本報告的目的,主要為簡述有色金屬鑛山試料的採取及加工之原則與方法。在勘查和探鑛工作階段當中,採取试料的任務,不外乎是以质量来說明鑛體自然露出部分,或在探鑛坑道内鑛體露出部分的特徵。當评定鑛床價值时,採取某一種有用鑛物试料的結果,可作為充分的根據;但同時对另一种有用鑛物採集試料的結果(如氧化或流失的硫化鑛),则僅可提供為参考。四氧化的外部或流
The purpose of this report is to briefly outline the principles and methods for taking and processing non-ferrous metal mining samples. Among the exploration and prospecting phases, the task of taking samples is nothing less than to show the natural exposed part of the ore body or the exposed part of the ore body in the prospecting tunnel. When assessing the value of a deposit, the results of a sample of a useful mineral may be used as a sufficient basis; but at the same time as a result of the collection of another useful mineral (for example, oxidized or depleted sulphide ores) reference.
