摘要: A process is disclosed for producing high brightness kaolin from ore containing silica, other types of clays, minerals such as ilmenite micas, feldspars and various metal silicates well organic matter. The consists sizing, a double floatation step, magnetic separation, leaching oxidative brightening steps. This novel combination conventional unit operations in particular the use step to remove quartz trace that interfere with achieving optical kaolin.
