阿赫达尔斯克多金属矿床矿石的特征是硫化矿物呈非均匀嵌布。金属矿物的单体粒度范围很宽——从数微米到数毫米。为了获得较高的选别指标,矿石必须磨细到75—85%-0.074毫米。在一段磨矿中要达到达样的磨细度,必将大大地降低球磨机的生产率,同时会导致粗粒矿物的过磨细,从而造成金属的损失。如磨矿粒度过粗而不足以使细粒矿物单体解离时,也会导致这些金属的损失。
The Ahuddalsk polymetallic ore is characterized by a heterogeneous distribution of sulfide minerals. Metallic minerals have a wide range of monomer particle sizes - from a few microns to a few millimeters. In order to obtain a higher sorting index, the ore must be ground to 75-85% -0.074 mm. In a period of grinding to achieve sample-like degree of grinding, will greatly reduce the productivity of ball mill, at the same time can lead to coarse grinding of fine minerals, resulting in the loss of metal. Such as grinding particle size is too coarse and not enough to make fine-grained mineral monomer dissociation, can also lead to the loss of these metals.
