copper ore concentration process in australia

Copper extraction Wikipedia

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores

Olympic Dam Copper-Uranium Mine, Adelaide, Australia

Copper cathode sheets are transported by truck within Australia and to Port Adelaide for export. All uranium oxide produced at Olympic Dam is exported. The gold plant became fully operational in 2000. A fire in 2002 at the solvent extraction / electrowinning plant cost over A$300m to repair, while WMC also spent A$127m on renovating the copper smelter during 2003.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

copper extraction and purification chemguide

Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction.

Copper mining. The main stages.

Imagine a copper ore that contains 1% copper by mass. After concentration, this rises to 25%. 1 tonne of crude ore will produce kg The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting: This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500 °C and 700 °C to

Froth flotation Wikipedia

His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is uncertain if his

Nickel Geoscience Australia

In some deposits the Ni is associated with concentrations of platinum-group elements (PGEs) and copper, which increase the value of the nickel ore deposits. For example, the Noril’sk Ni-Cu-PGE deposit in Russia is estimated to have a value of approximately $1 trillion, representing one of the most valuable deposits in the world. Most of Australia’s nickel sulfide resources occur in Western

Copper Geoscience Australia

The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60%

Copper processing Ores Britannica

The greatest known reserve of copper ore in one body is the deposit at El Teniente mine in Chile. Many lesser deposits are being exploited, such as those in Canada, China, Australia, and Europe. Mining . For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for

How copper is made material, used, processing, steps

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate

How Hydrometallurgy and the SX/EW Process Made

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form
