Impurities in phosphate rock. - CAB Direct

Impurities in phosphate rock. Phosphate rock is one of the more abundant of the world's natural resources, but each deposit has its own characteristics which must be taken into account when processing. As the quality of phosphate rock available for processing declines, the P2O5 content goes down and the content of impurities tends to rise.

Phosphate Rock Mosaic Crop Nutrition

Most phosphate rock is used to produce soluble P fertilizers, but some is used for direct application to soil. While phosphate rock can be a valuable source of P for plants, it’s not always appropriate for direct application. Its suitability depends partly on naturally occurring mineral impurities, such as clay, carbonate, iron and aluminum.

Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation. By comparison, the average phosphorus content of sedimentary rocks is less than 0.2%. The phosphate

Processing of phosphate rocks containing less P20 5and more impurities results in less product, higher processing costs and less potential profit. In order for a phosphate rock to be suitable for a wide range of processing options, the R20 3 (Fe203 + AhO))1P20 5ratio must generally be below approxi- mately 0.10.
