Refractory grade bauxite properties make calcined bauxite ideal for refractory & abrasive products. Great Lakes Minerals, LLC (GLM) has been in the business of providing high quality refractory and abrasive industrial minerals for two decades. Founded in 1999, GLM is located at the Greenup Boyd County River Port Industrial Site in Wurtland, Kentucky, directly adjacent to the Ohio River, near the converging borders of Kentucky, Ohio and West Virginia. GLM accepts the delivery of raw materials, which includes refractory bauxite, from barges directly to our plant along the Ohio River. GLM is conveniently located for low-cost shipping to most regions of the country in which refractory bauxite and brown fused alumina is widely used.

Great Lakes Minerals is a supplier of refractory grade bauxite. Our refractory bauxite is sourced from two countries, China and Guyana.  Our pursuit of high quality begins at the mines in these two countries where we accept only high grade bauxite, continues with quality checks at the U.S. borders and again at the point of delivery to our plant. We understand the importance of refractory bauxite in providing critical heat and strength insulation and our customers know that when they purchase refractory bauxite from Great Lakes Minerals, they can be confident that their work will be accomplished as needed for the job.

Refractory bauxite properties such as high alumina and density and low iron make calcined bauxite the ideal raw material with which to manufacture refractory and abrasive products.  As refractory bauxite suppliers, our customers use this product for a variety of purposes in the refractory industry.
