放出椭球体图象的现场测定是把放矿工作的科研与生产实践结合起来的重要环节。进行这种结合的目的,是降低放矿过程中的矿石损失和贫化。在这篇文章中,提出了初步圈定放出椭球图象和对这些图象进行检验的方法,说明了绘制放出椭球体的参数和体积的关系曲线的必要性,导出了放出椭球体体积计算公式,并论证了各放出椭球体顶点的连线(即通常所说的流轴)近似于抛物线。 The on-site measurement of releasing ellipsoid images is an important link that combines the scientific research and production practice of ore-dressing. The purpose of this combination is to reduce ore loss and depletion in the process of ore drawing. In this paper, we propose a method of initial delineation of ellipsoid images and their verification. The necessity of plotting the relationship between the parameters and volume of the emission ellipsoid is illustrated. The formula for calculating the volume of the released ellipsoid is derived It is also demonstrated that the connection of the apexes of each emitting ellipsoid (that is, the so-called stream axis) is similar to a parabola.
