黑色冶金矿石的工业指标,系指供选矿厂用的各种贫铁原矿石、入炉的高炉富矿石、平炉矿石、锰矿石,供耐火厂制各种耐火制品的矿石质量指标。矿石工业指标订得过高,虽可改善选矿、冶炼与耐火材料的技术经济指标,但有大量的资源不能得到充分利用;订得偏低,虽可充分利用矿石资源,但选矿、冶炼、耐火材料的技术经济指标就要降低。因此,如何合理确定矿石工业指标是一个非常重要的问题。制订合理的矿石工业指标,应根据选矿、冶炼技术水平、资源利用情况和开采加工技术条件等来全面考虑。下面就分别谈谈自已对几种黑色冶金矿石工业指标的意见。(一)铁矿石
The industrial index of black metallurgical ore refers to the quality indexes of various refractory raw ore for ore dressing plant, rich ore of blast furnace into furnace, open hearth ore and manganese ore, and various refractory products for refractory plant. Ore industry indicators set too high, although can improve the beneficiation, smelting and refractory technical and economic indicators, but a large number of resources can not be fully utilized; set low, although can make full use of ore resources, but beneficiation, smelting, refractory Technical and economic indicators of the material will be reduced. Therefore, how to reasonably determine the ore industry is a very important issue. The development of a reasonable ore industry indicators should be based on mineral processing, smelting technology, resource utilization and mining technology conditions to fully consider. Here to talk about their own on several black metallurgical ore industrial indicators of opinion. (A) iron ore
