Phase equilibrium and aeration rate of countercurrent flotation
LIU Huan-sheng
OU Ze-shen
Abstract：Countercurrent flotation process is studied by using phase equilibrium principle. The new concept about minimum ratio between gas and liquid, and about minimum aeration rate are put forward. The conclusion is obtained that flotation aeration rate is directly proportional to the product of flotation concentrate quantity in flotation pulp and concentrate recovery meeting technological requirements, and is inverse proportional to the concentration of flotation concentrate in air bubbles with concentrate. The conclusion can provide theory base of design on aeration rate of countercurrent flotation column.
