RESEARCH INTO PREPARATION OF PHOSPHORIC ACID AND AMORPHOUS ON THE BASIS OF LOW-GRADE MAZI-DAG PHOSPHORITE (TURKEY) AND WASTE SULFURIC ACID

In contrast to real technology with the use of results obtained from laboratory studies, the combined technological circuit for manufacture simultaneously in one installation extractive a phosphoric acid both amorphous is developed on the basis of phosphorite and waste a sulfuric acid. The description of process carried out on the new technological circuit, technological regime parameters have been submitted, quality indicators of the received product determined. Its reveled that the suggested technological circuit allows to reduce expenses for manufacture and improve quality of product.
