On the Issue of Obtaining Iron Sulfate Crystals from Titanomagnetite Concentrate
https://doi.org/10.18412/1816-0395-2026-5-16-19
Abstract
In order to process titanomagnetite concentrate (Khibiny massif), optimal technological regimes were selected: temperature 80 °C, СH2SO4 concentration 50%, solid-to-liquid ratio 1:3, stirring intensity 400 min-1, duration 180 min. Iron sulfate was obtained from productive solutions, from which a coagulant for the removal of suspended solids was prepared. It was established that the efficiency of suspended solids removal using the coagulant reached 97.3%. A technological scheme for concentrate processing with the production of iron sulfate crystals was proposed.
