开发新技术是解决与铁矿选矿有关的环境问题的有效途径。综合性矿物学研究有助于选矿过程的改进。笔者与IPKON研究所的专家们一起研究开发一种电化学的方法,以改善制备用于湿法磁选的矿粉的性质并研究了使用电化学方法前后样品的性状。采用扫描电镜(SEM)技术研究矿物颗粒表面,发现其在絮化作用中的差异;偏极化曲线的测定可以揭示磁铁矿、赤铁矿和假象赤铁矿等矿物表面的不均等电化学过程;X-射线分析和穆斯堡尔谱数据亦可确定电化学处理前后矿粉样品成分的变化。所研究样品的磁性,在采用该方法前后样品的对比揭示其在:磁粘滞性(Svo)、磁饱和场的破坏(Hcr)、磁化率(χ)、及磁化强度(Is)等参数的相应增大。
Developing new technologies is an effective way to solve the environmental problems associated with iron ore beneficiation. Comprehensive mineralogy research contributes to the beneficiation process improvement. I worked with experts at the IPKON Institute to develop an electrochemical method to improve the properties of mineral powders for wet magnetic separation and to study the behavior of samples before and after electrochemical methods. Scanning electron microscopy (SEM) was used to study the surface of mineral particles and the difference in flocculation was found. The determination of polarization curve could reveal the unequal electrochemical behavior of mineral surfaces such as magnetite, hematite and hematite X-ray analysis and Mossbauer spectroscopy data also confirm changes in the composition of the mineral samples before and after electrochemical treatment. The magnetic properties of the investigated samples before and after using this method revealed that the magnetic susceptibility (Svo), magnetic saturation field (Hcr), magnetic susceptibility (χ), and magnetization A corresponding increase.
