This paper incorporates the three pillars of sustainability—economic, environmental, and social dimensions—into a supply chain. A multiobjective programming model which jointly minimizes costs, emissions, and employee injuries in a supply chain is first constructed. Using the weighted-sum approach with weights setting by the analytic hierarchy process (AHP), the model is solved
Iron Ore: Penalty elements in iron ores dilute the overall ore grade and reduce the ore-processing efficiency. Niton analyzers can determine the composition of the iron ore and other base metal deposits (Fe, Cu, Pb, Zn, Ni, Co).

LKAB is an international and high-tech mining-and minerals group that mines and upgrades the unique iron ore of northern Sweden for the global steel market. Sustainability is core to our business and our aition is to be one of the industry’s most
They include deteriorating ore characteristics and poor mineralogical information on deeper ores, water quality and availability, steel wear and increasing power costs. Rapidly declining productivity, sustainability and environmental factors, new taxes, mining industry global skill set shortages, to name but a few, must also be considered.

In collaboration with the Swedish iron ore producer LKAB he currently focusses on the process mineralogy of exploration targets near Kiruna. Besides his research he is responsible for teaching bachelor and master students in economic geology and petrology in theory as well as in the field.
More specifically, for every tonne of steel recycled, you can save 1.5 tonnes of iron ore, reduce emissions by 86% and reduce water pollution by 76%. This means that, by scrapping end-of-life vehicles , you are contributing to less air pollution, less water pollution and less mining waste, which means increased sustainability.
A fundamentally distinct, sulfide-poor variant of intense acid (advanced argillic) alteration occurs at the highest structural levels in iron oxide-rich hydrothermal systems. Understanding the mineralogy, and geochemical conditions of formation in these sulfide-poor
Therefore, chapters dealing with the environmental and economic sustainability aspects are appreciated. Although iron ores have been explored and studied for millennia, in permanent processes of research and innovation, new, often interdisciplinary, topics arise.

According to the observed differences in ore mineralogy (especially, iron-bearing ore minerals) and fluid inclusions of quartz from the mesothermal-type deposits in both areas, we suggest that pyrrhotite-rich, mesothermal-type deposits in the Youngdong area
22/4/2019· Iron ore miners have suffered for a while. Cheap imports and global steelmaking overcapacity have dragged down prices for domestically manufactured steel, thereby reducing demand for iron ore. However, the industry is expected to see robust growth through 2023
