笔者从本区为砂性高岭土矿石工业类型,矿石特征,矿物成分演化规律。以及各样品可选性试验结果比较稳定分析,认为郭山高岭土采坑样及评选Ⅰ、Ⅱ号三个选矿试样具有代表性,可以分别代表本矿段二、三级品矿石,其选矿试验结果经补做砂磨试验后,可以做为矿床地质勘探阶段矿石可选性评价依据。鉴于本区矿石比较难选,其可选性试验结果还难以判定盐酸漂白就是最佳方案并有经济效益,强调需要进一步组织科研,设计及工业等部门攻关,重点突破漂白,在确定了最佳流程及漂白工艺后,再进行选矿扩大连续试验,为中间试验厂提供设计依据。
The author from the region for the sand type kaolin ore industry type, ore characteristics, evolution of mineral composition. As well as comparatively stable analysis of the test results of various samples. It is concluded that the samples of Guo Shan kaolin mining pit and the three dressing samples I and II are representative, which can respectively represent the second and third grade ore products of the mine and the beneficiation tests The result can be used as the basis for evaluation of the ore ossibility in geological prospecting stage after making up the sand test. In view of the more difficult to choose ore in this area, the optional test results also difficult to determine the hydrochloric acid bleaching is the best solution and economic benefits, emphasizing the need to further organize research, design and industrial departments and other key breakthroughs in bleaching, in determining the best After the process and bleaching process, further beneficiation is carried out to expand the continuous test to provide the basis for the pilot plant design.
