Beneficiation
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore. Separation based on particle density is one of the most widely used beneficiation strategies, finding application in fields as diverse as gold panning and vegetable classification. Separations based on magnetic A simple framework for developing a concept

Processing of Low-Grade Chromite Ore for Ferroalloy Production:
The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence considered as waste. Mineralogical investigation indicates the presence of chromite and quartz as major minerals with minor fuchsite and Tungsten Carbide (WC) Most of the tungsten metal powder is converted to tungsten carbide (WC) by reaction with pure carbon powder, e.g. carbon black, at 900 2200 °C in pusher or batch furnaces, Tungsten (W) Properties, Applications AZoM
