the gold ore beneficiation line is located in zimbabwe. raw materials are processed to go into ball mill and then leached by cyanide. In the early processing stage, the gold ore is processed into a reasonable size by means of two-stage closed-circuit crushing process with jaw crusher and cone crusher, so that the ores can be beneficiated later.for ball mills operating in closed circuit, the circulation load is monitored by weighing the flow of reject material from the separator. these measures ensure you achieve optimum mill performance, giving you the quality, efficiency, safety and reliability that you need. downloads. brochures. ball mill grinding systems are either open circuit or closed circuit. In an open circuit system, the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system, coarse particles are separated from the finer product and returned for a further grinding.
