Understanding fine ore breakage in a laboratory scale ball
2011年2月1日 While a typical crusher might achieve 80% of the breakage rate which can be achieved in the JK Drop Weight Tester, a ball mill achieves about 30% for a similar expenditure of energy (Musa and Morrison, 2009) Hence, there is substantial potential for process improvement for a more detailed understanding of breakage within ball mills.

Understanding ore heterogeneity and effective bulk ore
1 天前 An understanding of ore heterogeneity can be assessed using drill core data, which provides metre by metre elemental assays. This paper reviews such data and assesses the grade distributions over different scales, which suggests that sufficient heterogeneity exists at mining scales to allow the potential for bulk ore sorting.
