Mineral Processing Wastes - Material Description - User ,
The hardness of the waste rock is determined by the rock type For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense
Iron ore pellets and Pelletizing process Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel
BENEFICIATION OF IRON ORE - National Institute of ,
Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers Iron ore sample found is a part of banded iron ore formation
