硼铁矿综合利用采矿设计优化思路

     

摘要

为提升硼铁矿综合利用水平,提高企业盈利能力,通过研究首钢硼铁矿矿床概况、前期地质工作、矿石性质,结合中冶北方编制的辽宁首钢硼铁矿采矿设计,提出进一步优化设计方案思路.坚持“以硼为主,综合利用”方针,根据硼品位及赋存方式不同,分批开采,降低采出矿石硼贫化率;通过排土方案经济性比较,提出增加排土台阶,降低排土费用,改善矿车运行环境;研究采场外排水替代新水,详细测算成本费用,有利于节约水资源,降低取水成本;强化后期生产组织,及时回收挂帮矿;提前组织周家大院矿体开采,满足当前选矿需要.%By studying the profiles of Shougang Boron iron deposits, early geological explorations. Ore qualities, and the mine design of Liaoning Shougang Boron iron compiled by metallurgy of north China, a concrete optimization design idea is put forward to upgrade the comprehensive utilization level of Boron iron and profitability. According to comprehensive utilization based on boron guideline and different grades and occurrence modes of boron, exploitations should be done in batches to reduce the dilution rate of boron ore. It is proposed that more dumping steps should be added to lower the costs of dumping and improve the operating environment of tub after comparing the costs of different dumping programs. Also research on replacing fresh water with drain water should be done to save water resources and reduce the water costs. Besides , it is recommended that management in the later stage should be enforced to recovery the hanging wall ore timely, and ore exploitation of Zhou Courtyard should be organized in advance to meet the current needs of mineral process.
