矿■矿强度不仅取决于工艺设备的能力,而且还取决于矿山生产工艺制度与采矿方法完善程度。为了保证矿山企业和车间的正常生产,必须由矿山以及选矿厂为后面各加工阶段提供品位相同的原矿和中间产品。以塔什塔戈尔铁矿为例,按照规定标准,必须为选矿厂提供平均品位(磁铁矿Fe_3O_4含量,下同)不低于37.3％、块度不大于300毫米的原矿。一昼夜当中 Mine ■ mine strength depends not only on the ability of process equipment, but also depends on the mine production process system and mining methods to improve the degree. In order to ensure the normal production of mining enterprises and workshops, the ore and intermediate products of the same grade must be provided by the mines and the concentrator for the subsequent processing stages. Take Tashtagol Iron Ore as an example, in accordance with the stipulated standards, the average grade (magnetite Fe_3O_4 content) of not less than 37.3% must be provided to the beneficiation plant and the ore block with a grain size of not more than 300 mm shall be provided.
