Pyrite mine is a kind of natural mineral from mining, it is a kind of basic chemical raw materials, It can be applied directly to produce sulfuric acid, most of which are used to produce the chemical fertilizers.
In theory, the sulfur content of pyrite can reach 53.45%, and iron content can reach 46.55%, whereas, in practice, the sulfur content can normally reach 35%. The original pyrite from mining often contains silicon, lead, zinc, copper, arsenic, carbon and so on, its color may be light aurichalceus or dark gray, the surface has metallic luster, and the powder is usually dark gray.
The sulfur content of pyrite can be promoted to be about 48%, after going through the procedures of processing, sorting out miscellaneous stones, drying, crushing, and sorting out etc. Then, they can be used as increase sulfur agent in melting and casting, and other industries like grinding/ abrasive tools, lithium batteries, environmental protection and counter weight.
