Quick and efficient.

Superior Minerals a sister company of Linwood Mining

Superior Minerals Company is a producer of high-quality mineral fillers and granules located in the Twin Cities right off of the Minnesota river. Our rock is mined at our sister company—Linwood Mining and Minerals—and then barged to our unloading facility in Savage, Minnesota.

We process high-calcium limestone into specified granules and powders for use in animal feed, roofing shingles, fluidized-beds, plastic, and a variety of other commercial and industrial applications. We also have the ability to load and unload barges due to our location on the Minnesota River.
