The fine earth fraction includes any particle less than mm (.078 inches) and is divided into three classes of size: sand, silt, or clay. To put this into perspective, the width of the lead in a No. 2 pencil is approximately mm. Table 1 provides descriptions of each class in the fine earth fraction.

communities. Clay has also been identified as a needed resource, for the purpose of geotechnical applications such as liners for stockpiles. This report summarizes the project's field observations, geologic relationships, and mapping results related to sand and gravel distribution and quality.

Processing Your Clay. Sieving can be done either of two ways. The clay can be pulverized when dry and then sieved, or dried, slaked down in water, then sieved. The finer the mesh used, the fewer inclusions your working clay will have. I suggest using a 50mesh screen, although a 30 or 80mesh will do.

Mining and Mitigation Program Quick Links. Borrow pits are regulated by the Water Management Districts . Resources mined in Florida include phosphate, limestone, dolomite, shell, heavy minerals, fuller's earth, peat, clay, gravel and sand.

Sand and Gravel Mining Industry. The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind. In the Platte River valley, these deposits can be greater than 150 feet deep and often contain mammoth bones and teeth, bison bones and petrified wood.

Oil sands (or tar sands or bituminous sands ) refer to a mixture of sand, water, clay, and bitumen (which we have seen refers to the heaviest of hydrocarbon mixtures found in crude petroleum). The mixture is usually between 1% and 20% bitumen. The bitumen is a viscous semisolid.

Coarse sand and phosphate particles swirl to the bottom of the cyclone and exit. The fine clays are collected and pumped to large impoundment ponds which are discussed in another section (the "clay pond primer"). The + mm sand and phosphate move on to the next process operation.

WATER USE IN INDUSTRIES OF THE FUTURE (REVIEW DRAFT) in a variety of industries, including paper manufacture, ceramics, and paint formula­ tions. Papermaking uses a large amount of kaolin clay, and crude kaolin is not useful as a mined product until it is processed to remove impurities. In Georgia, kaolin deposits are normally lo­

Mining engineering: the practice of applying engineering principles to the development,planning,operation,closure,and reclamation of mines Some terms distinguish various types of mined minerals.

Oil sands, also known as "tar sands," are sediments or sedimentary rocks composed of sand, clay minerals, water, and bitumen. The oil is in the form of bitumen, a very heavy liquid or sticky black solid with a low melting temperature. Bitumen typically makes up about 5 to 15% of the deposit.
