Experimental Techniques, in 1987. He is Fellow
of the Geological Society of America and of the Mineralogical Society of America. Dr. Barnes has been awarded 12 endowed lectureships, four U.S. patents for novel scientific processes, including two 2013 patents for the “Acid-Cure Slurry”, a simple, cost-effective method to control Acid Rock Drainage (ARD). ARD or acid mine drainage refers to the acidic water that is created when sulphide minerals are exposed to air and water and, through a natural chemical reaction, produce sulphuric acid.
He was also Director of the Ore Deposits Research Institute at The Pennsylvania State University for eight years. Geology of Ore Deposits is one of the few special periodicals devoted to metallic and nonmetallic mineral resources and the conditions of their formation and distribution. Ore deposits are minerals or an aggregate of minerals from which
a valuable constituent, especially a metal, can be profitably mined or extracted. They are formed by lateral secretion and by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults. An ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.
