What is Magnesite? A Brief Overview Investing News Network

Magnesite properties and uses. Raw magnesite forms as a white, gray or brown porous crystal. In its purest forms, the mineral contains nearly 50 percent magnesium, which makes it ideal for producing magnesium for use in aluminum alloys and other applications. Magnesite is visually indistinguishable from
