Copper extraction - Wikipedia

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

20.1 Metal Deposits – Physical Geology

When ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate. At a molybdenum mine, for example, this concentrate may be almost pure molybdenite (MoS 2). The rest of the rock is known as tailings. It comes out of the ...

Host Rock - Mining Fundamentals

Apr 29 2014. Host rock is, simply, the rock surrounding the ore deposit. Host rocks, as the definition suggests, may be found as a host to any kind of ore deposit, from gold to uranium. Host rock may also be defined as the type of rock where mineralization occurs. Host rocks are significant in identifying the age of the mineral deposit.

Host Rock - an overview ScienceDirect Topics

The host rocks are sedimentary rocks of the Marquette–Baraga Supergroup comprising slates, iron formations, quartzites, and older cherty carbonate. The main Bovine intrusion is composed of a large gabbroic inner core with two thin rims in succession. The inner core (upper unit) is composed of fine-grained gabbro with thickness varying between 30 and 150 m.

Copper processing - Ores Britannica

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

The Geology of Rare Earth Elements

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...

ore National Geographic Society

Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.

PorterGeo Database - Ore Deposit Description

Ore zones occur as en echelon lenses up to 20 m thick, but averaging 2 to 3 m, and up to 100 m in length. They are confined to well defined zones along the thrust sub-parallel to the foliation in the host rock. In general uranium and copper ore lenses are separate, although usually close together.

Cobalt - PUB2893 Missouri Department of Natural Resources

Oct 07, 2020  Ores containing cobalt have been mined in the subsurface in the past. Ores were blasted, crushed, transported to the surface, crushed further, and separated from other metal ores, non-ore minerals, and host rocks in a mill. Ores were then smelted to generate cobalt metal. Resources

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

20.1 Metal Deposits – Physical Geology – 2nd Edition

Looking at copper, for example, we can see that while average rock has around 40 ppm (parts per million) of copper, a grade of around 10,000 ppm or 1% is necessary to make a viable copper deposit. In other words, copper ore has about 250 times as much copper as typical rock.

The concentration of nickel and copper in the sulfides varies systematically across the ore deposit. The nickel content of iron-nickel sulfides varies between 2-5 and 3 per cent in the hanging-wall ore but increases regularly from 3 per cent to 5 or 5-5 per cent from hanging wall to footwall across the main-zone ore.

Azurmalachite: A rock composed of azurite and malachite

Slightly acidic, copper-bearing waters percolate downwards through fractures and pore spaces in the rock. During their descent they encounter a geochemical environment that allows the precipitation of carbonate minerals, and that is where the azurmalachite forms. The host rock is often a carbonate rock, such as limestone or marble. These ...

Stamp Mills for Processing Gold Silver Copper Ore

A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining. The basic design of a stamp mill has been used for thousands ...
