PNEUMATIC FLOTATION MACHINE Russian patent published in 2013 - IPC B03D1/24 

FIELD: process engineering.

SUBSTANCE: invention relates to concentration of minerals and may be used for processing mineral bearing ferrous, nonferrous, rare and noble metals and for cleaning effluents of solids and oil products. Proposed machine comprises aerator, tee, reactors, separation chamber, diffuser, foam settler, skimming regulator and tails discharge device. Machine is equipped with appliance for dividing homogeneous pulp flow into two jets containing, primarily, mineralised bubbles and pulp. It is composed of tube bent in circle with its top edge communicated with reactor and bottom edge connected with flat diffuser. Opposite edge of diffuser is secured at separation chamber to reduce loss of mineralised bubbles with tail (chamber) product.

EFFECT: higher yield of mineral particles.
