This technology involves a process modification whereby an additional process step is added prior to the ore entering the furnace. The main feature of this technique is a pre- reduction step ahead or the furnace.
Chrome ore is pelletized along with coke, binder and flux, and roasted in a rotary kiln.
This enables a substantial reduction in unit power consumption, and in pollution-abatement costs otherwise spent to control fugitive dust from handling dusty ore in the open. None were identified. V.
