A Novel Mineral Flotation Process Using Thiobacillus

Flotation is known as one of the methods which can separate minerals on the basis of differences in the mineral surface properties. In the flotation process, mineral particles with hydrophobic surfaces attach to air bubbles generated at the bottom of a flotation column and float up to form a froth at the top of the column.

Research of novel process route and scale-up based on oil

With the scaling up of the flotation column, all of the oil removal efficiencies were more than 95%, so the oil-water separation flotation column has good stability and oil removal efficiency. The flotation column using the coalescence-airflotation-carrier preferential adsorption process provides a new and good way to treat the oily sewage.
