copper ore gangue

Copper extraction

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals The ore is then wet, suspended in a slurry, and mixed with xanthates or other reagents, which render the.

The major gangue minerals found in these copper ores are firstly listed and reviewed in terms of their relative reactivity with acid, and the factors affecting this.

What is the difference between gangue and ore?

Nov 28, 2017· Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore eg pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commercially.

The major gangue minerals found in these copper ores are firstly listed and reviewed in terms of their relative reactivity with acid, and the factors affecting this Taking into account the observations by various workers, a basic hierarchy is proposed for gangue.

Copper Ore Types: Sulfides versus Oxides

Apr 23, 2011· Copper-containing rock hosts only a small percentage of copper Most of the rock is unwanted material, typically referred to as gangue Depending on to what minerals the copper.


In mining, gangue (/ ɡ æ ŋ /) is the oft commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore depositIt is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals; a.

Copper Mining and Production Processes Explained

As well as the valuable copper there is much waste rock (called gangue) which has to be removed Copper mining The following gives an overview of how copper is extracted from its ore and converted into pure metal Mining The ore is removed from the ground in either open pit or underground min.

Copper production & environmental impact

Tailings are generated during flotation Tailings are made up of very fine host rock (ie, gangue) and nonmetallic minerals separated from the values during beneficiation The physical and chemical nature of tailings varies according to the ore characteristics and the beneficiation techniques used , The most commonly mined ore of copper.

How copper is made

Most of the copper ores mined in the United States contain only about 12-16% copper by weight The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore Chalcocite, Cu 2 S, is another sulfide ore Cuprite, or red copper ore, Cu 2 O, is an oxide ore.

Gangue minerals

The name, ore, appears to have been derived from the Middle English, oor, but its similarity to earlier names for copper ore and brass suggest a deviation Gangue is from the Greek, gang, meaning “vein of metal,” the form gangue being of French derivation.


Ores mostly consists of a mixture of minerals with useless or worth less rocky materials which are called gangue USES OF LEAD It is used in the preparation of Tel (C 2 H 5 ) 4 Pb tetra ethyl lead which is used to increase the efficiency of petrol.


Heavier clays and other silicates settle to the bottom of the tank This residue is known as 'gangue' The copper-laden froth is skimmed off Figure 4 Concentration of copper ore by froth flotation (b) Conversion of the sulfides and other copper compounds to copper The conversion is done by several methods: i) by roasting copper sulfide ores.

Types of Copper Deposits in the World

The average grade of copper ores in the 21st century is below 06 percent copper, with the proportion of ore minerals being less than 2 percent of the total volume of the ore rock.

Acid-Gangue Interactions in Heap Leach Operations: A

Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal Gangue, and its interaction with acid, plays an important role in such process Thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under.

12 Supergene Ore and Gangue Characteristics

In the traditional view, supergene ore and gangue minerals are the products of reactions between hypogene sulfide minerals and descending, acidic meteoric waters; these processes take place at or near the ground surface in subaerial environments (Guilbert and Park, 1986) In VMS deposits, copper and other metals are mobilized from primary massive.


Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of ac With the availability of real-time technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a mixed copper ore.

Iron Ore

Sep 16, 2013· Automated Hyperspectral Logging The successful development of iron ore resources is fundamentally linked to our ability to accurately identify not only multiple species of iron oxide minerals, but also sub-species, phases (eg ochreous vs hard) and associated gangue minerologi.

Copper Mining and Processing: Processing of Copper Ores

After the copper ore is crushed, liquid is added to make it a slurry The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”) The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue Chemical reagents called.


To liberate the copper-containing minerals from the gangue materials in the ore (Chapter 2) and enable them to be collected by flotation into a concentrate (Chapter 4), the ore should be finely ground.

Type of the Paper (Article
