How phosphate is mined and processed
rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 55 and 72Phosphate Rock When phosphate rock, Significant phosphate mining operations take place in many countries, with large outputs from the USA, Morocco, and China, the world total being 156 Mt in 2007 (Table 28) Table 28 Gas flow, cfm/(ton superphosphate) (hr) 250: 134: 462: 120:Phosphate Rock an overview | ScienceDirect Topics
