Flotation: Recent innovations in an interesting and effective
The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up.

Muscovite | Properties, Occurrence, Uses
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.
