Abstract
In this paper, the environmentally friendly recycling systems are introduced. The environmentally friendly mineral resource extraction, recycling and environmental technologies that utilize the multi phase flow are classified into different kinds of multiphase. In the mineral resources extraction, grinding, wet separation, flotation, magnetic separation and electrostatic separation are introduced. As for recycling technologies, short time crushing, jigging, heavy dense media separation, sink and float separation using magnetic fluid, fluidized bed, liquid-liquid separation, magnetic separation, triboelectrostatic separation are discussed. Water purification and recycling resources are also listed as the environmental technologies.
