Therefore, the pilot flotation equipment must provide a high level of flexibility to conform the flowsheet requirements. When done properly, the pilot test can significantly increase the test work accuracy, setting a more reliable basis for the industrial scale process design and equipment selection.

The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.

Within flow chart (a), the reasons for increased flotation activity of oxyhydryl collectors with (sim C_{12}) are associated with the lack of penetration of reagent molecules into the pores of coal [31, 32]. Within flow chart (b), an increased activity of these collectors is explained on the basis of dependence .

Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation …

The actual flotation process is a complex, multi-factor coupling separation process. The bubble size is synergistically affected by the frother, collector, slurry properties, mechanical energy input, and air flow rate in the flotation cell. The effect of multi-factor coupling on the bubble size should attract sufficient attention.
