mineral resource A concentration or deposit of minerals in the earth's crust which is potentially valuable native copper An uncombined (pure) form of copper which occurs as a natural mineral Copper is one of the few metallic elements to occur in native form although it most commonly occurs in oxidized states and mixed with other elements Most widespread minerals containing Copper This list of minerals containing Copper is built from the mindat locality database This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Copper mineral species

Copper Sulfide Ore

The concentration of these minerals in an ore body is low Typical copper ores contain from 0 5% Cu (open pit mines) to 1 or 2% Cu (underground mines) Cu-Fe-S minerals are not easily dissolved by aqueous solutions so the vast majority of copper extraction from these minerals is pyro-metallurgy (Excerpt from Extractive Metallurgy of Copper)

Metal sulfides are the most important group of ore minerals Here we review what is known about their compositions crystal structures phase relations and parageneses Much less is known about their surface chemistry their biogeochemistry or the formation and behaviour of 'nanoparticle' sulfides whether formed abiotically or biogenically

Group of minerals that are compounds of one or more metallic elements combined with the non-metallic element sulfur The sulfur acts as a semi-metal when it combines to form a sulfide mineral In some sulfides the semi-metals arsenic antimony selenium and tellurium substitute for the sulfur

For special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper this mineral can be recovered by a simple gravity circuit Application Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper iron and sulfide

Likewise copper and PGE do not easily partition into silicate minerals but they readily enter magmatic sulfide with copper entering sulfide with a partition coefficient of about 2000 Pt with a coefficient of about 20 000 and Pd with a coefficient of almost 100 000 (Peach et al 1990)

Direct extraction of copper from copper sulfide minerals

Whilst some copper ores are amenable to hydrometallurgy chalcopyrite the main copper mineral is challenging to process in aqueous solutions due to surface pa Jump to main content in Deep Eutectic Solvents can solubilise and directly recover high purity copper from solution from three copper sulfide minerals covellite (CuS

The sulfide minerals and the PGMs are isolated together in concentrates mostly by froth flotation This is because the PGMs occur (a) as mineral grains of PGMs in or near mineral grains of iron nickel and copper sulfides and (b) in solid solution in the sulfide minerals containing iron nickel and copper – particularly in pentlandite

Luster the way a mineral reflects light is the first thing to observe in a mineral Luster can be bright or dull but the most basic division among the various types of luster is this Does it look like a metal or not?The metallic-looking minerals are a relatively small and distinctive group worth mastering before you approach the nonmetallic minerals

Disclosed herein is a method for concentrating gold contained in a leach residue obtained in a copper hydrometallurgical process for recovering copper from a copper sulfide mineral to efficiently separate and recover gold from the leach residue According to the method a gold-bearing copper sulfide mineral is subjected to pressure leaching with sulfuric acid at a temperature higher than 102

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 and sulfur

Such minerals may contain high concentrations of lead zinc and copper usually in sulfide minerals like galena (lead sulfide) sphalerite (zinc sulfide) and chalcopyrite (copper-iron sulfide) Since they are included within the sedimentary strata they are called stratabound mineral deposits

For special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper this mineral can be recovered by a simple gravity circuit Application Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper iron and sulfide

Organic sulfides are compounds in which sulfur is bonded to two organic groups Inorganic sulfides are ionic compounds or salts which contain a negatively charged sulfide ion Phosphine sulfides occur when the sulfur atom reacts with organic phosphines Examples of sulfides include zinc copper

How to Extract Precious Metals From Sulfides

Employ bioleaching for base metals such as zinc copper and nickel or mineral bioxoidation to enhance extraction of gold and silver Both methods rely on bacterium such as hiobacillus ferrooxidans to recover precious metals For example stack ore in piles 200 feet deep Apply water-diluted sulfuric acid to enable bacterium to grow

Dec 06 2016Sulfides can be found throughout nature and are part of the natural cycle of life Geologically the Sulfide Class of minerals comprise an economically important class of minerals Most major ores of important metals such as copper lead and silver

At first glance sustainability and mineral resource development appear to be in conflict Mining depletes finite resources and in a strict sense therefore is inherently unsustainable For instance there is only a finite amount of copper in the earth's crust and each unit of copper extracted

Copper ores have been mined for at least 5 000 years because it is easy to get the copper out of them For example if a copper oxide ore (CuO) is heated in a wood fire the carbon in the charcoal can reduce the oxide to metal Making pure copper Extremely pure copper (greater than 99 95%) called electrolytic copper can be made by electrolysis

Copper Sulfide Properties Risks and Uses The Copper sulphides Describe a family of chemical and mineral compounds with the formula Cu X S Y These compounds comprise economically important minerals and synthetic materials The most prominent copper sulphide minerals include copper (I) sulfide or cuprous sulfide

For example chalcopyrite cuprite bornite - copper-bearing minerals occurring together Most often ore bodies of sulphide deposits have the form of veins But there are also lenticular stock reservoir forms of occurrence Sulphide application Sulfide ores are extremely important as a source of rare noble and non-ferrous metals

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores There are several copper ores but they all fall into two main categories oxide ores and sulfide ores Oxide ores contain oxygen Sulfide ores contain sulfur Azurite malachite and chrysocolla are a few examples of oxides ores

(FeO SiO 2 can also represented as FeSiO 3) After the slag is removed the resulting product called matte is a mixture of copper sulfides (mostly Cu 2 S) and impurities such as iron sulfides This matte containing about 40% copper can then be fed to a converter
