In a discussion of sampling it is useful to distinguish two forms of solids , monolithic and particulate, as well as liquids and gases and to treat each material type as a separate category. At the same time, it is important to recognize that mixed phases also frequently need to be sampled; gases dissolved in liquids and solids, particles suspended in liquids, and solid and liquid aerosols are some examples. Sometimes the object of study is in one phase form, but the sample must be in another.

Developments in Geomathematics 4: Sampling of Particulate Materials: Theory and Practice reviews the theory and practice of sampling particulate solids, such as ores and concentrates. With examples borrowed from the mining, metallurgical, and cement industries, the book examines particulate materials of vegetable and mineral origin, including cereals, oil seeds, sugar beets, granulated drosses or slags, bars, plates, and ingots. Organized into nine parts encompassing 34 chapters, this volume begins with an overview of the theory of sampling and sampling-error generating mechanisms. It then discusses the continuous selection and discrete models of the increment sampling process and the materialization of punctual increments.

Particle Size Measurements pp Cite as. Particulate materials are often produced in very large quantities. In contrast, usually small quantities are used for characterization or applications. There are two reasons that small samples often give poor representation of the average quality of the bulk. One reason is the discrete nature of particles. This necessitates a minimum amount of sample to reach a desired variance for a stated PSD parameter. The second reason is the fact that both process fluctuations and segregation during transport and storage may lead to large differences in quality at different locations in a product lot.

The technology was principally developed to count blood cells quickly by measuring the changes in electrical conductance as cells suspended in a conductive fluid passed through a small orifice. In the past seventy-five years, the technology has also been used to characterize thousands of different industrial particulate materials. Drugs, pigments, fillers, toners, foods, abrasives, explosives, clay, minerals, construction materials, coating materials, metals, filter materials, and many other sample types have all been analyzed using the Coulter Principle.

Ore and waste must be defined effectively to ensure an economically optimized mill feed in all mining operations. Grade control is essential for efficient mine operation, with key performance indicators including: effective definition of ore and waste and marginal ore if required ; correct delivery of ore and waste to their designated destination; optimized feed grade to the mill; minimal dilution; and maximum recovery.

Gy's sampling theory is a theory about the sampling of materials, developed by Pierre Gy from the s to beginning s [1] in articles and books including:. The abbreviation "TOS" is also used to denote Gy's sampling theory. Gy's sampling theory uses a model in which the sample taking is represented by independent Bernoulli trials for every particle in the parent population from which the sample is drawn. The two possible outcomes of each Bernoulli trial are: 1 the particle is selected and 2 the particle is not selected.
