Hi Jamie: Per our recent conversation, the shoring system is 12 feet from the face to centerline of track. Even though this is less than the 15’ feet called out in C&M Agreement, this reduced clearance is only temporary (no more than 6 hours) and not an issue. During the construction of the shoring wall, a work window will be established to eliminate train traffic on the adjacent track for that short duration. Once installed, the shoring system will be at the same elevation or lower than the top of rail, making the 12 feet clearance moot. Any questions, please ask. Thank you, Jason L.

  • ABB's Long History of Making Mining Operations More Efficient
    ABB’s long history of making mining operations more efficient Innovative technologies have improved productivity for mining since the 1890s ABB’s comprehensive automation and power delivery at Boliden’s Aitik copper concentrator plant is the latest chapter in the company’s rich history of improving the operations of all types of mines and ore processing plants. The company has provided solutions that make mining operations more efficient, productive and safe for almost 120 years, since delivering the first drives and controls for a mine hoist at the Kolningsberget iron mine in Norberg, Sweden, in 1891. Drives and controls help mine hoists operate more efficiently and consistently as they haul tons of ore from lower levels of a mine to the surface. Over the years, ABB has made other breakthroughs in mine hoist technology including hydraulic disc brakes, controlled braking and Rope Oscillation Control, all of which have made mine hoists more reliable and safer to operate. ABB has delivered more than 600 new hoists and modernized hundreds of existing plants. A mine hoist delivered around 1930 by ASEA, a predecessor of ABB, to the Zinkgruvan zinc mine in Sweden is still in operation today. Pioneer of gearless mill drives ABB pioneered the development of gearless mill drive (GMD) systems, which are giant motor and drive systems that power ore-crushing mills. They are more reliable and energy efficient than traditional mill drive systems, and increase mill productivity. ABB delivered the world’s first gearless machine drive to Lafarge Cement in France in 1969. The 6.4 megawatt (MW) equipment is still operating today.

  • Charcoal As an Alternative Reductant in Ferroalloy Production: a Review
    processes Review Charcoal as an Alternative Reductant in Ferroalloy Production: A Review Gerrit Ralf Surup 1,*, Anna Trubetskaya 2 and Merete Tangstad 1 1 Department of Materials Science and Engineering, Norwegian University of Science and Technology, 7491 Trondheim, Norway; [email protected] 2 Department of Chemical Sciences, University of Limerick, V94 T9PX Castletroy, Ireland; [email protected] * Correspondence: [email protected]; Tel.: +47-934-73-184 Received: 12 October 2020; Accepted: 3 November 2020; Published: 9 November 2020 Abstract: This paper provides a fundamental and critical review of biomass application as renewable reductant in integrated ferroalloy reduction process. The basis for the review is based on the current process and product quality requirement that bio-based reductants must fulfill. The characteristics of different feedstocks and suitable pre-treatment and post-treatment technologies for their upgrading are evaluated. The existing literature concerning biomass application in ferroalloy industries is reviewed to fill out the research gaps related to charcoal properties provided by current production technologies and the integration of renewable reductants in the existing industrial infrastructure. This review also provides insights and recommendations to the unresolved challenges related to the charcoal process economics. Several possibilities to integrate the production of bio-based reductants with bio-refineries to lower the cost and increase the total efficiency are given. A comparison of challenges related to energy efficient charcoal production and formation of emissions in classical kiln technologies are discussed to underline the potential of bio-based reductant usage in ferroalloy reduction process. Keywords: charcoal; pyrolysis; bio-based reductant; ferroalloy industry; kiln 1.

  • 1. Introduction Ferrosilicon Smelting Is a Continuous Process Carried out In
    Arch. Metall. Mater., Vol. 61 (2016), No 1, p. 265–270 DOI: 10.1515/amm-2016-0050 B. MACHULEC*,#, W. BIALIK** COMPARISON THE PHYSICO-CHEMICAL MODEL OF FERROSILICON SMELTING PROCESS WITH RESULTS OBSERVATIONS OF THE PROCESS UNDER THE INDUSTRIAL CONDITIONS Based on the minimum Gibbs Free Enthalpy algorithm (FEM), model of the ferrosilicon smelting process has been presented. It is a system of two closed isothermal reactors: an upper one with a lower temperature T1, and a lower one with a higher temperature T2. Between the reactors and the environment as well as between the reactors inside the system, a periodical exchange of mass occurs at the moments when the equilibrium state is reached. The condensed products of chemical reactions move from the top to the bottom, and the gas phase components move in the opposite direction. It can be assumed that in the model, the Reactor 1 corresponds to the charge zone of submerged arc furnace where heat is released as a result of resistive heating, and the Reactor 2 corresponds to the zones of the furnace where heat is produced by electric arc. Using the model, a series of calculations was performed for the Fe-Si-O-C system and was determined the influence of temperatures T1, T2 on the process. The calculation results show a good agreement model with the real ferrosilicon process. It allows for the determination of the effects of temperature conditions in charge zones and arc zones of the ferrosilicon furnace on the carbothermic silica reduction process. This allows for an explanation of many characteristic states in the ferrosilicon smelting process.

  • Reduce Ductile Iron Processing Costs Through The
    Nodulizing and Inoculation Approaches for Year 2000 and Beyond - Part 1 by Dr. R. L. (Rod) Naro ASI International, Ltd. – July 30, 2001 Original Paper presented June 15, 2000 DIS Meeting, Wichita, Kansas Abstract: Nodu-Bloc, a new iron-magnesium briquette, offers ductile iron foundries a powerful alloy that can be used to replace traditional magnesium ferrosilicon (MgFeSi) as well as other magnesium containing master-alloys. Controlled laboratory tests show that Nodu-Bloc can replace up to 50 weight percent of MgFeSi. Field trials with Nodu-Bloc confirm these results and show that Nodu-Bloc replacement of MgFeSi can provide significant cost savings. Foundries converting to Nodu-Bloc will experience reduced melting costs because less MgFeSi is consumed, less steel and pig iron is required in the charge and far greater levels of foundry returns can be utilized. Foundries can easily save up to $10 or more per ton on molten ductile iron processing costs by incorporating Nodu-Bloc technology. Introduction: Since the commercialization of ductile iron in 1948, foundries have used numerous methods to introduce magnesium into molten cast iron. Figure 1 lists some of the approaches and techniques used over the years. Although some of these processes gained a brief following, and some have even been used successfully, most have fallen out of favor because of numerous shortcomings. Today, the majority of ductile iron castings made throughout the world are produced using ladle-metallurgy practices with MgFeSi alloys. It is estimated that MgFeSi alloys are used in 65 percent of all ductile irons produced worldwide. In the United States, MgFeSi alloys account for an estimated 75 percent of ductile iron production.

In this paper, the method and the result of Analytical Hierarchical Process is presented, shown on a case study – Open pit Drmno, as one of the largest lignite mines in Serbia. The analysis included 6 criteria and two alternatives were applied as Variant 1 and Variant 2. The results show that the suitable mining system for this case study – open pit Drmno is Variant 2. Keywords: mining systems, mining equipment, excavation, analytical hierarchy process. INTRODUCTION In a micro scale Drmno deposit does not differ from the regional characteristics in the number of The purpose of this paper is to rank mining plies for main coal III Seam. The III Seam and its systems in open pit Drmno as one of the most two plies are present in 60% of drill holes, while in stable mining system for production of lignite the rest of 40% drill holes layering is present with for electricity in power plant in Serbia.
