Annual output of 240,000 tons of cement clinker! Guizhou Phosphogypsum Co-production Acid Project Will Be Put into Production Soon

September 2026, Kaiyang, Guizhou. Shengwei Group's 500000 tons/year phosphogypsum resource comprehensive utilization project for sulphuric acid co-production of new materials will officially start trial production. As early as 2022

, Shengwei Group completed a 500,000-ton phosphogypsum sulphuric acid production project. However, due to the collaborative operation mode based on the sulphur-burning sulphuric acid plant, the sulphuric acid production system was deeply bound to the sulphur-burning sulphuric acid production system and could not operate completely independently, which restricted the release of production capacity.

In 2026, Shengwei Group decided to carry out upgrading and transformation-to separate the acid-making system from the original 600000 tons/year sulfur-based acid-making system and build a new system that operates independently. The total investment of the project is 60 million yuan, mainly for the construction of sulfuric acid production plant, circulating water station and related supporting facilities. After the completion of the

transformation, the project can comprehensively utilize 500000 tons of phosphogypsum, produce 200000 tons of sulfuric acid and 240000 tons of new materials (cement clinker ).
