Grindability of Various Ores

During the last few years, one of the great problems in the milling of all ores has been that of grinding. This subject involves not merely the cost of the operation, but also the selection of the proper degree and character of grinding to yield the best metallurgical results on the given ore. Considering the diversity of machinery, one is led to wonder at the variety of grinding methods

A process for grinding coal or ores containing metal values comprising carrying out said grinding in a liquid medium and with a polyelectrolyte grinding aid comprising N-(sulfoalkyl)-derivatives of acrylamide and methacrylamide, said grinding aid being dispersible in the liquid medium, and being present in an amount effective to provide increased grinding efficiency.

Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013 Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget.

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.
