Minerals Research Lab Reports

The Minerals Research Laboratory is a world leader in research, development, and implementation of mineral processing techniques. The MRL is part of the North Carolina State University College of Engineering, under the management of the NC State Industry Expansion Solutions.

Introduction

This page lists public mineral beneficiation reports prepared by the Minerals Research Laboratory (MRL). These reports and publications are organized chronologically from oldest to youngest. By listing these reports here, it is hoped these will provide a bridge from exploration to bench-scale and pilot plant beneficiation studies to assist the minerals industry. These reports also provide a wealth of information on North Carolina’s mineral resources.

Many of the public reports are available for free download directly from the web site, by clicking on the report title. We are scanning and uploading the reports as time allows, so reports that have not been uploaded yet are available only by request. Use the contact page to request any report not available on-line; they are all free of charge.

The MRL also conducts research and provides services under contractual agreements with industry and private companies. Reports pertaining to these studies are confidential and are not available to the public without written permission of the sponsor.
