Gold Ore Milling Process

Major ores. Typically, free milling ores are defined as those where over 90 of gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries only with the use of significantly reagents or complex pre treatment process. 1. Generally, placers, quartz vein gold ores, oxidized ores, and silver rich ores are.
