Hematite is the most important ore of iron.Although it was once mined at thousands of locations around the world, today almost all of the production comes from a few dozen large deposits where significant equipment investments allow companies to efficiently mine and process the ore.Chat
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.Chat
Oct 25, 2016· Its analysis corresponded to the formula HgAu2Ag6Te6. Other gold tellurides and some native gold amalgams are occasionally met with. At Kalgoorlie, at the Cripple Creek district, Colorado, in Transylvania, in Boulder County, Colorado, and in many other localities, the value of the ore depends on the tellurides of gold contained in it.Chat
In some tests involving crushed ore from a vein, where the gold was 400 mesh and finer, the recovery was around 80% but that was due to the fact that gravity type systems do not typically do well in recovery of gold that is so small it is capable of staying in suspension in the water flow.Chat

Oct 05, 2016· Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.Chat

May 05, 2017· By testing only the best looking ores, the results will often show (inaccurately) that the ore is valued at several ounces per ton, which would be a very rich gold mine indeed. Unfortunately, when only select samples are tested instead of a comprehensive test of all the ore, it creates an inflated richness that is not reflective of the mine itself.Chat
