Phosphate and How Florida Was Formed

Florida’s phosphate mining today accounts for about 80% of the phosphate used in the United States, as well as about 25% of the phosphate used around the world. The Florida that we know today and the phosphate buried in its earth is a relatively recent product of geologic processes

Natural radioactivity assessment of a phosphate fertilizer

2014-1-1  Reported values of 238 U in rock phosphate range from 1.0 to 5.7 Bq/g (Barisic et al., 1992, Guimond and Hardin, 1989, Heijde et al., 1988). These phosphates are largely used for the production of phosphoric acid, fertilizers and hence phosphate fertilizer industries are considered to be a potential source of natural radionuclide contamination.

Mining Chemicals International Mining

2011-6-1  Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this month’s im-mining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at the players, challenges, and future horizons for the sector.

Review on Beneficiation Techniques and Reagents Used

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
