A vertical column pneumatic separator was modified to improve its separation performance. A branch column was installed at the center of the main column, which created a bypass flow and changed the flow rate of the main column before and after the br

The velocity of a particle in water depends on both its size and specific gravity. For separation methods, in which separation is done by the difference of particle velocities, such as a jig, a cyclone, or a shaking table, separation by size or speci

A method for calculating the degree of mineral matter liberation by the sink–float separation data of coal was studied. The mineral composition was estimated by norm calculation using the results of elemental analyses of sink–float separated coal

Interaction forces between a bubble and a particle are critical for various industrial processes that handle colloidal dispersions, especially for froth flotation. Therefore, it is fundamentally important to understand the surface force between a bub

In many industrial processes, surfactants are used to control the dispersion and coagulation of particles in aqueous solutions. Especially, surfactants have critical effects in flotation separation. To investigate the effects of surfactants to the su

A method to disintegrate photocopied or laser printed waste office paper by weak agitation and using kerosene as a toner softening agent was investigated. Under the conventional method using only sodium hydroxide, 3.8% of toner was liberated from pap

A method for disintegrating waste office paper using kerosene was reported in our previous paper, which achieved almost a 100% liberation of toner from paper fibers. The liberated toner must be completely separated to realize effective deinking. Rece

Recently, a new method for deinking waste officer paper by magnetic separation after hetero-coagulation of magnetic and non-magnetic toner has been reported. The selection of flocculants which can produce large and strong coagulates is very important
