Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and the rain.

Asteroid mining Wikipedia

Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including nearEarth objects. Hard rock minerals would 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. Difficulties include the high .
