A simple thermodynamic analysis suggests that oil can spontaneously displace water from coal’s surface if the coal particle has a water contact angle greater than 90°. However, the clean coal products obtained from laboratory-scale dewatering-by-displacement (DbD) test work assayed moistures substantially higher than expected. These high moisture contents were attributed to the formation of wat...

It is widely accepted that the implementation of model-based predictive controllers (MPC) ensures optimal operation if an accurate model process available. In case froth flotation, modelling for control purposes a challenging task due to inherent instabilities. Most models have only focused on pulp phase rather than phase, which usually oversimplified or even neglected. Despite fact stability c...

The technological mineralogical characteristics of cesium-containing minerals in tailings were examined by means chemical analysis, the energy spectrum analysis method, and MLA (mineral liberation analyzer) to determine element content, phase associated mineral components, degree liberation, particle size, etc. results showed that samples mainly contained spodumene, quartz, feldspar, mica, othe...
