Crushing develops more efficient particle breaking, avoiding fine particles, and optimizing energy consumption. The liberation step is the grinding process and consumes most of the energy in a mineral processing plant. The liberation size gets smaller every day, and the milling operation must be constantly optimized.

Most ores, however, are made up of hard, tough rock masses that must be crushed before the valuable minerals can be released. In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or 0.4 to 0.6 inch, in diameter), crushing is done in stages. In the primary stage ...

Mining & Milling Centerra Gold. A gyratory crusher reduces the ore to minus 15-20 centimetres. The ore is then fed to a coarse ore stockpile from which it is reclaimed for grinding, first to a semi-autogenous ("SAG") mill and then to a ball mill, which together reduce the grain size to 80% passing 140 microns.
