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.
