Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Metal processing. Grains in metals tend to grow larger as the metal is heated. A grain can grow larger by atoms migrating from another grain that may eventually disappear. Dislocations cannot cross grain boundaries easily, so the size of grains determines how easily the dislocations can move.

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.

All other ore types can be mined with all types of ore mining lasers or strip miners. Ore variants . Each asteroid type has three further subtypes that yield more (+5% / +10% / +15%) minerals when reprocessed. Otherwise they are identical in every way to their base ore, and are found in the same regions, but in lower quantities, except for the +15% variant which is only found in moons.
