Sediment-hosted copper deposits are stratabound, that is, they are restricted to a narrow range of layers within a sedimentary sequence but do not necessarily follow sedimentary bedding. They are epigenetic and diagenetic, that is, they are formed after the host sediment is deposited, but in most cases, prior to lithification of the host.
Chalcopyrite has a golden yellow color, which often resembles Gold.However, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it. Chalcopyrite is a beautiful mineral, with good crystals being fairly common.

a mining company must show how they will reclaim the mine before mining activities begin, and they must obtain a permit for their activities. If they fail to reclaim the land, they may face a fine, be immediately stopped from mining, and be prohibited from getting future permits to mine.
Chalcopyrite Group. Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Zn-rich variety is known from Atlantis II Deep (see zincian chalcopyrite).Also, the Mid-Atlantic-ridge isocubanite may transform to ...
It is then fed into a bath of water containing a ing agent which produces a kind of bubble bath. When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of . They float to the surface making a froth. The unwanted waste rock (gangue) falls to the bottom and is removed.
Alabama is home to a diverse and widespread variety of minerals, with more than 190 mineral species occurring in the state. These minerals have played a key role in the development of the Bauxite state, beginning with the prehistoric period, when flint, mica, clay, and other rocks and minerals were used by Native Americans. The state's rich stores of iron-bearing hematite provided the raw ...
The Chalcopyrite is important sulfide, cope iron mineral naturally found in Kansas. It is golden yellow in color, and its hardness is between 3.5 and 4. Chalcopyrite is commonly found in both sedimentary exhalation deposits and volcanogenic massive sulfide ore deposits that are formed during the hydrothermal circulation when copper is deposited.
Recent Finds - Yellow Brucite Feb 15, 2017 - The glorious yellow color of these finds is a first for brucite, to my knowledge.

'Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals.
Much of the Gold mined is from large mining operations where the Gold is smeltered for commercial use, and although many commercial gold mines exist, mineral specimens and crystals are hard to come across. China and South Africa have been the worlds two largest Gold producers, but collectors will rarely if ever see a Gold specimen from these ...
A fine grind to about 80% minus 15 microns was required to increase the reaction rate, and iron removal was around 50%-70% for chalcopyrite and 80%-90% for bornite. Experimental. Fine monosize particles, 2.5×5 µm, 5×10 µm, and 10×20 µm, were prepared from Pima concentrate by the Donaldson Company with an Accucut Model B air classifier.
Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
Some pyrites can contain 0.25% gold by weight or more. Although this is a tiny fraction of the ore, the value of gold is so high that the pyrite might be a worthwhile mining target. If pyrite contains 0.25% gold and the gold price is $1500 per troy ounce, then one ton of pyrite will contain about 73 troy ounces of gold worth over $109,000.
Another thing to consider, is that the gold within many ores is microscopic particles, which require advanced methods to extract, such as through cyanide leaching. Extracting gold from this type of ore is feasible for multi-million dollar mining companies, but almost impossible for the average person to do.
