulfuric started impacting the pyrite＇s status in sulfur resource. In 2015, pyrite accounted for only 30% of the domestic sulfur resource, and pyrite-made acid accounted for only about 22% of the total sulfuric acid production. In order to improve the status of pyrite in sulfur resources, we should improve the technology of acid-making, reduce the cost of acid production, reduce exhaust emissions, speed up the adjuslxnent of industrial structure and increase the degree of intensification of pyrite industry.
