近年来,选矿新设备、新工艺不断出现,在新厂建设前,为提供设计需要的技术数据,常作半工业、工业性选矿试验。如何采取该种大量矿样,本文试作粗浅探讨,以供参考。一、制订的原则和方法 1.根据实验目的确定试样个数。如某工业实验目的:①采用大块度干式磁选,排出炼钢矿石中的废石;②对混合矿石(除炼钢矿石外的各种贫矿和富矿)验证流程试验的可靠性。因此样品个数为2。
In recent years, new equipment, new processes continue to appear in the new plant before the construction, in order to provide the technical data needed for design, often for semi-industrial, industrial beneficiation test. How to take such a large number of ore samples, this paper try to discuss shallow, for reference. First, the development of principles and methods 1. According to the experimental purpose to determine the number of samples. Such as the purpose of an industrial experiment: ① using large-scale dry magnetic separation, discharge of waste rock in steel ores; ② mixed ore (except for steel ores and other lean ore and rich ore) to verify the reliability of the process test. So the number of samples is two.
