Four Methods Analysis of Gold Mineral Processing LinkedIn
For gold-bearing quartz vein ore, it is generally ground to 60-70%-200 mesh; while for sulfide mineral gold-bearing ores, flotation enrichment is often used, and the concentrate is re-ground to 90Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, The Grinding Fineness- the Factor Affecting Gold Leaching
