Recently, the reporter learned from the Bureau of Industry and Information Technology of Qiannan Prefecture that in order to fully implement the decision-making and deployment of the provincial party committee and the provincial government on phosphogypsum, vigorously promote the comprehensive utilization of phosphogypsum resources, and achieve a balance between production and sales of phosphogypsum, in early April this year, Qiannan The people's government of the prefecture issued the "Qiannan Prefecture Supporting the Comprehensive Utilization of Phosphogypsum Resources Rewards and Subsidies Program", and decided to arrange 40 million yuan of special funds for phosphogypsum consumption and utilization rewards and subsidies this year.

Technology is guaranteed--phosphogypsum has changed from "industrial by-product" to "resource mineral"

Phosphogypsum is a solid waste for the production of phosphoric acid, and how to digest and dispose of this industrial waste has always been a difficult problem in the industry. In the past, phosphogypsum was mainly handled by stacking, but a large amount of stacking would bring environmental safety risks.

Desulfurized gypsum is an industrial by-product gypsum obtained after the flue gas produced by the combustion of sulfur-containing fuel is desulfurized and purified by fine lime or limestone powder slurry. Its chemical composition is the same as that of natural dihydrate gypsum, mainly CaSO4·2H2O.

In April, 2022, we shipped Foaming Agent to Iran. The foaming agent is a kind of raw materials of gypsum board. In 2014, we supplied gypsum board production line to this Iranian customer, and helped them complete the installation and commissioning. Until now, the gypsum board production line has been running well and we have been supplying raw materials and spare parts to this customer these years.
