摘要

An accurate knowledge of the chemical, mineralogical and physical characteristics of ores andrnmineral products that are mined, processed and traded is crucial to effective resource utilisation, plantrndesign, process optimisation and finally quality control to ensure that contract specifications are met.rnHowever, all too often the responsibility for sampling is entrusted to managers and personnel who dornnot fully appreciate the significance and importance of collecting representative samples for analysis,rnand everyone seems satisfied as long as some material is collected and returned to the laboratory forrnanalysis. Furthermore, sample stations incorporated into the design of new plants are often the firstrncasualties when cost cutting exercises commence. This needs to change, because there is little point inrnaccurately analysing samples if they are not representative in the first place. The resultant analysesrncan be next to meaningless and the effort taken to analyse such samples is to a large extent a waste ofrntime and resources.rnUltimately, a poor knowledge of the characteristics of ores and mineral products limits the ability ofrnmining companies to optimise the life of ore resources and plant performance, and failure to meetrnfinal product specifications can have disastrous consequences, including price penalties and morernseriously loss of sales contracts. It is high time that sampling is given the attention it deserves as thernfirst critical step in the quality measurement chain.
