Surface mining methods can be broadly classified as openpit mining, which includes quarrying, strip mining, contour mining, dredging, and hydraulic mining. Topography and the physical characteristics of the deposit strongly influence the choice of method. In openpit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. This method

of water (a process called ''hydraulic mining'') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is an environmentallydestructive type of mining, releasing large quantities of sediment that can impact surface water for several miles downstream of the placer mine.

Mining in its broadest sense is the process of obtaining useful minerals from the earth''s crust. A mineral is generally defined as any natural accruing substance of definite chemical composition and consistent physical properties. An ore is a mineral or combination of minerals from which a useful substance, such gold, can be extracted and marketed at a price that will recover the costs of

mining and processing of metalliferous and nonmetallic ores. Many terms have a wide variety of accepted meanings, or their meanings have changed over time. Other terms which used to be widely used ( those associated with sluicemining) are seldom used today. The use of some terms is limited to restricted mining localities (often arising from Comish or other ethnic mining slang), or they

fact, reclamation processes typically begin while active mining is still occurring in another area of a mine. Thus, mining and restoration can be completed continuously and progressively throughout the life of a mine. The costs associated with these restoration activities can be substantial: One estimate suggests US million per mine, although varied mine sizes, regulatory regimes, or the
