Industry experts explore the development and utilization of medium and low-grade phosphate rock and other resources to get out of the "deep lane"

As we all know, China's high-grade phosphate rock resources are limited and soluble potassium resources are poor, but medium and low-grade phosphate rock resources are abundant

Zhang Fusuo, academician of the Chinese Academy of Engineering, said: "Whether it is from the sustainable aspect of protecting China's phosphate mines and potash mines, or in terms of reducing agricultural application and increasing efficiency, and improving soil, the innovation and transformation of the fertilizer industry has reached a critical moment, and we should be alert

Chen Mingliang, chief engineer of the Fertilizer Institute of Shanghai Chemical Industry Research Institute Co.

Shi Lin, a professor at South China University of Technology, said that removing heavy metals from low-grade phosphate rock and combining with potassium feldspar to produce a phosphorus-containing mineral soil conditioner is the core of advanced technology and industry

According to Liu Wenzhi, Institute of Energy Conservation and Environmental Protection, Shanghai Jiading Advanced Technology Innovation and Breeding Center, Chinese Academy of Sciences, China's phosphate rock resource reserves are about 3.

The forum was chaired by Qi Zhaoying, Deputy Secretary-General of the Fertilizer Special Committee of the China Chemical Society and Secretary-General of the Soil Health Branch of the China Chemical Enterprise Management Association
