        CIRCULAR ECONOMY

        Huiyun Titanium makes full use of the advantages of Yunfu's resources and advantages of industrial clusters. Through technology grafting and process improvement, the products or wastes produced in the production process can be directly recycled and enter the reproduction link, forming “Pyrite → Sulfuric Acid → "Titanium Dioxide → Gypsum, Cement" is a complete circular economy operation mode that realizes the comprehensive utilization of resources.


        Huiyun Titanium circular economy model is to use high-grade sulfur concentrates rich in local pyrite resources, and then use sulfur concentrates as raw materials to process high-purity, high-value-added chemical reagents; sulfuric acid waste heat 2.2MPa of steam produced by the boiler can be used for supporting titanium dioxide projects, which can save 50,000 tons/year of coal consumption for titanium dioxide production; use titanium dioxide and sulfuric acid waste by-product acidic wastewater, use stone powder and calcium carbide slag to neutralize industrial gypsum, For the local cement factory as an additive. Yunfu annual production of 20 million tons of cement, gypsum additives required 600,000 tons / year, while the company's production of 220,000 tons / year of gypsum is still far from meeting the local cement plant demand for gypsum. At the same time, the production of large amounts of waste titanium dioxide in the production process of ferrous sulfate heptahydrate has some impact on the environment, Huiyun Titanium Industry through the combination of dynamic drying and flash calcination technology, production of monohydrate ferrous sulfate 80,000 tons / year, As a feed additive sale, it solved the problem of large pollution, difficult handling and high transportation costs for ferrous sulfate heptahydrate, and truly realized comprehensive utilization and turning waste into treasure.
