The Ohio Aggregates & Industrial Minerals Association is the trade association in Ohio that represents all of the state's mining operations, except coal. These commodities include mostly construction materials, both natural and manmade, such as aggregates (which are sand, gravel, slag, and crushed limestone, dolomite, and sandstone), salt, clay, shale, gypsum, industrial sand, building stone, lime, cement, and recycled concrete.
