Pyrite powder is the main raw material of sulfur, and its resource distribution status is as follows:

1. China's sulfur resources have few rich ores and many lean ores. The first grade products with a sulfur grade of more than 35% account for only 3% of the pyrite reserves. Ninety-seven percent of the pyrite ore is a low-to-medium grade ore with a sulfur content of 12% to 35%. The proportion of lean mines ranging from 12% to 20% is relatively large. The grade of associated pyrite in China is quite different. The minimum sulfur content is 1.5%~3.0%, the maximum sulfur content is 42%, and the average grade is 10% to 30%. Four. The sulfur content of natural sulfur deposits in China is mostly low. Currently, only small-scale mining is conducted in Qinghai, and the rest has not been used.

2. Pyrite powder is symbiotic with many beneficial ingredients. Many pyrite deposits in China have associated and symbiotic beneficial components. For example, skarn, hydrothermal, and volcanic deposits are composed of copper, lead, zinc, molybdenum, gold, silver, cobalt, gallium, selenium, and tellurium. , Cadmium, germanium, thallium and other colored. There are minerals such as iron, manganese, coal, bauxite, and clay minerals in the sedimentary deposits, which are conducive to comprehensive development and recycling. Some ores contain high levels of impurities such as arsenic and mercury, which are harmful to sulfuric acid production.

3. The mining conditions are poor. Most pyrite deposits need to be mined underground, and the ore reserves suitable for underground mining account for about 65% of the total pyrite reserves. The mining conditions are good, and the ore reserves suitable for open fields only account for about 15% of the total pyrite reserves. At present, only the shallow resources in a few mining areas such as Dajiangping in Guangdong Yunfu and Anhui can be exploited. Associated pyrite resources are suitable for open mining and underground mining each account for about half.
