The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul
Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground’s surface, and about two thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining

Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material.
After mining, the first major step in copper refining is concentration. This crucial process, which is generally conducted at or very near mine locations (to save on transportation costs), involves grinding mined ore to
The refining process begins with crude oil. Crude oil is unrefined liquid petroleum, which ranges in color from yellow to black, and may have a paraffin, asphalt or mixed base. Crude oil is composed of thousands of different chemical compounds called hydrocarbons, all with different boiling points. For example, a typical crude oil may
The Ore Extraction and Refining Process Before iron ore can be used in a blast furnace, it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs, this young iron puddler's helper posed for this photograph in the early 1860s, when the Sons of Vulcan was a young union. (From the collections of
The refining process also rearranges their structures and bonding patterns into different hydrocarbon molecules and compounds. Therefore it is the type of hydrocarbon (paraffinic, naphthenic, or aromatic) rather than its specific chemical compounds that is significant in the refining process.
#173;The final stage of gold production refining involves removing impurities that remain after the smelting process. Refining companies receive dor#233; bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure
Removing the gold bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to
