Contains arsenic and lead sulfide in copper concentrates. Insoluble in water and denser than water. Primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Byproduct of manufacturing processes. Properties
Copper concentrate is a concentrated form of the raw copper mineral which is used to produce copper. The copper concentrate from Prominent Hill Mine contains 30 to 60 per cent copper and a mix of other materials sulphur, iron, silica, lead, aluminium oxide and less than
A copper flotation concentrate is over limit on Fluorine (F) content and Contamination. When assaying and plotting Copper (Cu) from times concentrates and the related fluorine and Magnesium Oxide (MgO) assays in various ways as shown below; one can see the obvious relationships.
We analyzed two copper and lead flotation concentrates from the LaRonde mill using MLA technology (Mineral Liberation Analyzer) to identify the contaminants and to quantify their size and liberation.
George Bedinger, mineral commodity specialist for the U.S. Geological Survey, prepared the following information on arsenic.. Arsenic is a gray metal rarely encountered as a free element, but is widely distributed in minerals and ores that contain copper, iron and lead.
record 74,000 t of copper in 1998, a 5% improvement over the 1997 record. The smelter processed 549,000 t of copper concentrates from other Cyprus operations. The refinery produced 172,000 t of cathode, and the rod plant operated above capacity and produced 139,000 t of copper rod in 1998, both amounts were new records.

solid copper sulfide, the solid residues are appropriate for the treatment in the conventional pyrometallurgical technology of smeIting/converting. Other common copper sulfide minerals usually present in copper concentrates, such as chalcopyrite, bornite, covellite, chalcocite, etc.,
The copper mining industry is an important source of wealth and employment in Arizona (AZ Mining Assoc., 2011). Yet, without proper planning and environmental monitoring, mining can also be a source of contamination that impacts the health of neighboring communities
contamination of the soil surrounding a smelter also is of concern. Fortunately, toxic metals are present only in very small concentrations in most domestic copper ores.4 Only Asarcos El Paso smelter currently treats concentrates that are con sidered to have high levels of volatile impurities. s The Anaconda Butte and Asarco Tacoma smelters
containing arsenic alongside copper. The possibility is demonstrated of selective copper and arsenic leaching into solution. It is confirmed that with autoclave leaching arsenides are broken down better than for natural arsenic containing minerals. Keywords leaching, matte, concentrate, copper, arsenic.
Las Bambas has mineral reserves of 7.2 million metric tons of copper and mineral resources of 12.6 million metric tons. The mine's operators estimate that in coming years, more than 2 million metric tons of copper will be produced in concentrate.
Pyrometallurgy, or smelting, is used on ore with copper sulfide and iron sulfide minerals. The concentrate is dried and fed into a furnace. The minerals are partially oxidized and melted, resulting in segregated layers. The matte layer refers to the iron copper sulfide mixture which sinks to the bottom.
TENORM Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
Effects of Exposure to Copper. Coppers bioavailability and toxicity to aquatic organisms can vary depending on the water body. It tends to be more toxic (more bioavailable) in water bodies that are low in dissolved minerals or organic matter, such as Lake Superior and its tributaries.
transportation of concentrates. There are fourteen high pressure copper concentrate slurry pipelines in operation, some as long as 300 km. The longest and largest of these was recently constructed in South America, to move copper and zinc concentrate from the mine site, at elevations as high as 4,200 meters, to sea level.
Copper.Production of copper concentrate by Mamut Copper Mining Sdn. Bhd. from the Mamut Mine in Sabah increased to about 107,000 mt from 100,129 mt in 1993. According to the Department of Mines, the average content of copper in the concentrate dropped from 25.1% in 1993 to 23.8% in 1994. The average content of gold and silver in the
The mine produces over 1.1 million tonnes of copper ore and in excess of 185,000 tonnes of copper concentrate per annum. The concentrate contains approximately 29% copper and is exported to

traces of combined copper in a few slag particles. This copper may, however, be associated with copper bearing sulfides and/or secondary copper minerals that formed after the slag production. Sample No. 11 This sample contains noticeable amounts of metallic copper (Fig. 3). In addition, there are secondary copper minerals (probably malachite).
fluorine bearing minerals in samples of final copper concentrates and the distribution of fluorine amongst the minerals. Quantification of each mineral in mill feed and various flotation streams at Ok Tedi enables an understanding of the quantitative response of fluorine bearing minerals to flotation.
The onus is to move back to concentrate producers to remove toxic elements, such as arsenic, earlier in the concentrate supply chain. The common copperarsenic bearing minerals in copper ores, enargite (Cu 3 AsS 4 ) and tennantite (Cu 12 As 4 S 13 ), contain significant amounts of
Second, liberated contaminants, specifically sphalerite, were observed in the copper concentrates. A relationship between copper deportment as chalcopyrite and bornite in the feed and zinc contamination in the copper concentrate was observed. Activation of sphalerite through dissolving of covellite and possibly tennantite/enargite is hypothesized.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which

The common copper arsenic bearing minerals in copper ores, enargite (Cu3AsS4) and tennantite (Cu12As4S13). contain significant amounts of copper 48.4% and 51.6% respectively.
Copper Concentrate is an ionic liquid mineral dietary supplement in concentrated form. Each serving of Copper Concentrate contains 3 mg (6,000 ppm) of copper as cupric sulfate. Copper Concentrate contains no artificial colors, flavors, sugars, stimulants or
Mining and extraction of copper by common surface or underground methods can concentrate and expose radionuclides in the waste rock (tailings tailingsThe remaining portion of a metal bearing ore after some or all of a metal, such as uranium, has been extracted.). Another extraction method, known as in situ leaching, can transport uranium and thorium into ground water or surface water at the site.
