ABSTRACT
The Fundamental Sampling Error FSE is the only error that is never zero because it is generated by the intrinsic heterogeneity of a particulate solid; furthermore, through comminution processes, the smaller the largest fragment size becomes, the larger the liberation factor. Fortunately, the factor d 3 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781351105934/7fcc19d8-d59f-45bd-9ddf-91c689ba414e/content/inline11_1.tif"/> is likely to decrease much faster than ℓ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781351105934/7fcc19d8-d59f-45bd-9ddf-91c689ba414e/content/inline11_2.tif"/> increases. Therefore, changing d through comminution can provide a means to minimize the variance of the Fundamental Sampling Error. In this chapter we review all the practical applications of formula 10.46, used to produce sampling protocols in accordance with a carefully determined objective, and to evaluate the precision of a protocol used by others.
