Special bacteria are sometimes used as part of this process. After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid

Much of the time people mine and then refine their ore into minerals and either sell the minerals or use them in industry, but some people choose to just sell ore as without good refining skills much of the value of the ore is lost in refining waste. When mining to sell ore, your profit is calculated in isk/m³.
Ore is a deposit in the Earths crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.
Asteroids contain a finite amount of ore. If mining an asteroid, the mass of the asteroid will be reduced by the amount of ore extracted. There is no need to use any scanners to find out the ore concentration for asteroids, it's enough to be close to it or on it. Storage
