Finding a new sampling method and studying its characteristics with respect to existing sampling methods

Abstract

In mineral processing industry, quality of minerals has to be measured in several stages of processing. In measuring the quality, obtaining accurate samples is of prime importance in representing the bulk material. There are number of sampling methods which are industrially used for mineral sampling. But each of these methods has their own weaknesses that make some of them inappropriate in using as the most suitable sampling method. Most of them are human biased. Some sampling methods have simple protocol, but their sample accuracy is low. More accurate methods require advanced instruments and involve high cost and more time. Any sampling method to be successfully used should not only be of highly accuracy, but should be simpler, more cost effective, less time consuming and easier to be applied in the field as well. If any sampling method with the above characteristics could be introduced, it will be a good substitute for many existing methods. Through literature studies combined with innovative ideas, it was possible to introduce a new sampling method. This sampling method developed has the characteristics of being simple and quick in operation, minimal effects due to segregation, high accuracy, lesser equipment usage, cost effectiveness and less bias to operator experience.
