cobbles, gravel, sand, silt, and clay. numerous grade scales have been developed to establish the limits of size for each of these classifications. table 3–1 shows some of the commonly used grade scales for compari-son. note that the range in size for a particular class of particle may differ from one classification system to another..soil properties and the unified soil classification system,basic soil types are: gravel, sand, silt, or clay. because soil can contain all of these components, the classification system is used to describe the major components; for example, clayey sand with gravel, sandy silt, or silty clay with sand. the percentages and behavior of each component can be determined from laboratory tests or they can be.classification of aggregates: grain size, density, shape,that is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. fine aggregates include things such as sand, silt and clay. crushed stone and crushed gravel might also fall under this category. typically, fine aggregates are used to improve workability of a concrete mix. coarse aggregates measure above the 4.75mm limit. these are more likely to be natural.amazon.com: soil sifter,more buying choices $13.37 (3 used & new offers) hemoton 8pcs sifting pan outdoor gold panning soil sifter sieve fine mesh screen classifier for garden outdoor $11.39 $ 11 . 39
gold with a specific gravity of 15 to 19.3 and black sand at 5 to 6+, when classified to the same mesh size, will allow the gold contained to be easily recovered. proper classification (sorting by size) is the key to fine gold recovery form black sands. without classification, gravel three times the size of gold will be recovered with the gold, hence the necessity for proper classification..goldpans - placer gold design,the only pan that puts the gold dead center bottom. no searching through heavy black sand concentrates when a simple panning method is applied. made from steel not plastic. weight not an issue as pan is used under the water surface. classifier excellent for washing heavy rocks and sticky clays. it keeps material in pan fluid so gold drops quickly..unified soil classification system (uscs),b) sands (s): in these soils, more than 50% of the coarse fraction is smaller than 4.75mm is sieve size. this sub-division includes sands and sandy soils. each of the above sub-divisions are further divided into four groups depending upon grading and inclusion of other materials. w.soil mechanics: description and classification,• classification is the laboratory-based process of grouping soils with similar engineering characteristics into categories. for example, the unified soil classification system, uscs, (astm d 2487), which is the most commonly used system in geotechnical work, is based on grain size, gradation, and plasticity. the aashto system (m 145), which is
