Industry:Mining
Concentrated ground water flow at the water table in a formation or structure of high permeability.
Industry:Mining
Concentrating heavy minerals by washing unconsolidated material through a box (sluice) equipped with riffles that trap the heavier minerals on the floor of the box.

Concentrations of mineral formed by the grinding action of natural forces (wind, wave, or frost) and the selective transporting action of tides and winds.
Industry:Mining
Concrete in which large blocks of stone, roughly squared, are placed and arranged roughly in courses, so that they break joint both horizontally and vertically. The stones are placed with not less than 6 in (15 cm) of space between them so that the concrete may be properly rammed. Care is taken that all voids are filled with concrete.
Industry:Mining
Concrete poured into a framework that is fitted with a linen filter in the form of a vacuum mat. As a result of the process ensuing, the concrete attains its 28-day strength in 10 days and has a 25% higher crushing strength.
Industry:Mining
Concrete that is mixed at a central mixing plant and delivered to a site in special equipment designed to prevent its segregation.
