Effect of mineralogy on the low temperature electrolysis of iron ore

铁历来都是人类历史的重要组成部分，铁器时代是三代制的第三个时代(石器和青铜是另外两个时代)。在工业时代 革命后，铁的重要性急剧增加。目前，高达98%的开采铁被用于 钢铁工业中炼钢的主要投入，因为钢铁是许多行业的必需品，如：建筑 以及重工业、造船、机械和机动车辆制造、铁路建设、桥梁 建筑和工程应用。 从其矿石中生产铁是通过一系列的选矿步骤，包括矿物学 分析，然后还原成铁(然后是钢生产)。最常见的减量过程 使用的是高炉，这对环境有很大的不利影响。欧盟的一份报告 国家指出，目前没有技术上可行和经济上合理的替代品 在铁矿石炼钢中完全取代炼焦煤。然而，最近，这种进步 低温碱法电解法推出了一种环境友好的替代方案。这 技术对所有铁矿石精矿的效率并不是一样的；因此，这个项目将 研究了矿物学对低温碱性电解过程的影响，旨在 加拿大铁矿资源的优化。

Iron has been a vital component of mankind's history throughout the ages, exemplified with the Iron Age being the third epoch of the three-age system (stone and bronze being the other two). During the Industrial Revolution, the importance of iron increased dramatically. Currently, up to 98% of the mined iron is used as the primary input in steel industry to make steel, as steel is required by many industries such as: construction and heavy industries, shipbuilding, machinery and motor vehicle manufacturing, railway construction, bridge building and engineering applications. The production of iron from its ores is through a series of mineral processing steps, including mineralogical analyses, followed by reduction to iron (and then steel production). The reduction process most commonly utilises a blast furnace, which has some significant environmental drawbacks. A report by the European Union states that currently there are no technologically feasible and economically reasonable alternatives to completely replace coking coal in the production of steel from iron ore. Recently, however, the advancement of low temperature alkaline electrolysis has introduced an environmentally-friendly alternative. This technology does not work to the same levels of efficiency for all iron ore concentrates; as such, this project will investigate the impact of mineralogy on the low-temperature alkaline electrolysis process, and aims at optimisation for Canadian iron deposits.
