For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.
The room-and-pillar involves extracting the rock by carving a series of rooms while leaving pillars of rock to support the mine roof. When mining reaches the end of a section of deposit called a panel, the direction of mining is generally reversed (called the "retreat") in an attempt to recover as much of the rock from the pillars as possible.
Some mining companies have very large equipment, which can handle hundreds of tons or rock an hour. These businesses can effectively go after ores of lower grade materials because of the high volume they can process. For the average prospector, though, it's not feasible to crush down a ton of ore for only a few grams of gold.
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Rock Duster. Rock dusters are pressurized pieces of equipment that coal miners use to spray inert mineral dust over highly flammable coal dust. The inert dust helps prevent accidental fires and explosions. Shuttle Cars and Scoops. Coalminers use electric-powered shuttle cars to transport coal from the coal bed to safer points in the mine.
