在矿业领域中有许多有关磨矿的学派,这些学派都认为他们自己的磨矿方法是最可行的,然而磨矿的方法是千变万化的。某些粉碎的方法包括多段破碎,而且只有一段磨矿;但其它的方法中破碎可能是并不很重要的,而且磨矿过程可能会很复杂。本文先对九种最通常的粉碎回路进行分析,然后评述了一个半工业试验的结果。在该试验中镍矿石经过四种不同的方法粉碎,然后给入常规的浮选回路进行处理。 There are many schools of grinding in the field of mines that all think their own grinding methods are the most viable, but grinding methods are ever-changing. Some crushing methods include multiple crushing and only one grinding; however crushing may not be important in other methods and the grinding process can be complicated. This article first analyzes the nine most common crushing circuits and then reviews the results of a semi-industrial test. In this test, nickel ore is ground in four different ways and then fed to a conventional flotation circuit.
