Phosphate Rock. When phosphate rock, phosphorus concentrate, and fluxes are smelted in an electric arc furnace under temperatures of 1400–1500°C (2552–2732°F), molten slag is formed and tapped out from the furnace and goes through an air-cooling or water quenching process. On the other hand, the quality sources of phosphate rock are

2013-5-7 Here are some basic points to keep in mind: Whilst we all use P2O5 content as an index of quality it doesn't mean much in terms of the potential effect of the rock phosphate on crops. For example, consider a rock phosphate with quite low total P 2 O 5 of 25% and citric acid soluble P of 15%. 1,000 kg rock phosphate yields 16 kg plant available P.

Rock phosphate. Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops.
