In a standard design of a mineral processing plant, comminution tests play a significant role [17]. A geometallurgical model of a deposit provides an image of the resource's variation, identifies the spatial geometallurgical domains of the orebody, and determines the response of the ore rocks to the beneficiation plant.

Muscovite is a common mineral that belongs to the mica group. It is a silicate mineral that is characterized by its thin, sheet-like structure. Muscovite is composed of potassium (K), aluminum (Al), silicon (Si), and oxygen (O) atoms arranged in sheets, and it is known for its excellent cleavage, which allows it to be easily split into thin, flexible sheets.
