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 IndustrialRevolution, the importance of iron increased dramatically. Currently, up to 98% of the mined iron is used asthe primary input in steel industry to make steel, as steel is required by many industries such as: constructionand heavy industries, shipbuilding, machinery and motor vehicle manufacturing, railway construction, bridgebuilding and engineering applications.The production of iron from its ores is through a series of mineral processing steps, including mineralogicalanalyses, followed by reduction to iron (and then steel production). The reduction process most commonlyutilises a blast furnace, which has some significant environmental drawbacks. A report by the European Unionstates that currently there are no technologically feasible and economically reasonable alternatives tocompletely replace coking coal in the production of steel from iron ore. Recently, however, the advancementof low temperature alkaline electrolysis has introduced an environmentally-friendly alternative. Thistechnology does not work to the same levels of efficiency for all iron ore concentrates; as such, this project willinvestigate the impact of mineralogy on the low-temperature alkaline electrolysis process, and aims atoptimisation 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。在工业革命期间，铁的重要性急剧增加。目前，高达 98% 的矿铁被用作钢铁工业的主要原料来制造钢材，因为许多行业都需要钢材，例如：建筑和重工业、造船、机械和机动车辆制造、铁路建设、桥梁建设和工程应用。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）。还原过程最常用的是高炉，但它对环境有一些显着的缺点。欧盟的一份报告指出，目前还没有技术上可行且经济上合理的替代方案可以完全替代铁矿石炼钢中的炼焦煤。然而，最近低温碱性电解的进步引入了一种环保的替代方案。该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，旨在优化加拿大铁矿床。
