12.8: Mining and Mineral Use
An ore is a rock that contains minerals with useful elements. Aluminum in bauxite ore (figure 1) is extracted from the ground and refined to be used in aluminum foil and many other products. The cost of creating a product from a mineral depends on how abundant the mineral is and how much the extraction and refining processes cost. Environmental ...

Quality requirements of iron ore for iron production
Therefore, the TI of iron-bearing materials should be > 95% + 6.3 mm and the RDI < 12% − 6.3 mm, as well as CCS > 225 kg. More fines in the shaft furnace decrease the bed permeability, leading to nonuniform gas flow and temperatures in the shaft as well as difficulties in injecting the reducing gas through the bustle.
