One method relates to a method of processing mica comprising dry attrition grinding a micaceous material to produce a micaceous product having a particle size distribution such that at least about 60% by weight of the micaceous product passes through a 325 mesh screen. The dry grinding can be performed with at least one non-mica grinding media, such as a ceramic ball mill. The methods described herein can use mica from the Spruce Pine Mining District of North Carolina.
