CMC
is used in mining industry as pellet binder and flotation inhibitor. CMC is a
component of the binder for mineral dust shaping and meanwhile the binder is an
indispensable ingredient for pellet production. It can improve the properties
of wet pellet, dry pellet and calcinated pellet. Due to its good binding
property and pellet forming property, the green pellet with CMC has excellent
antiknock performance, high compressive strength and dropping resistance. It
can also increase the grade of pellet. CMC is an adjusting agent in floating
selection process, it is used as the silicate gangue inhibitor, controlling the
lead in the separation process of copper and lead, sometimes it is used as
dispersant for mineral mud.
1. Applications in pellet
*Good pellet forming and water controlling property
*pellet is changed from hydrophilicity to hydrophobicity.
*Good dispersibility and high strength of wet pellets
*No pellet distortion
*Good strength of dry pellets
*increase of the pellet compression strength
*High cracking temperature and strong in controlling and releasing the water
inside the pellet
*Homogeneous distribution of pellet size
*Smooth pellet surface
*Good metallurgy performance
2. Applications in flotation
*Good water-solubility and strong inhibiting ability
*Improve the grade of finished ore and get better specifications in ore
selection
*Reduce the use of other agents and cut down the consumption of raw materials
*Mainly used as silicate gangue inhibitor, and inhibit lead in separation of
copper and lead, and sometimes worked as slime dispersant.
