作者运用化学分析、差热分析、电镜观察以及X射线衍射物相鉴定,对河南铝土矿的矿物形态及其在加热溶出过程中产生在压煮器内壁上的结疤进行了大量的调研。认为改造高压溶出的加热方式,是节约能耗、提高产量、降低成本和提高经济效益的可行途径。 Using chemical analysis, differential thermal analysis, electron microscopy and X-ray diffraction phase identification, the author made a lot of investigations on the mineral morphology of Henan bauxite and its scarring on the inner wall of the cooker during the heating and dissolution process. It is considered that it is a feasible way to save energy, increase output, reduce cost and improve economic efficiency by reforming the heating method of high pressure dissolution.
