“…The authors suggested the technology for manufacture of titanium-containing ferroalloy from ilmenite concentrates and TRS via carbothermal method, using high-ash coal as a reducing agent. Possibility of use of high-ash Kazakh coal as a reducing agent was proved in several researches made by the Chemical and Metallurgical Institute specialists, and the complex alloys, such as alumosilicomanganese, ferrosilicoaluminium, ferroalumosilicocalcium, ferrochromium and ferroalumosilicochromium were obtained [13,14].…”

The object of research is the melting technology of a complex titanium-containing ferroalloy by single-stage slagfree carbothermal method using high-ash coals as a reducing agent. The ilmenite concentrate (Shokash deposit, Aktobe region, Kazakhstan), rich titanium slag, which was obtained by the scientists of the Chemical and Metallurgical Institute named after Zh. Abishev (Karaganda, Kazakhstan), as well as high-ash coal as a reducing agent were used as charge materials. Several physical-chemical characteristics of used charge materials were previously studied to carry out large-scale labour tests on the complex titanium-containing ferroalloy melting via single-stage slag-free carbothermal method. The chemical and phase composition of materials was established and two optimal compositions of the charge mixture for alloy melting were selected on their basis. The first composition contains: coal -67.35 %; rich titanium slag -26.12 %; quartzite -6.5 %. The second composition includes^ coal -66.95 %; rich titanium slag -23.1 %; ilmenite -3.3 %; quartzite -6.61 %. Tests for melting of a new complex titanium-containing ferroalloy were conducted in the ore-smelting furnace with 0.2 MVA transformer power. As a result of the tests, a batch of new complex titanium-containing ferroalloy was obtained, with the following average chemical composition: Ti -18-21 %; Si -35-45 %; Al -10-20 %; P is no more than 0.08 %, the rest is Fe. Also metallographic studies of the alloy sample were carried out in the work. The obtained alloy according corresponds in its titanium content to the brand FeTi25 (GOST 4761-91). The test results showed the principal possibility of obtaining a new complex titanium-containing ferroalloy from rich titanium slag and ilmenite concentrate using high-ash coal as a reducing agent.

The valorization of slag from the production of high-carbon ferrochrome is a challenge for ferrochrome producers. The recycling of high-carbon ferrochrome slag was explored through the smelting route to recover Fe–Si–Al–Cr alloys and reengineer the residual slag for alumina-enriched refractory material. In this research, the focus was to reduce the SiO2% and enrichment of Al2O3% in the final slag and recover the metallic value in the form of a complex alloy containing Fe, Si, Cr and Al. The manuscript consists of a thermochemical simulation of the smelting of FeCr slag followed by smelting experiments to optimize the process parameters such as temperature and the addition of coke, cast iron and alumina. An experimental investigation revealed that the maximum recovery of Si (57.4% recovery), Al in the alloy (20.56% recovery) and Al2O3 (85.78% recovery) in the slag was achieved at a charge mix consisting of 1000 g of FeCr slag, 300 g of alumina, 200 g of cast iron and 300 g of coke. The present study also demonstrated the usefulness of prior thermochemical calculations for smelting metallurgical wastes such as slag from high-carbon ferrochrome production for value creation and reutilization purposes.
