铁精矿矿浆品位原位EDXRF(能量色散X射线荧光)分析试验在攀钢选矿厂进行,矿浆中水与矿粉体积比在2/5~2/1之间,在(L×W×H=8×2×20cm)的沉淀条件下,经过9 min自然沉淀,静态测量(60 s);从测量结果看出:仪器分析周期约10 min,与化学分析结果的绝对误差小于0.3%,并说明铁精矿矿浆品位在线分析完全可行,这为开发新型在线铁精矿矿浆品位的EDXRF分析仪器提供了依据。
The in-situ EDXRF (Energy Dispersive X-Ray Fluorescence) analysis of the ore grade of iron concentrate was carried out in the Panzhihua Iron and Steel Concentrate. The volume ratio of water to ore in the slurry was between 2/5 and 2/1, = 8 × 2 × 20cm) precipitation, static precipitation after 9 min (60 s); from the measurement results: the instrument analysis cycle of about 10 min, and the absolute difference between chemical analysis results less than 0.3%, and This shows that the online analysis of ore concentrate grade is feasible and feasible, which provides a basis for the development of new EDXRF analysis equipment for the new online ore concentrate grade.
