2018 10 21ensp;0183;ensp;Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to

2018 10 16ensp;0183;ensp;An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements. The grade or
Results available to date indicate that gold and silver mineralization from the Tonopah project are amenable to recovery by cyanide leaching. Test work has been completed on both fully oxidized and sulfide samples, with little difference noted in recoveries.
