Revised mining designs on comprehensive utilization of Boron iron

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.WT
