Ecology for China

The project adopts the advanced technology recognized by the Ministry of Environmental Protection – the clean production process of titanium dioxide by the sulfate method. It has formed a circular economy system of titanium-phosphorus-sulfur-iron-calcium, achieving the maximization of resource utilization through the integration and coupling of the circular economy. The acid-making system provides the necessary sulfuric acid and steam for the production of titanium dioxide, using advanced medium and low-temperature heat recovery technology. The medium-pressure steam generated is used for waste heat power generation, and the low-pressure steam generated after power generation is used for the production of titanium dioxide, achieving the maximum and graded utilization of thermal energy. The waste acid from the production of titanium dioxide is concentrated by the tail gas of the furnace after the furnace, and the titanium dioxide system is reused and sold to surrounding enterprises for use, and a portion is used to produce granular export superphosphate and other chemical products. The production of titanium dioxide byproduct ferrous sulfate is mixed with sulfur iron ore, and the iron powder residue produced is sold to steel mills. The mining sector will be built into a first-class benchmark mine in the country with integrated mining, selection, and recharging.
