Extractive Metallurgy | Introduction to Chemistry

Extractive Metallurgy | Introduction to Chemistry

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores (leaching).

Metallic Minerals Processing

process of separating valued minerals from the matrix rock. The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require

 · Abstract The recovery of major components of bauxite residue by carbothermic reduction at 1550–1750 °C and subsequent slag leaching in a Na3CO3(aq) solution is studied. Iron recovers primarily to pigiron and lime is added to tune the calcium aluminate slags towards the highly leachable mayenite phase. The concentration of aluminum in the leachate correlates well with the occurrence of ...

Chapter 4: Mining waste

The amount of tailings generated is dependent on the ore grade, (proportion of valuable minerals in the ore). For example, if the cutoff grade in the ore is 1 % Copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore ...
