Phosphate mining is one of the world’s largest mining industries in terms of value of production and annual tonnage. However, papers on phosphate mining and mineral processing are usually rare at most of the major mining as well as mineral processing conferences, both nationally and internationally.  Beneficiation of Phosphates has been established as the only conferences of international significance focusing on phosphate mineral processing.

Phosphate ore is not only the source of an essential nutrient (P) for plant growth, but it also contains substantial elements critical to developing green energy for the future. Uranium in phosphate deposits account for 88% of the unconventional U resources, while rare earth elements (REEs) in phosphate deposits represent hundreds of years of current world demand for these vital elements.  Beneficiation of Phosphates VII will devote at least two sessions to comprehensive recovery of P and other values from phosphate ore, such as U, REEs, F, Th, and I.

Phosphate mining and processing generate two major waste streams, waste clay and phosphogypsum, in huge quantity.  These wastes are becoming significant financial and environmental liabilities for the industry, and present a public perception problem as well.  Naturally, utilization and treatment of these wastes will be one of the focuses of this conference, with two sessions tentatively scheduled, one on waste reduction and another on waste utilization.  Other important issues to be discussed include flotation efficiency, dolomite separation techniques, on-line analysis and process control, novel processing techniques and machinery, and hydrometallurgical processes.

In summary, Beneficiation of Phosphates VII will cover the following topics:

  • Flotation and other physical separation techniques
  • New reagents development and testing
  • Beneficiation of carbonaceous phosphates
  • Processing of low-grade phosphates
  • Analysis and process control
  • Equipment and process development
  • Advances in phosphoric acid manufacturing
  • Recovery of rare earths from phosphate
  • Recovery of uranium, thorium and other values from phosphate
  • Phosphogypsum utilization
  • Sustainable development and the environment.
