矿石工业试验成果是选矿设计的重要依据,其可信程度及其使用价值同采样的代表性是有很大关系的。工业试验采样工作的实践表明,无论从采样数量看还是从采样施工条件及技术要求看,工业试验的采样难度比小型试验的采样难度大得多,因而所需要的人力、物力及费用都是很可观的。这就要求参加采样设计和施工的人员,必须严肃、认真地对待此项工
The result of the ore industry test is an important basis for the beneficiation design, and its credibility and its value are closely related to the representativeness of the sample. Industrial trial sampling practice shows that, in terms of the number of samples or from the sampling of construction conditions and technical requirements, industrial sampling is more difficult than the sampling of the small test is much more difficult, and therefore the required manpower, material resources and costs are very Considerable. This requires that those who take part in sampling design and construction must take this job seriously and seriously
