Crushing and Grinding of Ores or Pulverisation of Ores Chemistry
Aug 13, 2021Crushing and Grinding of Ores or Pulverisation of Ores : The ores generally occur in nature in the form of huge lumps. These lumps are broken into small pieces with the help of grinders or crushers so that the chemical changes which have to take place later on may become convenient. This process is called crushing, which is done by jaw crushers.
