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）。在工业卷积期间，铁的重要性大大提高。目前，多达98％的采矿铁被用作钢铁行业的主要投入，因为钢铁是许多行业所要求的，例如：建筑和重型产业，造船，机械和机动车制造，铁路建设，桥梁建设，桥梁建造，桥梁建造和工程应用。然后，矿石从矿物工程中生产了一系列矿物质的钢铁，包括矿物质的矿物质，包括矿物质供应（包括矿物质供应），并遵循钢铁厂的生产，构成了钢铁，并构成了钢铁的生产（构成了钢铁，均采用了钢铁材料，又是对矿物质的造型。还原过程最常见的是爆炸炉，这具有一些重要的环境缺陷。欧洲联盟国家的一份报告称，目前没有技术在技术上可行且经济合理的替代方案可以彻底替代铁矿石生产钢的焦化煤。然而，最近，低温碱性电解的进步引入了环保的替代方案。对于所有铁矿石浓缩物而言，本技术不能达到相同水平的效率；因此，该项目将对矿物学对低温碱性电解过程的影响进行评估，并将加拿大铁矿矿床的目的旨在挑战。
