process flowsheet into which the new separation process is inserted. After the initial leaching process of the nickel ore or concentrate, and subsequent liquid/solid separation, purification is needed to remove: a) Copper, if present in commercial quantities, by solvent extraction.
The most effective method of isolating the Cu minerals is froth flotation. This process causes the Cu minerals to become selectively attached to air bubbles rising through a slurry of finely ground ore in water (Fig. 1.4).Selectivity of flotation is created by using reagents, which make Cu minerals water repellent while leaving waste minerals wetted.
Extracting copper from other ores. 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.

A typical ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony. After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony.
The concentrate will be processed in a pressurized vessel where it will react with oxygen and sulphuric acid to produce an impure solution of nickel, cobalt and copper. This solution will pass through a number of chemical purification steps ending with removal of impurities and separation of nickel, copper …
Iron oxide copper-gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) …

Mount Isa Mines operates two separate mining and processing streams, copper and zinc-lead-silver, near Mount Isa, Queensland, Australia. Its copper operations include two underground copper mines, Enterprise and X41, with ore mining capacity of 6.2 million tonnes per annum (Mtpa), a concentrator with 7Mtpa capacity, a copper smelter, and support services.
Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
Copper Processing Plant description: There are mainly three types of copper ore: sulfide type copper ore, oxide type copper ore and mixed ore. Based on abundant experiences on copper mining project, Prominer supplies customized solution for different types of copper ore. General processing technologies for copper ore are summarized as below:
Separating Copper Ore Australia Cone Crusher Turkmenistan Copper Ore Crushing Production Line Mobile Crusher After primary crushing the material will transferred to cone crusher by belt conveyor for secondary crushing; the crushed copper ore stone will then transferred to vibrating screen for separating.
Converter - In copper smelting, a furnace used to separate copper metal from matte. Core - The long cylindrical piece of rock, about an inch in diameter, brought to surface by diamond drilling. Core barrel - That part of a string of tools in a diamond drill hole in which the core specimen is collected.
Separating Copper Ore Australia Mining Machinery Appliions. Ore processing is highly important particularly in the production of precious metals and non-precious metals. This process uses decanters in various mining applications gold and silver lead and zinc nickel and copper …
Geologists classify mineral deposits in many different ways, according to the: commodity being mined. tectonic setting in which the deposit occurs. geological setting of the mineral deposit. genetic model for the origin of the ore deposit. The most commonly used scheme is the genetic classification scheme.
nickel and copper anodes. 2. Electro-refining operations, where these anodes are dissolved electrolytically to produce pure nickel and copper and an anode slime containing the precious metals. 3. Chemical operations, for the separation and refining of the individual metals. Smelting Operations Converter matte from Rustenburg arrives
Production from the Thalanga deposit ceased in 1998, and the mining operations were placed on care & maintenance when the Thalanga mill was converted to process high grade copper ore from the nearby Highway-Reward deposit. From 1998 to 2005, 3.2Mt @ 6.2% Cu & 1 g/t Au of copper ore from Highway-Reward was processed through the Thalanga …
Feb 20, 2017· The mine produces over 1.1 million tonnes of copper ore and in excess of 185,000 tonnes of copper concentrate per annum. The concentrate contains approximately 29% copper and is …
The copper ore bodies mined from 1911 to 1938 at Kennecott, Alaska (now within the Wrangell–St. Elias National Park and Preserve), are examples of potentially environmentally "friendly" ore deposits. The ore bodies consisted of veins of massive chalcocite (a mineral consisting of copper and sulfur).

5. Copper may also be introduced during over phyllic-argillic alteration events. The general attributes of porphyry copper deposits are summarized below. Brief Description In hypogene parts of porphyry copper deposits, the copper occurs predominantly in chalcopyrite; other important copper ore minerals may include bornite and enargite.
Optical sorting and lasers are very well suited to the detection of ores with different colours, such as copper oxide, or crystalline structures in quartz. By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations.

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
