Copper Ore Oxidized

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores the oxidized ores consisting of the silicates carbonates and sulfates are treated by several methods all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate

Fast fact a prime example of copper oxidation is the statue of liberty wherein a green color has developed on the structures surface due to redox and not due to effect of acid rain as generally believed by ing to the copper development association until now the oxidation of the statues copper skin is about 0005 inch

Copper processing copper processing roasting smelting and converting once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements in older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractorylined furnace of either the hearth or

Mar 17 2017 the oxide minerals are compounds of metallic elements plus oxygen with two prominent exceptions ice and quartz ice h 2 o always gets left out of the mineral books quartz sio 2 is treated as one of the silicate of them are primary minerals that solidify deep in the earth in magmas but the most common oxide minerals form near the surface where oxygen in the air and

Ammonia leaching is a promising method for processing lowgrade copper ores especially those containing large amounts of oxidized copper in this paper we study the effect of sicontaining

Sulfide copper concentrate from domestic ore deposit bor serbia was subjected to oxidation in the air atmosphere due to a better understanding of reaction mechanism and oxidation of various

Oxidized copper ore studies on leaching of oxidized copper ore from a leaching study was conducted on south america oxidized copper ore assaying 310 cu and the process parameters were optimized including leaching temperature leaching time acid consumption

In this study the oxidized copper ore used was supplied from the ergani copper mining co turkey ergani which is in southeast turkey is a leading copper and pyrite ore production area analyses show that the ore obtained from the ergani region contains 203 copper 015 cobalt and 373 sulfur pyrite chalcopyrite and oxidized copper ore are

The invention discloses a method for extracting gold from copperoxide oxidized gold ores the method comprises the following steps 1 carrying out ammoniacyanide leaching on the copperoxide oxidized gold ores to obtain an ore pulp 2 adding hypochlorite into the ore pulp and stirring to remove copper in order to obtain a copper removed ore pulp 3 carrying out countercurrent washing on

An increasing share of copper is produced from acid leaching of oxidized ores copper is one of the oldest metals ever used and has been one of the important materials in the development of civilization because of its properties singularly or in combination of high ductility malleability and thermal and electrical conductivity and its

Some copper sulphide ores can be partially oxidized also influencing the selection of a reagent scheme copper sulphide ores are normally f iner grained than porphyry copper ores and require finer

Pressure oxidation pox is a process used to extract gold copper zinc molybdenum and uranium from refractory ore bodies the pox process utilizes elevated temperatures roughly 230 degrees celsius elevated pressures roughly 35 bar or 510 psi and oxygen to liberate the minerals from refractory ores

These mixtures work because the acid in the vinegar or lemon juice strips the oxidized patina from the copper and the salt acts as a mild abrasive to remove the grime you can also use lime juice instead of lemon ketchup grab a bottle of ketchup for the third natural cleaning idea yes ketchup

Oxidized ores in which malachite azurite and chrysocolla are the predominant copper minerals that do not respond either to gravity or simple flotation methods sulfidefilming of the carbonates followed by flotation of the filmed minerals or direct leaching followed by precipitation of the copper from the solution may be employed for such ores

The copper content of chalcopyrite is 34 and that of covellite 66 enrichment takes away copper from the upper part of an ore body and drops it off at the water table this process is called supergene enrichment the oxidized zone and zone of enrichment may contain profitable mineralization

The addition of 6494 depends on the content of copper oxide ore the ph should not be more than 10 the addition of soda ash could be useful to regulate the ph if you dont have a cleanerscavenger circuit try to include it this circuit can reduce part of copper lost in the cleaner tails

Apr 23 2011 oxidized copper ore bodies may be treated several ways with hydrometallurgical processes used to treat oxide ores dominated by soluble minerals such as copper carbonate minerals these oxide ores
