Identifying the rock you wish to remove is the first part. Bedrock isn't all the same and the various types of matrix on crystals can be quite stable. Sometimes more stable than the crystal itself, as in the case of staurolite in mica. As a general rule, the most commonly dissolved matrix rocks are calcium-based.

The vast difference in the structure of a sand mass and mica mass is illustrated in the loosely dumped dry density of the sand and mica used in this study. The unit weight of the dry sand was 16kN/m3 in comparison to a mere 2kN/m3 for the dry mica. The significant conclusions from early parts of the work may be summarised as

Mica is mostly brown, green, grey and red in colour, with a hardness of 2.5-4 and a specific gravity of 2.7-3.3. Mica is very flakeable and can be divided into very thin lamellae, transparent to translucent, with a glassy lustre. Mica has good heat resistance during heat treatment and can withstand high temperatures. Chemical Properties
