Abstract
The granulometric characteristics of the precipitate were investigated, and the chemical composition of the solution for complex processing of iron-nickel concentrate was established. The filtering process was carried out using a model of a chamber and chamber-membrane filter press. Separation of the suspension was implemented using chambers with a depth of 10 and 20 mm. It was established that washing is possible only with the use of a weak HCl solution due to the need to inhibit the development of hydrolysis of iron salts in the pores of the sediment. A scheme for optimizing the water balance of the washing process is proposed. Initial data are formulated for designing a filtration section of a complex processing plant for iron-nickel concentrate. Criteria for process automation are defined.
