A refining process for non−ferrous melt and equipment thereof. The process, including an adsorbing purification by letting a purified gas pass through the non−ferrous melt, is characterised in that, a vaccume is applied above the non−ferrous melt while the gas adsorbing refinement is undergoing to form a reduced pressure drawing the molten metal. The equipment is composed of a non−ferrous melting and treating device and a vaccum device, the vaccum device therein is connected with the space above the melt in the non−ferrous melting and treating device. The said melting and treating device may be single−chamber, multi−chamber, or chamber−free constitution. The refining process of present invention makes it possibles either for meeting the requirements of environment protection, or of the achievement of high efficiency, energy saving and low consumption. The refining equipment of present invention can make the said process more easily to be carried out.
