METHOD FOR DEACTIVATION OF ZIRCONIUM-CONTAINING CONCENTRATE

摘要

FIELD: chemistry.SUBSTANCE: method for deactivation of zirconium-containing concentrate includes its processing with acid with heating, processing of product with water with formation of pulp, separation of purified concentrate and its drying. As zircon-containing concentrate zircon concentrate is taken. Said concentrate is milled to size 75-95 wt % of class minus 0.040 mm and subjected to processing with hydrochloric or nitric acid with concentration 5-15% at temperature 70-90°C for 2-3 hours.EFFECT: invention makes it possible to increase degree of concentrate deactivation, reduce consumption of reagents and make temperature condition milder.2 ex
