Production strategy associated with quality requirements in iron ore open pit mines under price sensitivity

铁矿石是加拿大的重要资源。加拿大的铁矿石产量为4280万吨，其中 2013年的价值为53.34亿美元。全球铁矿石价格从2011年的每吨187美元降至每吨68美元 2015年初。这危及铁矿石生产商未来的运营。当前业务的可持续性 开发项目可以通过(一)更高效地开采铁矿石和(二)减少项目来管理。 成本。在这个范围内，新千年钢铁公司决定与库姆拉尔教授的团队合作， 进行一项旨在推进调度的研究，以便(1)考虑铁矿石的质量特征， (2)采用内部倾卸方案；(3)采用半移动式破碎机。因此，操作 效率可以提高，相关成本可以降低。铁矿石的质量取决于 许多变量，如铁、氧化铝、二氧化硅、石灰和磷。因此，这项研究将开始一个 质量参数的多变量分析。然后，调度将被表示为网络的最大化 在满足质量要求的约束下的项目现值。一种新的废物处理方式 管理系统也在规划中。在这方面，内部倾销选项将纳入 调度以减少材料搬运、运输和矿山关闭的成本。目标是限制这些区块 含有对环境有害的元素进入以前的生产区。因此，可能的环境 问题是可以避免的。此外，将半移动式破碎机融入生产系统将是 为进一步降低装载和运输成本进行了调查。这需要了解爆破之间的相互作用 性能和压倒性。新千年钢铁公司已经成长为一家新兴的生产商，控制着它 世界上最大的铁矿石资源之一。铁矿石市场的最新发展使该公司 实现最先进的生产方法。麦吉尔的研究人员将通过发起 新的生产计划。该Engage项目还将帮助新千年钢铁公司建立 与申请人的研究团队进行长期的研究合作。

Iron ore is an important resource for Canada. Iron ore production of Canada was 42.8 Million tonnes with a value of $5.334 Billion in 2013. Global iron ore prices declined from $187 per tonne in 2011 to $68 per tonne in early 2015. This jeopardizes future operations of iron ore producers. The sustainability of present operations and development projects can be managed by (i) extracting iron ore more efficiently and (b) reducing project costs. In this scope, New Millennium Iron Corp. has decided to collaborate with Prof Kumral's team to carry out a research aiming to advance in scheduling such that (1) quality characteristics of iron ore are considered, (2) internal dumping option is incorporated and (3) semi-mobile crusher is performed. Thus, operation efficiency can be increased and the associated costs can be decreased. The quality of iron ore depends upon many variables such as iron, alumina, silica, lime and phosphorus. Therefore, the research will start a multivariate analysis of quality parameters. The scheduling will be then formulated as maximization of net present value of a project under the constraints of meeting quality requirement. A new waste disposal management system is also planned. In this context, internal dumping option will be incorporated into the scheduling to reduce material handling, transportation and mine closure costs. The goal is to confine the blocks containing environmentally harmful elements into former production areas. Thus, possible environmental problems can be avoided. Furthermore, embodying a semi-mobile crusher into production system will be investigated to further reduce loading and hauling costs. This needs to understand interaction between blasting performance and crushing. New Millennium Iron Corp. has grown into an emerging producer controlling one of the largest iron ore resources in the world. Recent developments in the iron ore market make the company fulfill the cutting-edge production approaches. McGill researchers will assist this objective through initiating new production schedules. This ENGAGE project will also help New Millennium Iron Corp. in establishing long-term research collaboration with the applicant's research team.
