Calcination of phosphates: reactivity of calcined phosphate

1980-7-1  Although calcination produces a product of high P205 percent, the produced concentrate is less reactive than the non-calcined phosphate. The reactivity of phosphates is determined by the extent of chemical reaction of the phosphate sample with a diluted solvent. The ratio between P205 dissolved in the acid and the original P205 content is ...

Calcination parameters on phosphogypsum waste

2020-9-30  The calcination at low temperatures transforms phosphogypsum (PG) waste in a material with binder properties. This study evaluated two parameters of PG calcination: kiln residence time (1 h, 2 h, and 5 h) and temperature (120 °C, 150 °C, and 200 °C). The main objective was to find adequate calcination conditions considering PG transformation ...

Calcined Kaolin‎ Chamotte Clay AIMR

Calcination Process. Using extremely high temperatures reaching 1400 ˚C in 92m long rotary kiln to remove some unwanted elements and to alter the properties of minerals, the calcination of kaolin generally increases hardness and alters the electrical properties of the material. The process also leaves the Kaolin anhydrous (without water).
