Large-scale laboratory tests for smelting medium-carbon ferromanganese using JEZDA manganese ore and SiMn17 silicomanganese fines

At present, Kazakhstan has established production of ferrosilicomanganese, while refined ferromanganese is not produced. This is primarily due to a lack of high quality feedstock, as well as a lack of theoretical and applied research into new production conditions. To address these issues we conducted large-scale laboratory tests on smelting medium-carbon ferromanganese by one-stage silicothermic method. As a result of these tests, medium-carbon ferromanganese meeting the standard grade with more than 80 % manganese content was produced
