Bitumen—sand interaction in oil sand processing

12/1/1995· As a result, the following procedure, as illustrated in Figure 1, was adopted to quantify the bitumen-silica attachment. The Teflon plate (6 mm x 6 mm) was coated with a layer of bitumen ( < 0.5 mm thick) and was mounted on the electromechanical device. The bitumen-coated plate was submerged in the test solution containing a silica sand bed.

Gravity Separation- Principle, Uses and Applications

The gravity separation process is used to separate ore minerals. It is an old dressing technic for ore concentration. However, it is useful only for granular mixtures down to 0.5 mm, which means as fine as the liberation size of valuable minerals, their recovery by gravity separation is less efficient. Silica sand
