A PROCESS FOR PRODUCTION OF FERROSILICON FROM BANDED HEMATITE QUARTZIT

摘要

A process for the production of ferrosilicon from Banded Hematite Quartzite comprising the step of: subjecting banded hematite (BHQ), low reactive coal, quartzite and pet coke to the step of crushing; mixing banded hematite quartzite (BHQ), low reactive coal, quartzite and pet coke in the ratio ranging between 1:1:0.25:0 to 1:0:1.33:1.53; introducing the said mixture of raw materials in submerged arc furnace having a temperature range from 1700 to 1900°C; tapping the materials into the moulds.
