LEACHING OF LOW-GRADE COPPER ORES: A CASE STUDY

The changes in copper content in the ore with the time of exploitation at the RTB mines [9] Oxide copper ore, mixed oxide-sulphide ores and low-grade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper

Agitated Copper Leaching & Cementation Process

Apr 14, 2016 Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations.

US4039405A Leaching copper ores and solvent

This invention relates to a process whereby recovery of copper from copper ores using leaching and solvent extraction techniques can be increased. The process generally comprises leaching to obtain a pregnant leach liquor, washing ore residues with an extra quantity of water to obtain extra dissolved copper values, recovering said copper values, combining the extra wash water with the pregnant

Acid leaching of a copper ore by sulphur-oxidizing

Aug 01, 2014 A maximum of 88% copper extraction was obtained after 9 weeks of leaching when 13.3 kg S o was added/t ore. This approach to leaching of copper ores that contain appreciable acid-soluble copper may be applicable where transportation of sulphuric acid is hazardous or expensive and a local supply of elemental sulphur is available.

(PDF) A STUDY OF LEACHING OF COPPER OXIDE ORE BY

Mexican copper ore is a mixed ore containing mainly copper oxide and some copper sulfide that responds well to flotation. The joint techniques of flotation and leaching were studied.

Gold and copper leaching from gold-copper ores and

May 01, 2017 Gold-copper ores: gold-copper oxides. The gold extraction from leaching gold-copper oxides ore, containing 12.9 ppm gold and 0.04% copper, has been studied. The copper in such ore is present at nuisance levels, meaning that copper presence adds additional cost for treatment without bringing any additional revenue.

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lac

Platinum-Group Metal an overview ScienceDirect Topics

The platinum group metals occupy the second and third rows of periodic table Group VIII, the first row of which consists of iron (Fe), cobalt (Co), and nickel (Ni). The second-row elements ruthenium (Ru), rhodium (Rh), and palladium (Pd) all have the krypton (Kr, inert gas, atomic number 36) core of completed electron shells and subshells ( see

Iron seems to be a very cheap metal to use as a collector, but plasma arc melting should be used to smelt iron and catalytic converters without flux.

Platinum group Wikipedia

The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).

US4571262A Recovery of platinum group metals from nickel

A process for separately recovering platinum group metal values, nickel values and copper from nickel-copper-iron sulphidic matte containing platinum group metals includes leaching ground matte at atmospheric pressure in acidic nickel-copper sulphate solution at a temperature in the range of from about 75° to about 105° C. and at a pH below about 4 initially under oxidizing conditions and

What Are Platinum Group Metals (PGMs)? ThoughtCo

Dec 10, 2018 The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

Extraction and Refining of the Platinum Metals Johnson

From this stage onwards the concentration of the platinum group metals is more rapid and the processes entirely chemical. First the slime is subjected to roasting and leaching attacks to remove the last of the copper, nickel, iron and sulphur. This produces an enriched slime running approximately 65 per cent of the platinum group metals and gold.
