摘要： A process of producing 99% plus titanium dioxide product by using conventional and microwave heating and leaching of the titanium compound feedstock using acid and oxidants. The solid residue from the leaching is used to produce the high quality titanium oxide by froth flotation. Hydrochloric acid can be recovered by multi-stage evaporation. The process can be modified to produce nano-size titanium dioxide product.

摘要： The invention concerns a vortex machine modified to intensify the vortex in the machine by installing inlet fans in addition to the main fan and modifying the configuration of the machine. Additional intensification of the vortex is achieved by introducing microwaves into the vortex machine. The vortex machine has a vortex tube, an inlet tube to the vortex tube at the inlet end, a feed inlet to the vortex tube between the inlet end and an outlet end and a fan rotor at the outlet en to draw air in a vortex through the vortex tube. An inlet fan in the inlet tube adapted to force air into the vortex tube. These modifications and additions achieve commercially viable capacities of the vortex machine in drying, grinding and process applications.

摘要： A liquid vortex separator including a vortex tube (16) with an impeller (13) in the feed end to impart a rotational motion to liquid within the tube, a feed cylinder (12) connected to the vortex tube by a reducing cone (14). The separator has a separating cone (17) at the outlet end, an annular collecting ring (18) for heavy solids and a liquid discharge pipe extending axially from the separating cone. A feed tank (31) and circulating stream arrangement ensures operation of the system at varying feed rates. The liquid vortex separator may also be fitted with microwave generators (40), electrodes (51)powered from a DC source or magnets (60) to produce desired effects or chemical reactions in the material being processed through the liquid vortex separator.
