  • How to use comminution processes for reducing the ore

    Also, we use the attrition scrubbing process with comminution, in the case of agglomerated ore, which can be naturally or due to a long time remaining such as a stored ground ore or a tail. The screening process is useful to control the product size of crushing, and also for engineering and optimization purposes. Moreover, it allows protecting crusher machines in the first stages.

    Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It 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 operationsОнлайн-запрос
