    1010 CRUSHING AND GRINDING (COMMINUTION) EQUIPMENT Crushing is the first step in the process of size reduction; reducing large lumps to manageable sized pieces For some processes crushing is sufficient, but for chemical processes it is usually followed by grinding to produce a finesized powder Though

  • The process design of gold leaching and carboninpulp

    After comminution the pulp is normally dilute and thickening (612% solids by mass) is performed to increase the pulp density to about 50% solids by mass This reduces the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required Many gold plants use conventional thickening with flocculant addition
