Kinetics of flotation - CONCENTRATION OF MINERALS

Flotation kinetics (from the Greek Kinētikós - driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R = f (t).It allows a quantitative description of the ...

Dow offers a range of glycol ether, polyglycol and alcohol-based frothers designed for a wide range of system conditions and requirements, from fine to coarse particle flotation.

The Recycling Process | DPDA

Paper recycling is a large scale, multi-step process with the objective to recover the paper fibers, and often other paper components such as mineral fillers, and use them as a raw material to produce new paper. Depending on the types of paper sourced for recycling and the final application, each recycling system is optimized accordingly.
