摘 要: 鎂是地殼中含量較為豐富的金屬元素，可用于助劑、添加劑與結構功能材料，有廣闊的應用潛力。金屬鎂進入工業(yè)化生產(chǎn)，主要經(jīng)歷了電解法與熱還原法，并分別衍生出各種電解法工藝與熱還原法工藝。本文綜述近20年國內(nèi)外鎂冶煉技術的研究現(xiàn)狀，詳細介紹一些典型的新型鎂冶煉技術工藝，其中部分工藝方法已進入中試與產(chǎn)業(yè)化示范階段，為我國原鎂冶煉技術的發(fā)展起到了示范引領作用。最后，針對主流生產(chǎn)工藝存在的問題以及當前新工藝的研究現(xiàn)狀，提出原鎂冶煉技術發(fā)展的建議與思路。

Abstract:Magnesium is a rich metal element in the earth''''s crust, which can be used as additives and structural functional materials. The industrial production of magnesium mainly has experienced electrolysis and thermal reduction, and various electrolysis and thermal reduction processes were derived. This paper summarized the research status of magnesium production technology at home and abroad in recent 20 years, and introduced some typical new magnesium production technologies in detail. Some processes have entered the pilot and industrial demonstration stage, which plays a leading role in the development of original magnesium smelting technology in China. In view of the problems existing in the mainstream production process and the current research status of the new process, the suggestions and ideas for the development of the magnesium production were put forward for reference.
Key words: magnesium production; silicothermic process; carbothermic process; magsonic process
