Introduction to Mineral Processing -

The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site. Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite. Particle Size

From ore to steel – ArcelorMittal

The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon.
