| Abstract: | The conversion rate of phosphate rock of P205 80 kt/a phosphoric acid plant in Three Cycles Branch Company is only 96.01%. For improving the conversion rate and reducing production cost, with the analysis on the decomposition theory of phosphate rock by sulfuric acid and production status, some measures are taken from extraction process, equipment, operation and production management etc. After modification, the conversion rate of phosphate rock is 97.18%, the phosphorus recovery rate in extraction tank is increased, the economic benefit is remarkable. |
