Abstract:This paper presents the results of research on the development of a technology intended to process electric smelting dusts of ilmenite concentrate with the extraction of silicon and titanium and the production of products in the form of their dioxides. Dusts were processed for silicon separation using the ammonium fluoride method. The optimum conditions for the fluorination and sublimation process of silicon compounds from the electric smelting dust of the ilmenite concentrate were determined: a temperature of… Show more
“…The method is proposed [32,33] for the enrichment of titanium slag obtained after electric smelting at 1500-1600 °C or reduction roasting at 900-1000 °C, followed by separation of iron, with a composition, wt. %: TiO2 35-40; Fetotal 5-15; SiO2 5-15; MgO 2-12; MnO 1-5; CaO 2-10; Al2O3 5-15; Cr2O3 0.5-5.…”

The article discusses the main technologies for processing titanium-containing raw materials, and the advantages and disadvantages of various technological solutions. The analysis of the literature review showed that the traditional schemes for the production of titanium products are mainly focused on the use of ilmenite concentrates. In connection with the depletion of ilmenite deposits, in the near future there will inevitably be a need to switch to the use of complex ores - titanomagnetites. The obtaining of titanium dioxide from titanomagnetite raw materials with a high content of impurity components requires an individual approach for each specific deposit. It is proposed to consider the possibilities of further improvement of the development of a technological process for low-temperature (1000-1200 oC) processing of titanomagnetite concentrates with the production of pure titanium dioxide.

This article is a review of literature and patent research on the processing of lead-containing slags and their impact on life. This problem is characteristic of many countries in which industrial metallurgy is directly or indirectly present. The results of the data search allows to systematize the information available today and will undoubtedly be useful for those who deal with the problems of processing lead-containing slags. In addition, data on the influence of lead and lead-containing compounds on human life and its environment are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
