Nickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal with a relatively high melting point and excellent corrosion resistance. Nickel is commonly found in the Earth's crust, but it is typically …

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 …
