The Mount Isa copper ore deposits are hosted within the Mesoproterozoic (1653 Ma) Urquhart Shale, an around 1000 m thick succession of carbonaceous, pyritic, dolomitic siltstone that belong to the Mt Isa Group, which lies within the Leichhardt River Fault Trough, and belongs to Cover Sequence 3 in the Western Fold Belt of the Mt Isa Inlier.
0.279% Cu + 0.150% Co (dolomitic shale)OREAS 550 - 10g. OREAS 550 was prepared from a blend of copper-cobalt oxide ore materials supplied by Metorex (subsidiary of Jinchuan Group) from the Dilala Est Copper Cobalt Project, located within the Kolwezi Klippe area of Lualaba Province (Democratic Republic of the Congo).
For the sandstone copper ores, the difference is small, while the dolomitic and shale copper ores provide very low values of the maximum practical content of Cu regardless of the theoretical. Low values of β p for the shale ore result from enhanced flotation of shale particles consisting of carbonaceous matter, clay minerals and certain …
Sediment-hosted stratiform copper deposits comprise disseminated to veinlet Cu and Cu-Fe sulfides in siliciclastic or dolomitic sedimentary rocks. Sediment-hosted stratiform copper deposits are extremely common though economically significant deposits are rare. They account for approximately 23 percent of the world's Cu production and known …
Copper-cobalt ores within the Kolwezi Klippe area are stratiform, sediment-hosted deposits hosted within Neoproterozoic sedimentary rocks of the Central African Copperbelt. Primary mineralisation typically consists of bornite, chalcopyrite and cobalt sulphides (linnaeite and carrollite) hosted within dolomitic argillite, shales, sandstone and ...

A decent-sized piece of rock containing the metal copper. — In-game description. Acquisition Gathering. Level 1 Mining from level 5 Mineral Deposit in Western Thanalan, south of Scorpion Crossing (X:26.8 Y:25.8); Level 1 Mining from level 5 Mineral Deposit in Central Thanalan, north of Steps of Nald (X:19.2 Y:26.5); Purchase
Some private individuals on contract to sell ore copper to the CMG Group until 2001 previously mined it. The project was abandoned for 5 years until later when the chief Mpande's son resumed the operation in the last quarter of 2006 to the first and second quarters of 2007. ... The dolomitic shale unit (SD) and the carbonaceous, silicified ...
The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ~50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist, 1978).Unlike the system for lead, the copper and …

The dolomite of most dolostones is granular, with the individual grains ranging in size from microscopic up to a few millimetres across. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimetres (0.079 and 0.24 inch) in greatest dimension. Vein dolomite grains may be up to several centimetres across.
The amount of copper in an ore can vary from 0.4 percent to more than 12 percent. Porphyry copper deposits, in which the copper materials are more or less uniformly scattered throughout the rock, account for the greatest …

Rock Composition. Dolomite rock is a sedimentary carbonate rock made of more than 50% mineral dolomite. Equal percentages of calcium and magnesium characterize it. Natural dolomite consists of around 44-50% magnesium and calcium, with some calcium substitution in magnesium layers. Some ancient dolomites also have small …
