An adaptation of the activated sludge process is often used to remove nitrogen and phosphorus and an example of this approach is the 23 Ml/d treatment plant commissioned in in British Columbia Canada World Water The Bardenpho Process adopted is shown in simplified form in Figure 6In the comminution process there are usually a few steps in the breaking down of ore and this usually starts with a first stage or primary crushing Primary crushing is done before the ore can go through a final crush or grinding process to get the gold out This primary crushing can be by means of a jaw crusher a gyratory

What Is Comminution mosel24euMineral processing metallurgy Britannica

What does comminution mean Definition of comminution Comminution is the reduction of solid materials from one average particle size to a smaller average particle size by crushing grinding cutting vibrating or other process In geology it occurs naturally during faulting in the upper part of the Earth s crust Get Price And SupportIt is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy The primary operations are comminution and concentration but there are other important operations in a modern mineral processing plant including sampling and analysis and dewatering All
