Industrial minerals in Manitoba

Total mineral production in Manitoba has averaged C$1 billion over the past ten years. Industrial mineral production has comprised almost 10% of the total, with more than half coming from the aggregate sector. In southeastern Manitoba, tantalum, spodumene and amblygonite concentrates, cesium and rubidium ores, cesium formate, dimension stone and sphagnum peat moss are produced. Gypsum, high-calcium limestone and lime are produced in the Interlake area. Early industrial mineral production consisted of tools and implements, salt and pottery. Historical production has included: salt, building stone, aggregate, lime and dolime, lignite coal, gypsum, natural and Portland cement, calcium bentonite, brick, light-weight aggregate, caustic soda and soda ash, and silica sand. Future industrial mineral production may come from reactivated quarries, pits and wells or from new producers of current commodities. Newproducts may include: stainless steel master alloy, silicon metal, titanium and magnetite, lithium carbonate, float-plate glass and ferrosilicon, "marble" dimension stone, magnesium metal, potash and kaolin.
