28-5-2020· As with oxide ores, SX-EW tech is used to recover copper from a pregnant leach solution. Secondary sulfides, which are formed by supergene secondary …
Secondary copper recovery D. Davies Following a brief review of the economics of copper recycling, the technical details of secondary copper recovery are given, from classification and sampling of scrap through to the production of blister copper ready for electrolytic refining.
The recovery of these copper minerals ... This study was carried out to develop a flotation procedure for an oxide copper ore from a Region in Central ... but the secondary copper ...
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.
The acid consumptions curves for the oxide copper ore (number 3) with a high iron oxide-tactile gangue were somewhat different than those of oxide copper-porphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.
Secondary copper sulphides Low-grade ores are becoming increasingly important to metal production due to increasing metal prices and depletion of high-grade, low-impurity sources. Bioleaching can be an option to recover the metallic content present in these tailings. In this work, the bioleaching potential of a low-grade copper ore, containing

The ore deposit contains both primary and secondary copper minerals and is therefore classed into three distinct types, viz. sulphide, oxide and mixed. The mixed ore contains oxide, supergene oxide and hypogene sulphide copper species respectively with the greater part of the deposit being made up of sulphide and mixed ores.

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably ...
Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.

Copper ores (chalcopyrite, covellite and chalcocite) are mostly composed of other metals, besides copper. For instance, chalcopyrite mainly contains 26% copper, 26% iron, 33% sulfur and 2.5% zinc. Bioleaching of copper ore (chalcopyrite) is widely used in many countries.
Kansanshi copper mine is situated in the north western province of Zambia. As a result of the mineral variations, the processing plant treats three distinct ore types, viz. oxide, sulphide and mixed.
China dominates the iron ore, copper and soyabean markets, absorbing 60 per cent of traded supplies. It buys 30 per cent of globally traded fertiliser, 20 per cent of crude oil and coal and 17 per ...
