Method for recovering precious metals from precious metal-bearing materials such as ore and tailings |
摘要 |
A method for recovering precious metals such as gold and silver from precious metal-bearing materials that include other solids comprises treating the precious metal-bearing materials with an aqueous, basic solution having a pH in the range of about 12 to about 14 for a time sufficient to suspend the precious metals in substantially free form in the solution, followed by recovery of precious metals from solids and from the solution by known methods.
