鲁中某铁矿加工与砂石制备混用工艺实践

Mixed Process Practice of Processing and Sand Preparation of an Iron Ore in Central Shandong Province

鲁中某铁矿企业为难选铁矿石矿山,叠加早年市场环境因素,项目预测难以盈利,为此搁置多年未建设。为了实现高效集约地开发该矿产资源,针对该类型磁铁矿为主的原矿特点和现有砂石市场的产品粒度需求,将铁矿加工和砂石制备工艺进行了深度融合,形成了一套工艺兼具2种市场产品的混合加工工艺,解决了传统工艺设备多、厂房多、占地大、操作人员多的问题,在降低投资及成本的同时,为企业额外带来了巨大的经济效益,并进一步促进了节能减排工作,符合国家“双碳”政策。

An iron ore enterprise in central Shandong is a refractory iron ore mine.Superimposing the early market environment factors,the project forecast is difficult to be profitable,and it has not been built for many years.In order to achieve efficient and intensive development of this mineral resource,according to the characteristics of this type of magnetite-based raw ore and the product particle size requirements of the existing sand and gravel market,the iron ore processing and sand and gravel preparation processes are deeply integrated to form a set of processes with two market products.The mixed processing process solves the problems of many equipment,many factories,large land occupation,and many operators in traditional process.While reducing investment and cost,it brings huge economic benefits to the enterprise,and further promotes energy conservation and emission reduction work,which is in line with the national"double carbon"policy.
