This paper reviews the research progress about borax preparation methods. Raw material of prepa- ring borax, technological process and the morphology of borax are summarized exhaustively by means of sulfuric acid method, alkaline hydrolysis, pressure alkaline hydrolysis, carbonate-alkaline leaching, sodium roasting and atmos pheric flooding, molten sodium with atmospheric flooding, and pressure sodium roasting flooding. The advantages and disadvantages of various methods are also compared in detail. Furthermore, the development trend of borax prepara- tion is pointed out and the reference of borax preparation research is put forward.
