Fine Grinding and Regrind Circuit Problems

Hi, A lot of this is just theorizing. We will have to try the ore out to know what sort of grind we really need. But, that said, there are several potential issues. Zinc, according to the initial feasibility test work needs to be reground in order to come up with a decent concentrate. There is no

Mineral processing

These fine bubbles have a higher kinetic energy and as such they can be used for the flotation of fine grained minerals, such as those produced by the isamill. Staged flotation reactors (SFRs) split the flotation process into 3 defined stages per cell and are becoming increasingly more common in use as they require much less energy, air and ...

Mill (grinding)

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Energy Use of Fine Grinding in Mineral Processing

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.
