Industry Overview - Phosphate rock is a key upstream raw material, with yellow phosphorus and phosphoric acid as important intermediates, and downstream products primarily used in agriculture and industry [3][4] - The phosphate chemical industry chain includes phosphate rock and sulfur as upstream materials, with phosphoric acid produced through various processes [4] Resource End - China ranks second globally in phosphate rock reserves, with significant deposits located in Yunnan, Hubei, Sichuan, and Guizhou [6] - The total phosphate rock reserves in China are approximately 3.69 billion tons, with a low average grade of 16.85%, indicating over-exploitation and resource wastage [9][10] Production Capacity - Domestic phosphate rock production is the highest globally, but there has been a trend of decreasing output since 2018 [7] - Major phosphate rock producers include Hubei, Guizhou, Yunnan, and Sichuan, with a total production capacity of 1,450 million tons by Yuntianhua and 950 million tons by Guizhou Kaipin [11] Product Demand - Approximately 60% of phosphate rock is used for producing phosphate fertilizers, with a growing demand for high-efficiency and high-value utilization [13] - The main phosphate fertilizers include monoammonium phosphate (MAP) and diammonium phosphate (DAP), which are essential for crop growth [14][15] Phosphoric Acid Production - The phosphoric acid industry in China has a low concentration of production capacity, with a total capacity of 618 million tons, including 270 million tons of thermal phosphoric acid and 348 million tons of wet phosphoric acid [25] - The wet phosphoric acid production process is gaining traction due to its lower energy consumption and environmental impact compared to thermal methods [24][27] Environmental Considerations - The production of yellow phosphorus is characterized by high energy consumption and pollution, with limited new capacity being added [18] - The treatment and utilization of by-products such as phosphogypsum and fluorosilicic acid are becoming critical for the sustainable development of the phosphate chemical industry [32] Future Outlook - The industry is expected to focus on expanding the production capacity of wet phosphoric acid and functional phosphate salts, moving towards a more refined and specialized manufacturing approach [36] - The demand for feed-grade phosphate salts is anticipated to grow due to the increasing scale of aquaculture and livestock farming in China [37]
