Copper sulfide ores are typically the most profitable types of copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted ...
Several different types of oxide and sulfide copper ores were tested in this study. Table 1 gives a description of these samples. Assaying of Samples. This study required that a large number of copper, ferrous and ferric iron, and free-acid analyses be made.
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
A NEW TYPE OF COPPER SULFIDE DEPOSIT FOUND IN TRANSFORMERS. ... Normal types of copper sulfide in transformers are of t he film and nodule morphology as shown in Figure s .
The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper that is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver).
The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8.There is a resemblance to the cell of Fig. 7.
Specifying Copper Tube. Table 1 identifies the different types of copper tube allowable for use in fuel gas distribution systems in the U.S.A., along with the identification and availability of each type. Types K and L copper tube (ASTM B 88) and ACR tube (ASTM B 280), up to and including 1-inch outside diameter, have been used in fuel gas systems for many years.
Beside the ores containing copper mainly as sulfide, with a small amount of oxidized copper, many of the large porphyry mines have oxide orebodies, in which the proportion of non-sulfide minerals is so high that present methods of treatment are inefficient.
The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper…
Apr 23, 2011· There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ...
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.
The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals with varying percentages of copper in the chemical formulas of those minerals. The richest grade of copper ore is native copper, which is pure copper (). Many metallic ores occur as sulfide minerals.
Copper sulfide belongs to a family of chemical compounds and minerals with the formula CuxSy. It can be classified into three groups, namely monosulfide, disulfide and mixed monosulfide. Copper sulfide occurs naturally in nature as a mineral called covellite. It conducts electricity moderately. Both ...
There are two distinct types of copper deposits: sulfide ore and oxide ore. Currently, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 ...
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.

The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS).
May 29, 2019· These results highlight that nanostructuring is an effective approach to overcome kinetic limitations of conversion-type copper (II) sulfide cathodes that are observed in the bulk system.
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 will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in …
Prominent copper sulfide minerals include Cu 2 S and CuS . In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper …
Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. Occurrence. Chalcopyrite is the most important copper ore.
Mar 19, 2018· Copper sulfate is found in many products that you may use throughout your life. Its primary use is as a component of fertilizers, as a pesticide, but rarely will you find it in your everyday cleaning products. Copper sulfate can be toxic if taken in a large enough quantity, but poisoning rarely occurs unless it is consumed through oral ingestion.
Bruce Brown, Jeremy Moloney, in Trends in Oil and Gas Corrosion Research and Technologies, 2017. 15.2.2 Conductive deposits. Iron sulfides are probably the most encountered semiconductive deposit types in oil and gas production and transmission pipelines. Numerous iron sulfides can exist, the nature of which is dependent on the environment and operating parameters.
