Silica sand washing process. Washed and graded. The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is the opposite. This phenomenon is especially obvious in quartz sand containing a large number of clay minerals. Therefore, the quartz sand ore before the selection is carried out.
Feb 22, 2000 Milling of the slurry is typically accomplished in a media mill, a ball mill or sand mill. This step reduces or eliminates the agglomerates in the base pigment, which are formed during oxidation or calcination. The media milling before treatment reduces the intensity of final milling, which is needed to produce optimum pigment properties.
