平果铝土矿溶出性能的初步研究
杨重愚1,龙远志1,陈谦德1,唐向琪1

(1.有色冶金系)

摘 要: 本文研究了各种因素对平果铝土矿中氧化铝溶出率的影响,比较了平果矿和国内几个主要矿区铝土矿的溶出性能,提出了这些矿石的x光衍射谱、差热曲线和红外光谱的测定结果以及某些赤泥样品的电子显微镜观察结果。对平果矿的溶出性能,针铁矿在溶出时的行为,添加石灰以及Na2SO4和NaCl的作用进行了讨论。

PRELIMINARY INVESTIGATION ON THE DIGESTIBILITY OF PINGGUO BAUXITE
杨重愚1,龙远志1,陈谦德1,唐向琪1

1.有色冶金系

Abstract:Pingguo bauxite is a kind of diasporic ore. It contains high iron oxide,most of which is present as geothite. Some influencing factors on the extraction of alumiuum oxide from Pingguo bauxite were investigated. In orderto compare the digestibility of Pingguo bauxite with that of some other main domestic deposits, digestion tests were carried out under the same conditions. The characteristics of these ores were also studied by x-ray diffraction, differential thermal analysis and infra-red spectroscopy. Some samples of the red mud were observed with electron microscopy. In the present paper the experimental results of the tests and the main conclusions are given.The digestibility of Pingguo bauxite, the behaviour of its geothite duringdigestion as well as the effects of CaO, NaSO4 and NaCl as additions in the digestion liquor are also discussed.
