Abstract

FIELD: technology of zirconium. SUBSTANCE: claimed invention describes beneficiation of baddeleyite concentrate by purifying it from impurities, prior to being leached, baddeleyite concentrate is mechanically activated to give powder having "S"=3.5-4 sq.m/g and further leaching is carried out with 10-15% hydrochloric acid solution at S:L phase ratio of 1:3 to 1:5 and at temperature of 60-90 C for 15-30 minutes. On completion of leaching the phases are separated by filtration. Use of the claimed process makes it possible to reduce content of impurities to level that meets zirconium dioxide requirements, reduce the number of treatment stages, cut down energy consumption and accelerate the process. EFFECT: more efficient beneficiation process.

Изобретение относится к способам обогащения бадделитового концентрата путем очистки от примесей и может быть использовано в технологии циркония. Цель изобретения состоит в повышении степени очистки бадделитового концентрата от примесей, сокращении стадий, снижении энергоемкости и ускорении процесса. Для этого перед выщелачиванием бадделитовый концентрат механически активируют с получением порошка с Sуд = 3,5 - 4 м2/г и последующее выщелачивание проводят 10 - 15%-ной соляной кислотой при соотношении фаз Т:Ж = 1:3 - 1:5 и температуре 60 - 90oC в течение 15 - 30 минут. По окончании выщелачивания фазы разделяют фильтрованием. Использование способа позволит снизить содержание примесей до уровня, отвечающего требованиям на техническую двуокись циркония, сократить число стадий переработки, снизить энергоемкость и ускорить процесс.The invention relates to methods for enriching baddelic concentrate by purification from impurities and can be used in zirconium technology. The purpose of the invention is to increase the degree of purification of baddellite concentrate from impurities, reduce stages, reduce energy intensity and speed up the process. For this, before leaching, the baddelic concentrate is mechanically activated to obtain a powder with S beats = 3.5-4 m 2 / g and the subsequent leaching is carried out with 10-15% hydrochloric acid with a phase ratio T: W = 1: 3 - 1: 5 and a temperature of 60 - 90 o C for 15 to 30 minutes. At the end of leaching, the phases are separated by filtration. Using the method will reduce the content of impurities to a level that meets the requirements for technical zirconium dioxide, reduce the number of stages of processing, reduce energy intensity and speed up the process.
