The upstream of gypsum industry chain mainly includes raw materials and fuel power required in production and processing, including natural gypsum and industrial by-product gypsum (phosphogypsum, desulfurized gypsum, etc.); The middle reaches are the production, processing and manufacturing of gypsum products; Downstream mainly includes construction industry, chemical industry (cement), agriculture, pharmaceutical industry and other application industries.

The upstream of gypsum is mainly raw materials and fuel power required in production and processing, mainly including natural gypsum and industrial by-product gypsum (phosphogypsum, desulfurization gypsum, etc.). 

At present, because the distribution of natural gypsum is too centralized, the proportion of high-quality resources is relatively low, and the mining is not standardized, it is easy to damage the environment and cause safety accidents, and the industrial by-product gypsum is piled up in large quantities, so phosphogypsum and desulfurized gypsum gradually replace natural gypsum and become the main raw materials of gypsum board.
