Another mining method is using water that is a byproduct of geothermal heat plants. This can solve two problems at once by creating emissions-free geothermal energy and utilizing lithium at the same time. Lithium is prolific.

Platinum mining is an incredibly labor-intensive process, which in part explains its cost. It can take 6 months or more – and 12 tons of ore – to produce a single troy ounce (around 31g) of platinum. To cut down on processing time and cost, many miners streamline their refining processes. The mines are either underground or open-pit ...

Platinum is a dense, malleable, and ductile metal with a silvery-white color. It has a high melting point of 1,768 degrees Celsius (3,214 degrees Fahrenheit), making it resistant to high temperatures. Platinum is highly resistant to corrosion, tarnish, and wear, making it suitable for use in harsh environments.
