Abstract

The conditions for precipitation of iron arsenate from acidic solutions containing Pb, Fe, Cu, Zn and As are investigated. The following is defined: the relative concentrations of iron and arsenic, the effect of acidity, as well as the degree of deposition of arsenic and iron on the duration of the process. It is shown that the value of pH 4, in the ratio of Fe:As=5:1 and in the process duration 1.5 hours, the solution precipitates out about 90% As and 24% Fe. Residual arsenic in solution after precipitation is less than 0.1 g/L. The obtained results can be used in the purification of hydrometallurgical solutions.
