本文综合介绍几个有关耐火粘土和高岭土除铁试验的成果。用于这些试验的高梯度磁选机,是由克留吉—纳卜卡非金属矿业研究设计院(ICPM S N)设计和制造的。研究人员的目的在于通过他们的试验,从各种成因的某些粘土矿物中,确立降低其铁含量的可能性,以及确定磁选工艺的最佳操作参数,即磁场强度、悬浮液浓度、流体添加剂的类型和用量、悬浮固体颗粒在分选机缝隙内的通过速率等。 This article presents several achievements on refractory clay and kaolin iron removal tests. The high-gradient magnetic separator used in these tests was designed and manufactured by the Krugeri-Nabucco Institute of Non-metallic Mining Research and Design (ICPM S N). The researchers aim to establish the possibility of reducing their iron content in some clay minerals of various origins by their experiments and to determine the optimum operating parameters of the magnetic separation process, namely the magnetic field strength, the concentration of the suspension, the concentration of the fluid The type and amount of additives, the rate of passage of suspended solids within the separator gap, and the like.
