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

Korean Anthracite Coal Cleaning By Means Of Dry And Wet Based Separation Technologies, 2015 University of Kentucky
Korean Anthracite Coal Cleaning By Means Of Dry And Wet Based Separation Technologies, Majid Mahmoodabadi
Theses and Dissertations--Mining Engineering
Korean coals are typically high rank anthracite characterized by high ash content and difficult cleaning characteristics. The main objective of the study was to evaluate the feasibility of treating various size fractions within the coal using an assortment of physical coal cleaning technologies. Dry cleaning is preferred due to the friability of the coal. As such, three pneumatic processes were tested including Ore Sorting for the plus 10 mm material, Air Table Separation for 10 x 1 mm fraction and Tribo-electric Separator for - 1 mm fraction. The Dense Medium Cyclone is known to be one of the most efficient separation ...

Prediction Performance And Generalization Of The Empirical Estimation Of Rockmass Deformation Modulus Based On Rockmass Classification Systems, 2014 Innovative Research Publications
Prediction Performance And Generalization Of The Empirical Estimation Of Rockmass Deformation Modulus Based On Rockmass Classification Systems, Innovative Research Publications Irp India, Muhammad Tahir, Noor Mohammad
Innovative Research Publications IRP India
The deformation modulus of rock mass can either be measured using in-situ field tests or estimated empirically. However, the empirical method is an attractive and open choice for researchers to estimate the deformation modulus of rock mass economically, efficiently and accurately and many researchers have proposed empirical equations for estimation the deformation modulus of rock mass based rock mass classification systems. In this paper attempt has been made to collect and review some these published empirical equations developed so far based on Rock Mass Rating, Geological Strength Index, and Q rock mass classification systems. These empirical equations based on each ...
The Figure Of Bitu-Man, 2014 University of Nebraska-Lincoln
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, 2014 Laval University, Quebec City, Canada
A New Process To Upgrade Ilmenite To Synthetic Rutile, 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, 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 ...

History Of Innovation In Extractive Metallurgy, Fathi Habashi
People learned melting of ores to get metals since ancient times but the use of aqueous solutions for this purpose was introduced relatively recently in the Middle Ages. The most recent technology, however, came when electric current became available on commercial scale towards the middle of the nineteenth century. The present article records in general terms the development in pyro- , hydro-, and electrometallurgy
The Dark Side Of Leadership: Dealing With A Narcissistic Boss, 2014 Montana Tech
The Dark Side Of Leadership: Dealing With A Narcissistic Boss, T. W. Camm
Some of the defining characteristics of narcissists include a grandiose sense of self-importance, preoccupation with success and power, a sense of infallibility, and a supreme confidence in their ability and intelligence. Ironically, many of these characteristics are rewarded in business organizations, which may explain why there seems to be so many narcissists in management positions. Assuming we will be dealing with narcissists throughout our career, it makes sense for us to understand what makes them tick, and more importantly what we can do to work with them in a constructive manner.
Catalytic Or Thermal Reversed Flow Combustion Of Coal Mine Ventilation Air Methane: What Is Better Choice And When?, 2014 Polish Academy of Sciences - Institute of Chemical Engineering
Catalytic Or Thermal Reversed Flow Combustion Of Coal Mine Ventilation Air Methane: What Is Better Choice And When?, Krzysztof J. Gosiewski
The paper presents a comparison of the two options of reverse flow reactors destined for the utilization of coal mine ventilation air methane by catalytic (CFRR) or thermal (TFRR) combustion. It has been shown that both solutions have advantages and drawbacks. The use of the catalyst significantly decreases reactor temperature and makes the operation becomes to be autothermal for methane concentrations lower than in TFRR (even as low as over 0.06 vol.%). On the other hand when methane is combusted, particularly if average concentration is higher than ca. 0.4 vol.% the maximum temperature in the reactor appears to ...

Evidence Of The Existence Of Cathodic And Anodic Zones During The Leaching Of Minerals And Metals, 2014 Laval University, Quebec City, Canada
Evidence Of The Existence Of Cathodic And Anodic Zones During The Leaching Of Minerals And Metals, Fathi Habashi
It is accepted worldwide that the dissolution of minerals in some cases, is an electrochemical process where anodic and cathodic reactions take place. There are many parameters, such as agent concentration, that directly affect the dissolution process. The rate of leaching of minerals may differ depending on the oxygen concentration. In this paper, the existence of anodic and cathodic zones on themineral surface during the dissolution/leaching of minerals andmetals has been presentedwith some differentworks. It isworthmentioning that a good number of published papers have experimentally demonstrated the existence of anodic and cathodic areas on the mineral surface.

Geçmişten Günümüze Hidrometalurji Hydrometallurgy Over The Years*, Fathi Habashi
Thousands of years ago people had learned how to build furnaces and use fire to melt rocks and produce metals but the use of aqueous solutions for ore processing came much later, mainly at the time of the alchemists when acids and alkalies became known and used. Modern hydrometallurgy, however, can be traced back to the end of the 19th century when two major operations were discovered: the cyanidation process for gold and silver extraction and the Bayer process for bauxite treatment. Later, in the 1940s, a breakthrough came during the Manhattan Project in USA in connection with uranium extraction ...

Hydrometallurgy Over The Years (Geçmişten Günümüze Hidrometalurji), Fathi Habashi
Binlerce yıl önce insanlar, nasıl fırın yapacaklarını, ayaçları eritmek için ateşi nasıl kullanacaklarını ve metalleri nasıl üreteceklerini öğrenmelerine rağmen, cevherlerin zenginleştirilmesinde çözeltilerin kullanımı, asit ve bazların öğrenilip kullanıldığı simyacılar dönemine rastlamaktadır. Bununla birlikte modern hidrometalurjinin başlangıcı, iki önemli prosesin keşfedildiği 19. yüzyılın sonlarına dayandırılabilir. Bu prosesler, altın ve gümüşün çözündürülmesi için siyanür liç prosesi ve boksit cevherlerinin değerlendirilmesi için geliştirilen Bayer prosesidir. Daha sonra, 1940’larda, uranyum zenginleştirilmesi ile ilgili olarak Manhattan Projesi (ABD) bir dönüm noktası olmuştur. O tarihten itibaren, hidrometalurji giderek ilerlemekte ve hatta bazı pirometalurjik proseslerin yerinialmaktadır. Bu süreçte Kanada’nın, özellikle uranyum, nikel, kobalt ve çinko ...
