Materials recovered by mining include bauxite, coal, copper, gold, silver, diamonds, iron, precious metals, lead, limestone, nickel, phosphate, oil shale, rock salt, tin, uranium, and molybdenum. Any material that cannot be grown from agricultural processes, or created artificially in a laboratory or factory, is usually mined. Mining in a wider sense can also include extraction of petroleum, natural gas, and even water.<BR/><BR/><BR/>Procedure<BR/>Steps of process<BR/>1.Prospecting to locate ore. <BR/>2.Exploration to find and then define the extent and value of ore where it is located ("ore body"). <BR/>3.Conduct resource estimate to mathematically estimate the extent and grade of the deposit. <BR/>4.Conduct mine planning to evaluate the economically recoverable portion of the deposit (and including reclamation planning). <BR/>5.Conduct a feasibility study to evaluate the total project and make a decision as whether to develop or walk away from a proposed mine project. This includes a cradle to grave analysis of the possible mine, from the initial excavation all the way through to reclamation. <BR/>6.Development to create access to an ore body <BR/>7.Exploitation to extract ore on a large scale <BR/>8.Reclamation to make land where a mine had been suitable for future use.<BR/><BR/>Techniques<BR/> <BR/>A minecart toilet, used in Bisbee, Arizona.Mining techniques can be divided into two basic excavation types:<BR/><BR/>1. Surface mining <BR/>Open-pit mining <BR/>Quarrying <BR/>Strip mining <BR/>Placer mining <BR/>Mountaintop removal <BR/> 2. Sub-surface mining <BR/>Drift mining <BR/>Slope mining <BR/>Shaft mining <BR/>Hard rock mining <BR/>Borehole mining <BR/>Drift and Fill mining <BR/>Long Hole Stope mining <BR/>Sublevel Caving <BR/>Block Caving <BR/>Shrinkage Stope mining <BR/> <BR/><BR/>Solution mining is a particular mining technique that is used to mine minerals (potash, potassium chloride, sodium chloride, sodium sulphate) which dissolve in water.^^VRINDA CHHABRA^^https://www.blogger.com/profile/07361705132233333845noreply@blogger.com
