Only two of these varieties, muscovite, and phlogopite, have received any general application in the industries, and have constituted therefore the major part of present mine recoveries.As regards extent and availability, and their more comprehensive uses, indispensable to the electrical industry as a vital factor in its enormous expansion, the varieties of muscovite, having the same chemical composition and varying only in physical characteristics, are the basic factors at the present time in domestic mica mining and manufacturing.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
