WO2005118468A2 - Rotary kiln process for phosphoric

A direct heat kiln process for the production of phosphoric acid from phosphate ore utilizing a reductant process in combination with a carbon source, silica and heat. The process employs air control to control the burning rate of the product gasses from the kiln bed in order to control the overhead temperature in the kiln and the kiln bed temperature.

Phosphoric acid – Manufacturing process for Phosphoric acid

Phosphoric acid (H3PO4) can be produced by 3 main commercial methods: wet process, thermal process and dry kiln process. 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,

the dry kiln process phosphoric acid

Phosphoric acid is usually produced by three commercial methods, including wet process, thermal process and dry kiln process. Among these three methods, wet process is the most common route. The phosphate first reacts with the recycled phosphoric acid from the process and then mixed with sulfuric acid as a leaching agent. Then after the evaporator condensate, the gypsum separates with
