Effect of mineralogy on the low temperature electrolysis of iron ore

铁一直是人类历史的重要组成部分，以铁器时代为例，这是三个时代系统中的第三个时代（石头和青铜是另外两个）。在工业革命期间，铁的重要性急剧增加。目前，高达98%的铁矿石被用作钢铁工业的主要投入，因为许多行业都需要钢铁，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的矿物加工步骤，包括矿物学分析，然后还原成铁（然后生产钢）。还原过程最常用的是鼓风炉，这有一些明显的环境缺陷。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品可以完全取代炼焦煤，用于从铁矿石生产钢铁。然而，近年来，低温碱性电解技术的发展带来了一种对环境友好的替代方法。该技术并不能对所有的铁精矿达到相同的效率水平;因此，该项目将研究矿物学对低温碱性电解过程的影响，并旨在优化加拿大铁矿床。

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.
