Determination of the concentration of MIBC in coking coal flotation
Abstract. This paper presents a novel method to measure the concentration of methyl isobutyl carbinol (MIBC), a widely used frother in coking coal flotation. It is based on the specific interaction between MIBC molecules and a formulated liquid mainly comprising cyclodextrin and pyrene. The method involves mixing the formulated liquid …

Examination of NaCl and MIBC as bubble coalescence …
It can readily be seen that MIBC, a surface active agent, is much more efficient at stabilising bubbles with concentrations a few orders of magnitude lower than found in NaCl solutions. In the concentration range used in flotation (10 −4 M, 10 ppm), MIBC offered limited resistance to coalescence with bubble pairs. Conclusions

Flotation Frothers
Flotation Frothers – Frothing Agents. The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air.
