Mining on asteroids: a treasure hunt in space
Regardless of whether the asteroids' valuable elements are to be used in space or on Earth, mining will keep pace with increasing demand - because that is the only way it can remain profitable. If the market was suddenly flooded with gold, silver, and platinum, prices would plummet, and the basis for mining would disappear.

Purification of Gold by Electrolysis
In the Wohlwill's Electrolytic Process the anode consists of impure gold, 4 mm. thick, and the electrolyte is a solution of gold chloride, containing 25 to 30 grammes of gold per litre, and from 20 to 50 c.c. of concentrated hydrochloric acid per litre, according to the strength of the current. The liquid is heated from 60° to 70° C.

An Introduction to the Electrolysis Process
Many elements were discovered by Sir Humphery Davy using electrolysis. The term, 'electrolysis' was coined by Michael Faraday whose laws quantify the process. Electrolysis is primarily used in mining where an electric current is passed through a solution containing dissolved metals, causing the metals to be deposited onto the cathode.
