Results are provided for experimental-industrial tests of high-carbon ferrochrome smelting with partial replacement of the basic chromium ore with chromium ore briquettes produced by OJSC Donskoi Ore Mining and Processing Plant in an amount of 20–40% of the chromium ore raw material supplied to TNC Kazchrome JSC Aksu Ferroalloys Plant (Kazakhstan). These tests show that use of chromium ore briquettes has a number of technological advantages. When using briquettes instead of ore, there is a reduction in electricity consumption from 7201 to 6184 kWh/ton, and chromium extraction increases from 80.3 to 85.3%. Use of briquettes solves the problem of involving substandard chromium ore raw materials in production and improving technical and economic performance of the furnace.
