With the comprehensive recovery and utilisation of resource mining, the multi-source and multi-target ore blending method has become one of the focuses of the mining industry. Scientific and reasonable ore blending can effectively reduce the transportation cost of the enterprise. It can also ensure that the ore grade, washability index and iron carbonate content meet the requirements of the concentrator and significantly improve the comprehensive utilisation rate and economic benefits of the ore. An ore blending method for open-pit iron ore is proposed in this paper. The blending method is realised by establishing the ore blending model. This model aims to achieve maximum ore output and the shortest transportation distance, ore washability index, total iron grade, ferrous iron grade and iron carbonate content after the ore blending meets the requirements. This method can meet the situation of a single mine to a single concentrator and that of a single mine to multiple concentrators. According to the results of ore blending, we can know the bottleneck of current production. Through targeted optimisation management, we can tap the production potential of an open-pit mine.}, type={Article}, title={Multi-Source and Multi-Target Iron Ore Blending Method in Open Pit Mine}, URL={http://journals.pan.pl/Content/125532/PDF-MASTER/Archiwum-67-4-03-Jiang%20Jao.pdf}, doi={10.24425/ams.2022.143678}, keywords={Iron Ore blending, Multi-source and Multi-target, open pit mine}, }
