Abstract
Industrial-grade phosphoric acid was produced by using mid-low-grade phosphate rock.The monocalcium chlorophosphate was separated from decomposing phosphate rock by hydrochloric acid;Researchers have been done on production and purifying of coarse phosphoric acid,which was produced by accommodating pH form monocalcium chlorophosphate,and whisking with vitriol.The experiment results showed the wet-process phosphoric acid to be industrial standard;the process is available on industrialization.
