前言贵州铝土矿资源丰富,主要分布在林歹、小山坝、长冲河、燕垅、麦坝等主要矿区。矿石的主要工艺类型为一水硬铝石型,其特点是低铁高铝硅比。根据贵州铝矿组成的特点。目前仍采用传统的拜耳法工艺生产。由于Al_2O_3的溶出效果受到多种因素的影响,和铝土矿的组成、晶型结构和溶出条件的不同,虽然国内外不少研究工作者,曾针对上述课题作过大量的实验和研究,但结论尚不一致,目前还很难用比较简单的数学式对溶出过程作出概括的说明。我们的实验研究结果表明,对于
Preface Guizhou bauxite rich in resources, mainly in the forest evil, Xiaoshanba, Changchonghe, Yan 垅, Maiba and other major mining areas. The main type of ore for the diaspore type, which is characterized by low iron high silicon ratio. According to the characteristics of Guizhou aluminum mines. Currently still using the traditional Bayer process production. Due to the influence of many factors on the dissolution of Al 2 O 3 and the different composition, crystal structure and dissolution conditions of Al 2 O 3, many researchers at home and abroad have done a lot of experiments and studies on these topics. The conclusion is not consistent, it is still difficult to use a relatively simple mathematical formula elucidation of the dissolution process to make a general statement. Our experimental findings show that for
