extraction of gold from its ore ny electrolysis

Gold, Silver PM's Rich Mines, Utah: EXTRACTING

The major problem with new ore bodies is in breaking the ore underground to make it accessible to the leach solution without having physical access to it. Electrowinning Metals can be recovered from solution by electrolysis, a process that is known in the extractive metallurgy industry as electrowinning.
