Various milling processes that reduce phosphate rock particle size to increase solubility can provide low-cost alternative approaches to the production of water-soluble P fertilizers. However, finely ground phosphate rock has been shown to insufficiently improve phosphate rock effectiveness (Ibrahim et al. 2010 ).

Since the energy crisis in the 1970s, most Florida phosphate companies capture the heat released in the burning of sulfur and production of sulfuric acid and use it to produce steam. The steam is used to produce the heat required to concentrate the phosphoric acid and also to produce electricity to run the plant.
