霓石与铁矿物的分离是浮选领域中复杂的课题之一。本文以矿物晶体化学和络合物化学理论为基础,并借助于俄歇电子能谱和穆斯堡尔效应等现代分析技术,通过大量的试验,在霓石和赤铁矿的晶体构造、表面特性和浮游性之间找到了联系。研究表明,磨矿过程霓石表面受铁离子的污染,是它与铁矿物用通常的方法难以分离的主要原因;粗晶霓石表面含钙量偏高是其用阳离子捕收剂浮选时,浮游性不高的原因之一。为此,本文提出了络合浸蚀浮选法。亦即先用有机络合剂(酒石酸、EDTA 等)改变霓石的表面特性,再进行浮选。用该方法以油酸钠或月桂胺作捕收剂,分离多种人工混合矿获得了成功的结果.
The separation of aegite and iron minerals is one of the more complex topics in the field of flotation. In this paper, based on the theory of mineral crystal chemistry and complex chemistry, and with the help of modern analytical techniques such as Auger electron spectroscopy and Mössbauer effect, through a large number of experiments, the crystal structure, surface properties of hematite and hematite Found contact with the planktonic. The results show that the surface of the zeolite in the grinding process is contaminated by iron ions, which is the main reason that it is difficult to separate from the iron minerals by the usual methods. The high calcium content on the surface of the coarse grained zeolite is obtained by cation collector flotation When the buoyancy is not high one of the reasons. To this end, the paper proposed a complex etching flotation method. That is, the organic complexing agent (tartaric acid, EDTA, etc.) is used to change the surface characteristics of aegirine and then flotation. Using this method, sodium oleate or lauryl amine as collector, the separation of a variety of artificial mixed ore obtained successful results.
