TENORM: Fertilizer and Fertilizer Production Wastes ...

Before phosphate ore is turned into fertilizer or other products, it is transformed into either phosphoric acid (through a wet process), or elemental phosphorus (through a thermal process). This processing concentrates NORM in the waste products, transforming them into Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM).

Phosphate Fertilizer - an overview ScienceDirect Topics

Phosphate fertilizers have been important sources for contamination of agricultural soils with cadmium and likewise sludge from sewage treatment plants has added metals (especially cadmium has caused concern) to farmland when used as soil amendment. The addition of copper to, for example, the feed of pigs may lead to copper concentrations in the pig manure that are high enough to exceed the ...

Phosphate Fertilizer - an overview ScienceDirect Topics

Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or ‘wet process’, in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 2H 2 O):

Phosphoric acid – Manufacturing process for Phosphoric acid

Wet process is by far the most common route and the acid can be used in phosphate fertilizers production (DAP, MAP, SPA). Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals, pharmaceuticals, detergents, food products, and other nonfertilizer products. The last method, using a rotary kiln, is a promising alternative because of its ...

A weak phosphoric acid (40-55%) is produced from the reaction of PR with sulfuric acid, using a wet- process. The obtained phosphoric acid is then used in the production of a series of liquid or solid fertilizers. The most important ones are single and triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP). Usually the plants are using flexible process technologies, allowing the ...
