Method for separating particulate materials |
摘要 |
Particulate materials of different density are separated from one another by placing them in non-reactive liquefied gas of intermediate density whereby the lighter material floats and the heavier material sinks. A pressure field may be established in the liquefied gas to enhance the particulate separation process. The method is especially suited for separating and removing oxide and other particulate contaminants from metal and alloy powders.
