辐射分选机的标准源曲线广泛应用于选矿实践,利用这些曲线对分离过程的选择性、选机灵敏度的漂移和涨落等进行定量评价,可以提高其信息价值。标准源曲线(图1)描述不同品位标准源(C)选为精矿或尾矿的概率(P精或P尾)与选机所确定的、用品位表示的调整值(μ)之间的关系。实质上,标准源曲线与重选常用的特龙普曲线(分配曲线)是相同的。
The standard source curve of the radiation sorter is widely used in the beneficiation practice. Using these curves to quantitatively evaluate the selectivity of the separation process, the drift and fluctuation of the machine sensitivity, etc., can improve the information value. The standard source curve (Figure 1) describes the difference between the probability (P or P tail) that a different grade standard source (C) is selected as concentrate or tailings, and the adjustment value (μ) relationship. In essence, the standard source curves are the same as those used for resequencing (distribution curves).
