“…The evidence is conclusive that sulfide minerals of iron and copper can be successfully oxidized and leached with autotrophic bacteria (2,3,7). The solubilized copper is recovered from the leachates by precipitation with iron.…”

“…This article reports some laboratory experiments which show that autotrophic bacteria found in the leaching streams from the waste rock dumps in Bingham Canyon, Utah, can oxidize molybdenite (M0S2), and also show the effect of other sulfide minerals which occur with molybdenite in ore deposits on the oxidative process (7).…”

“…In 1958, I was approached by a colleague, James R. Dunn from the Department of Geology at RPI, who wanted information on some bacteria he had just read about in the literature that were able to promote the oxidation of pyrite and some other metal sulfides. His questions to me were in reference to Thiobacillus ferrooxidans, much later renamed Acidithiobacillus ferrooxidans, which had been implicated in the generation of acid drainage from bituminous coal mines in Appalachia by the work of Colmer, Temple, Hinkle, and others (Colmer & Hinkle 1947, Colmer et al 1950, Temple & Colmer 1951, Temple & Delchamps 1953, Leathen et al 1953. At the time that Dunn first posed his questions to me, I was unfamiliar with these organisms.…”

This is a memoir relating how the author became a geomicrobiologist and how he practiced his specialty. Born in Germany and receiving his early schooling in Berlin, he completed his secondary education, followed by college and graduate school training, after emigration to the United States in 1940. After attaining a PhD degree in 1951, he spent his entire professional career as a faculty member of the Department of Biology at Rensselaer Polytechnic Institute (RPI) in Troy, New York. He was introduced to geomicrobiology in 1959 by a question from a colleague in the Department of Geology at RPI concerning the recent discovery of acidophilic ironoxidizing, autotrophic bacteria in acid coal mine drainage. This led him to investigate bacterial interaction with metal sulfides, Mn(II) and Mn(IV) on land and in the sea, chromate, and bauxite; to teach a course in geomicrobiology; and to write a textbook on the subject, first published in 1981.

“…These are normally disposed of in surface waste deposits such as tailings dams and heaps or backfilled into disused workings leading to the risk of environmental pollution [15][16][17][18][19][20][21]. Of particular concern in the case of wastes generated from sulfide-bearing hard rock ores and coal is the formation of acid rock drainage on exposure to air and water [22][23][24]. Acid rock drainage (ARD) causes water pollution and soil sterilization [25,26].…”

The mining and minerals beneficiation industries produce large volumes of waste, the land disposal of which can lead to harmful environmental emissions and a loss of valuable resources. Globally, researchers are developing technologies for recovering valuable minerals and converting mine waste into a resource with market value. However, university-developed technological innovations to long-term environmental problems can be difficult to transfer to the mining industry. This paper focuses on the barriers and enablers to technology transfer in the South African mining industry using the valorization of coal processing waste as a case study. Data and information derived from interviews with relevant experts and published literature were used to gain a better understanding of the landscape of waste valorization technology implementation. Results indicated that financial considerations and demonstration of technical feasibility will be vital in determining the success of technology transfer, as will a changing perception of waste and its value within the sector. Original equipment manufacturers (OEMs) and boutique waste processors were identified as potential commercial partners for further development and commercial implementation of university-developed waste valorization technologies within the mining sector.
