Comprehensive Processing of Basalt together with Magnetite Concentrate in Order to Obtain Ferrous Alloy and Calcium Carbide

Shevko V. M., Karataeva G. E., Badikova A. D., Tuleev M. A., Uteeva R. A.

Archives of Foundry Engineering

Vol. 20, iss. 4

41--54

This article is devoted to basalt reprocessing together with magnetite concentrate in order to obtain ferrous alloy and calcium carbide. The studies have been based on thermodynamic simulation and electric smelting in arc furnace. The thermodynamic simulation has been performed using HSC-5.1 software based on the principle of minimum Gibbs energy. The blend was smelted in arc furnaces. On the basis of the obtained results of combined processing of basalt, it has been established that under equilibrium conditions, the increase in carbon content from 36 to 42 wt % of basalt and concentrate mixture makes it possible to increase the aluminum extraction into the alloy up to 81.4%, calcium into calcium carbide – up to 51.4%, and silicon into the alloy – up to 78.5% [...]
