MEI Blog: A brief history of classification in grinding circuits

2014/08/15· The future is high frequency screens". This has led, unsurprisingly to a few comments on the use of hydrocyclones and screens in milling circuits. Prof. Lynch has been in touch this morning by email, and asks me to publish this short technical note, which he entitles Classification – the enigma in mineral processing.
