Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.

The depressing function of bacteria of LKD on diaspore and kaolinite is studied through flotation experiments, mineral ζ-electric potential and infrared spectroscopy analysis. Waste beer has better selective and depressing effects on diaspore in the range pH 2-10 than starch-like substances do. The analysis of mineral ζ-electric potential and infrared spectra shows that the bacteria of LKD ...
