Management Challenges In Nurturing A Safe Work Environment, T. W. Camm 2015 Montana Tech

Management Challenges In Nurturing A Safe Work Environment, T. W. Camm

Mining Engineering

As engineers, we are trained to use logical, rational problem solving to insure our mines operate at maximum efficiency. We tend to use the same technical approach to design safety into all mining systems. This works well for machines, but not so much for the human component. Recent insights in the field of behavioral economics provide useful ideas for addressing the fact that we are driven by emotions more often than by rational thought. Understanding the nonrational aspect of human behavior is an important piece of any safety system design.

The Dispersion And Selective Flocculation Of Hematite Ore, Howard James Haselhuhn III 2015 Michigan Technological University

The Dispersion And Selective Flocculation Of Hematite Ore, Howard James Haselhuhn Iii

Dissertations, Master's Theses and Master's Reports - Open

Iron ore is one of the most important ores in the world. Over the past century, most mining of iron ore has been focused on magnetite (Fe3O4). As the name suggests, magnetite is magnetic in nature and is easily separated from gangue (unwanted) minerals through magnetic separation processes. Unfortunately, the magnetite ore bodies are diminishing. Because of this, there has been a recent drive to pursue technology that can economically separate hematite (Fe2O3) from its gangue minerals as hematite is a much more abundant source of iron. Most hematite ore has a very small liberation size that is frequently less ...


Pilot Scale Demonstration And Evaluation Of Innovative Non-Deslimed Non-Classified Gravity-Fed Hm Cyclone, Yumo Zhang 2015 University of Kentucky

Pilot Scale Demonstration And Evaluation Of Innovative Non-Deslimed Non-Classified Gravity-Fed Hm Cyclone, Yumo Zhang

Theses and Dissertations--Mining Engineering

Coal preparation plants are required in some cases to produce a high-grade product using a low specific gravity cut-point. For these situations, a second higher gravity separation would be desirable to generate a mid-grade product that can be utilized for electricity generation thereby maximizing coal recovery. A study was conducted to evaluate the potential of achieving efficient separations at two different density cut-points in a single stage using a three-product dense medium cyclone. Variations in density cut-point and process efficiency values were quantified as a function of the feed medium density, feed medium-to-coal ratio, and feed pressure using a three-level ...

The Figure Of Bitu-Man, Paul Royster

Faculty Publications, UNL Libraries

The ominously imposing figure in the above illustration is “the Syncrude bird deterrent device, locally known as ‘Bitu-man’.” He stands (or stood—the original image was from the late 1970s) in the tailings pond of the Syncrude Canada Ltd. oil sands mining operation along the Athabasca River near Fort McMurray in northeastern Alberta. That operation surface mines (i.e., strip mines) bitumen-impregnated sand, processes it with hot water and steam, and discharges the liquid effluent or “tailings” into a pond covering roughly 3000 hectares (11 square miles). (Google Map coordinates: 56.9°N, -111.3° W). Residue bitumen collects on ...


A New Process To Upgrade Ilmenite To Synthetic Rutile, Fathi Habashi 2014 Laval University, Quebec City, Canada

A New Process To Upgrade Ilmenite To Synthetic Rutile, Fathi Habashi

Fathi Habashi

Ilmenite occurs in black sand at the mouth of great rivers as in India, or as massive deposits like in Quebec Province in Canada. It is unsuitable for processing into pigment or for metal production because of its high iron content and its low grade. Pyrometallurgical and hydrometallurgical methods have been developed to cope with this problem which resulted in the production of two commercial products that became known as synthetic rutile and Sorelslag. Attempts are also underway to produce TiO2 pigment directly from ilmenite. This report presents a newly developed process called the Magpie process, which enables the production ...


Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen 2014 Minnesota State University, Mankato

Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen

Journal of Undergraduate Research at Minnesota State University, Mankato

The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at depth could have significant economic impact on the mining industry in northern Minnesota. To evaluate the likelihood of finding more high-grade iron ore deeper underground, it is important to determine the source of the fluids ...
