jun 14, 2018 using ball mills to extract raw gold from ores. placer mining and lode mining are very different. whereas placer gold has been released from within the rock and is generally free from any significant matrix, lode gold presents different challenges. while gold may be present in ore, it must somehow be released for proper extraction.
oct 10, 2016 At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill, it leads to mill overload. In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption. drum mills have one grinding chamber (short and
ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills is typically vol.-% ore and 25% steel. the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

feature of ball mills is their high specific energy consumption. mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. therefore, it is most disadvantageous to use a ball mill at less than full capacity.
consumption in metal ore milling plants the grinding process in ball mills is notoriously known to be highly inefficient: only to of the inputted electrical energy serves for creating new
the mechanization of the continuous type ball mill is high, and the unit energy consumption is less. for example, the graphite ball mill and the iron ore ball mill have excellent energy-saving performance.
