我国铁矿资源储量总体上都是贫矿，资源利用水平低。鞍钢集团矿业公司（鞍钢矿业）在工程哲学指导下，在现有技术集成和创新的基础上，创建了“五品联动”工程管理模式。将包含地质工程、采矿工程、配矿工程、选矿工程、冶炼工程在内的矿冶工程看作一个整体，统筹考虑地质品位、采矿品位、入选品位、精矿品位和入炉品位5 种品位，以矿冶工程的总成本为目标，集成优化。“五品联动”模式的提出和应用，解决了贫铁矿利用难题，为实施“自给为主”的资源战略提供了支撑。

All of Chinese iron ore reserves are lean ores and the resource utilization is very low. Led by the idea of engineering philosophy and based on technological integration and creation,Ansteel Group established the "five grades ganged" engineering management mode. It views mining and metallurgical engineering, including the geologic,mining,ore blending,concentration and smelting engineering,as a whole and considers the geological,mining,feed,concentrate and charging grades together with objective of the integrated optimization of the overall costs. With the establishment and application of the "five grades ganged" mode,Ansteel Group has solved the lean iron ores exploitation problem and supported the"self-sufficiency-based" resource strategy.
