Abstract
1. Способ переработки титановых шлаков, включающий смешивание исходного титансодержащего шлака с кальцинированной содой, спекание шихты и последовательное выщелачивание полученного спека сначала в воде с получением железо-титансодержащего осадка, а затем в солянокислом растворе с получением титансодержащего кека, фильтрацию пульпы и прокаливание осадка, отличающийся тем, что спекание исходного шлака с кальцинированной содой ведут при температуре 900°С в весовом отношении NaСО: шлак равном (0,98-1,15):1, при этом очистка от диоксида кремния осуществляется при выщелачивании спека в воде.2. Способ по п.1, отличающийся тем, что в качестве исходных переработке подвергают шлаки восстановительной плавки ильменита.1. A method of processing titanium slag, including mixing the initial titanium-containing slag with soda ash, sintering the mixture and sequentially leaching the obtained cake first in water to obtain an iron-titanium-containing precipitate, and then in a hydrochloric acid solution to obtain a titanium-containing cake, filtering the pulp and calcining the precipitate, different the fact that the sintering of the initial slag with soda ash is carried out at a temperature of 900 ° C in a weight ratio of NaCO: slag equal to (0.98-1.15): 1, while cleaning from silicon dioxide Available when leaching cake in water. 2. The method according to claim 1, characterized in that as initial processing slags are subjected to reduction melting of ilmenite.
