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.

铁器在各个时代都是人类历史的重要组成部分，铁器时代是三时代体系的第三个时代（石器时代和青铜器时代是另外两个时代）就是一个例子。工业化期间 革命后，铁的重要性急剧增加。目前，高达 98% 的开采铁被用作 钢铁工业的主要投入是制造钢材，因为许多行业都需要钢材，例如：建筑业 和重工业、造船、机械和机动车辆制造、铁路建设、桥梁 建筑和工程应用。 从矿石中生产铁是通过一系列矿物加工步骤，包括矿物学 分析，然后还原为铁（然后生产钢）。最常见的还原过程 使用高炉，这有一些显着的环境缺陷。欧盟的一份报告 指出目前没有技术上可行且经济上合理的替代方案 完全替代铁矿石炼钢中的焦煤。不过最近进展 低温碱性电解引入了一种环保的替代方案。这 技术并非对所有铁精矿都具有相同的效率水平；因此，该项目将 研究矿物学对低温碱性电解过程的影响，旨在 加拿大铁矿床的优化。
