Kaolinite Clay Beneficiation Process: Kaolin Processing
The kaolin processing plant designed by JXSC has a high degree of mechanization, which can reduce labor and reduce the labor intensity of operating staff. The entire beneficiation process uses less water, effectively protects groundwater resources, and reduces a large amount of waste gas emissions, which promotes the protection of the ecological environment.

Physical separation of iron ore: magnetic separation
Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% Fe).While magnetite ores are naturally …
