Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds. Even after extraction, the rough diamond is still far from being set in an engagement ring.
Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. Gold Heap Leaching Process Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution.

Nov 16, 2013· Diamonds are used for many purposes other than just jewellery. Finding diamonds and their extraction is quite an art. They are not available at all places and once found their extraction must be carried out with utmost efficiency and care. Our today's article deals with how diamonds are extracted in Russia's region of Ural.
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 pieces no larger than road gravel.
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot ...
Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment includes excavators, draglines, drills, roof bolters, continuous miners, longwall miners, rock dusters, shuttle cars and scoops.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive. Surface Mining For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines.
Complete extraction of the ore is possible. Disadvantages: Caving may cause injury to surface structures or render unworkable other orebodies in the region. Mining the ore by breast stoping requires more drilling and blasting. Broken ore on the slice must be shoveled into barrows or …
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ore in a very specific way.
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.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
