Copper Ore Gangue

Copper extraction - Wikipedia

Copper extraction. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste (gangue) minerals. It is then concentrated using mineral flotation.

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. stone reagents called ...

Gangue | geology | Britannica.com

In copper processing: Mineral processing …from the waste materials, or gangue. In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground only to the extent required to expose the surface of…

Copper Ore Types: Sulfides vs. Oxides | INN

Copper-containing rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.

Copper ores - Danafloat

The gangue particles can consist of a range of silicate minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated, typical copper sulphide minerals are relatively easy to float. When there are no overriding metallurgical issues, producing a sufficiently high copper concentrate grade is often the focus.

UNDERSTANDING ACID CONSUMPTION AND ITS …

UNDERSTANDING ACID CONSUMPTION AND ITS RELATIONSHIP WITH COPPER RECOVERY M. L. Free, Univ. of Utah, Salt Lake City, UT ABSTRACT Acid consumption in copper heap leaching is determined by the minerals present in the ore. Gangue minerals such as biotite and chlorite consume acid together with copper-bearing minerals such as chrysocolla and malachite.

OVERVIEW OF GANGUE MINERALOGY ISSUES IN OXIDE …

considered in maximizing the efficiency of copper recovery and minimizing the consumption of acid by gangue. The following review lists the major gangue and ore minerals that may be present, and highlights some of the more important mineralogy issues involved in leaching oxide copper ores.

Question: A Treated Ore Containing Inert Solid Gangue And Copper Sulfate Is To Be Leached In A Countercurrent Multistage Extractor Using Pure Water To Ieach The Du.CuSO_4. The Solid Charge Rate Per Hour Consists Of 10 OOO Leg Of Inert Gangue (B), 1200 Leg Of CuSO_4 (solute A) And 400 Leg Of Water (C) The Exit Wash Solution Is To Contain 92 Wt % Water And 8 Wt ...

Whats is the price in dollars for 5% copper ore? - Quora

Jan 08, 2019 · The price of the ore depends on two things: (1) the value of the copper it contains, minus (2) the cost of recovering that copper (mostly excavating it from the ground, separating it from the gangue minerals, recovering it as metal, and getting it...

Gangue - Wikipedia

Gangue. It 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. It’s a worthless rock but contains valuable material.

Copper mining. From ore to copper.

The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass.

Copper processing - Ores | Britannica.com

In the ore-dressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, or gangue. In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not ...

What is the difference between gangue and ore? - Quora

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

examples of iron ores and the gangue

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS) , liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate , Gangue slimes (typically clays and talc) can be an issue because of .
