The density of tar vapor and water vapor produced by coal pyrolysis is different. Different centrifugal forces will be generated when they flow through the hydrocyclone. The water vapor and tar vapor are divided into inner and outer layers. According to this phenomenon, the moisture in the tar can be removed. In this paper, a Eulerian gas–liquid two-phase flow model …

Such comprehensive research has not been undertaken in the literature although individual assessments were completed. Within the scope, copper ore, gold ore and magnetite-calcite blends were chosen as these applications are common globally. The research commenced with the experimental tests via laboratory scale air classifier and hydrocyclone.

This research primarily emphasizes on the evaluation of appropriate methods for calcite removal from a high-calcite Zonuz kaolin ore. The studied methods include sizing (screening and hydrocyclone) and flotation.

This process allowed removing impurities present in the raw material (mainly calcite and quartz), and also replacement of the original calcium exchange ions present in the clay mineral by sodium ones.

The results from the first calcite flotation test (done without a hydrocyclone step) shows a reasonable calcite recovery (92.3%) in the flotation concentrate, however the flotation concentrate contained an unacceptably high level of the uranium (29.2%). The results obtained after four hydrocyclone stages were much improved, with 94.4% of the ...
