| titleOfInvention | RECOVERY OF PRECIOUS METALS USING A THIOCIANATE LIXIVIANT |
| abstract | A mineral material containing precious metals is subjected to an acid leaching with thiocyanate to dissolve the precious metals in the form of precious metal thiocyanate complexes. The thiocyanate leaching solution feed may include a high molar ratio of ferric iron to thiocyanate. The precious metals can be separated from the solution of leaching of prenated thiocyanate, such as by transferring precious metals from the precious metal-thiocyanate complexes to precious metal-cyanide complexes and then loading the precious metal-cyanide complexes onto a material adsorbent. The remaining cyanide in the thiocyanate leaching solution can be converted to thiocyanate for further leaching of precious metals. |
