- Mica milling operation
Mica is ground dry to yield finely divided mica particles prior to forming a sheet. A single sheet of uniform thickness is formed at one time by pouring a colloid mixture of the ground mica, water and a colloid agent onto a mesh screen. Vacuum means and a hydraulic press are used to complete the formation of a sheet. The sheet also includes a resin binder.

To determine the extent of grinding obtainable, a 60-minute grinding test was made in the 5-inch-diameter, stainless steel attrition grinder using a leonardite-water feed pulp density of 50 percent solids and a 2.5-to-1 weight ratio of sand to leonardite. The grinding medium used was minus 14- plus 28-mesh Ottawa sand.

Milling operation at a mild speed of 300 rpm produced a highly effective adsorbent for heavy metal ions removal. This mild milling operation induced the phase transformation of phlogopite from trigonal to monoclinic, accompanied with significant releasing of anions and cations which was defined as self-dissolving phenomenon.
