Automation and Robotics in Mining and Mineral Processing

The aim of a mineral processing operation is to concentrate a raw ore for the subsequent metal extraction stage. Usually, the valuable minerals are first liberated from the ore matrix by comminution and size separation processes (crushing, grinding, and size classification), and then separated from the gangue using processes capable of selecting the particles

Energy Use of Fine Grinding in Mineral Processing - Springer

2013年12月18日  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
