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.

铁一直是人类历史的重要组成部分，例如铁器时代是三年级系统的第三个时代（石头和青铜是其他两个时代）。在工业期间 革命，铁的重要性急剧增加。目前，多达98％的采矿铁被用作 钢铁工业中制造钢铁的主要投入，因为许多行业都需要钢铁，例如：建筑 以及重工业，造船，机械和汽车制造，铁路建设，桥梁 建筑和工程应用。 铁从其矿石产生的是一系列矿物加工步骤，包括矿物学 分析，然后还原为铁（然后是钢生产）。减少过程最常见 利用爆炸炉，有一些重要的环境缺陷。欧盟的报告 目前没有技术在技术上可行且经济合理的替代方案 在用铁矿石生产钢中，完全取代了焦化煤。但是最近，进步 低温碱性电解引入了环保的替代方案。这 对于所有铁矿石浓缩物而言，技术并不能达到相同水平的效率；因此，这个项目将 研究矿物学对低温碱性电解过程的影响，并针对 对加拿大铁矿床的优化。
