The organic binder CMC (carboxymethyl cellulose) was modified with nano-CaCO3 and then used to improve the compressive strength of preheated and fired pellets. SEM (scanning electron microscope) data on modified CMC (CCMC) showed that the nano-CaCO3 compactly coated the CMC surface. Studies of preheated and fired pellets’ compressive strength revealed that the CCMC has excellent bonding properties...
In this study, selective magnetic coating was employed to separate pentlandite and serpentine. The surface properties of minerals with and without reagents and magnetite were characterized by zeta potential measurements, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM). Zeta potentials showed that the surfaces of serpentine...
