Mining in the engineering discipline is the extraction of minerals from underneath, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying.A mining engineer may manage any phase of mining operations, from exploration

Percent moisture on a dry basis is the mass ratio of moisture to moisture-free solid expressed as percentage. Thus, when the moisture content of the solid is 25% on a dry basis, there are 25 parts by weight of water associated with 100 parts by weight of dry solid. Or, 125 parts by weight of the wet solid contains 25 parts by weight of water.

The method is used to produce a wide range of shapes, from rounds, squares, “L” shapes, “T” shapes and tube, though to complex sections that can be difficult to make by any other method. The latter are often specific to a particular application, and a stock of ready-made dies will be held by an extrusion works ready for when these,

Hematite - An oxide of iron, and one of that metal's most common ore minerals. High grade - Rich ore. As a verb, it refers to selective mining of the best ore in a deposit. High-grader - One who steals rich ore, especially gold, from a mine. Hoist - The machine used for raising and lowering the cage or other conveyance in a shaft.

Wet storage is usually suitable for shorter down-time periods or if the unit may be required to go on-line quickly. Large boilers with complex circuits are difficult to dry, so they should be stored by one of the wet storage methods. Dry Storage. For dry storage, the boiler is drained, cleaned, and dried completely.
