This Information Circular is published by the Minnesota Geological Survey to fulfill a part of its responsibility for providing information on the State's mineral resources. In this directory a mineral producer is defined as one who removed or mined mineral-bearing materials or substances other than water from their natural setting. Generally the producer processed the mineral raw materials into a form more suitable for marketing. The business addresses, locations of the sites of exploitation and associated plants are listed.
