NATURAL EMERY

Natural Emery is a very hard rock type used to make abrasive powder. It largely consists of the mineral corundum (aluminum oxide), mixed with other species such as the iron-bearing spinels hercynite and magnetite, and also rutile (titania). Industrial emery may contain a variety of other minerals and synthetic compounds such as magnesia, mullite, and silica. However natural emery is mostly made of Corundum. Translucent brown Corundum and Emery are the most common forms of Corundum. These are fairly common and when ground up, they are the most favorable abrasives. The industrial term "emery" describing corundum abrasives is derived from the variety Emery which is mined for abrasive use. Emery is used on surfaces to make them more resistant. Emery grains can be used as hard aggregates for anti-skid and non-wear flooring. This type of flooring is most useful in areas like warehouses with heavy forklift traffic, workshops where oil is spilled and heavy objects fall now and then, hospital..
