Asteroid mining - Wikipedia
Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.. Hard rock minerals could be mined from an asteroid or a spent comet. Precious metals such as gold, silver, and platinum group metals could be transported back to Earth, whilst iron group metals and other common ones could be used for construction in space.
The Metals Mining industry is involved in extracting all metals and minerals, producing ores, quarrying stones, smelting and manufacturing metals, refining metals, and providing mining support activities. It also produces iron ores, rare earth metals, and precious metals and stones. Larger companies in this industry are vertically integrated
