As a result, biotite slice could only be used as cheap fillings of building materials. In Qinghai province of China, 45,000 t of biotite as a by-product of phosphate ore, containing ~ 20% MgO and 9–10% K 2 O were produced while processing 300,000 t of phosphate ore per year. Therefore, it attaches a great practical importance on researching ...

Magnetite Uses - Education - Micrex Development Corp

When used as the aggregate portion of a concrete mix, magnetite increases the density of the concrete to twice that of standard concrete. This so called "heavy concrete" has become a common building material in nuclear plants as well as (in brick form) for the mitigation of radiation in x-ray facilities. Beyond that, however, heavy concrete is ...
