High Sulphur Concentration In Copper Ore

Copper can be extracted from nonsulphide 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 copperii sulphate solution concentration of the copperii sulphate solution by solvent extraction

Recovery of iron from a highsulfur and lowgrade iron ore 20180410 highsulfur iron ore was grinded and sieved through 50 mesh screen 300 m opening iron and sulfur contents of dried powder were determined by chemical methods because xrf analysis is not accurate for sulfur containing ores

Aug 01 2015 a novel ore preconcentration technique using high voltage pulses is proposed metalliferous graininduced breakage and sizebased screening for gradesplitting four copper ore samples were tested to demonstrate the viability of this technique the pulse energy transfer efficiency may be used to infer particle grade

Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from antofagasta chile was investigated after leaching with a chlorideferrous media at two temperatures the study focused on whether this chemical leaching system could be applied at an industrial scale leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore the

Different methods are used to process copper sulfide ores depending on the concentration of copper within the ore higherconcentrated ores can be separated via smelting while lower

How to remove sulfur and copper from iron ore copper mining and extraction sulfide ores from the formula it is clear that iron and sulfur have to be removed in order to produce copper the roasting process changes some of the cufes 2 to copper oxide removes some of the sulfur as sulfur dioxide this is done by heating the concentrated ore from froth flotation it is heated to between 500 176 c

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

The invention belongs to the field of mineral processing relates to a beneficiation method and particularly relates to a method of sorting copper sulfide ore flotation tailings the method comprises the following steps a the tailings with copper and sulfur separated are dewatered through a thickener wherein the content of the sulfur in the tailings is more than 20 and the concentration

Keywords sulfur removal chemical leaching iron ore concentrate introduction a highgrade magnetitehematite iron ore deposit is located in the golegohar mine sirjan kerman province in iran the geological proven reserve is about 1200 tg teragram and the golegohar complex provides the production of 5 tg concentrates per year

Leaching of copper oxide ore than high ph values ph greater than 1 the leaching of copper leaching solution and sulfur concentration in the mattes did not much affect the leaching

Sep 26 2019 virtually all sulfidetype copper ores including chalcocite cu 2 s chalcopyrite cufes 2 and covellite cus are treated by crushing the ore to a fine powder it is concentrated by froth flotation which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic

Stage 3 roasting at this stage of the process the chemical reactions begin they convert the copper minerals into copper metal we can illustrate the types of process using the example of chalcopyrite cufes the formula it is clear that iron and sulfur have to be removed in order to produce copper

However as the concentration of copper in the ore bodies decreased the energy costs of smelting the whole ore also became prohibitive and it became necessary to concentrate the ores first initial concentration techniques included handsorting and gravity concentration they resulted in high losses of copper

Nov 8 2016 the plant continued milling and concentration of lead ore from 1958 until two midvale copper smelters treated highsulfur ores from bingham get price removal of sulfur and phosphorous from iron ore concentrate by keywords sulfur removal chemical leaching iron ore concentrate

Flotation separation of high sulfur leadzinc ore abstract the ore is the oxide ore of copper lead and zinc the ore has high oxidation rate of pbnearly 50 which contains 356 of pb386 of zn0209 of cu the flotation flowsheet consisting of the scene is part of the mixed flotationinhibitor zn and pb

High copper and mercury recovery from the pilot leach residue was also assessed with elemental sulphur flotation of the residue bismuth adversely affects the drawability of copper wire even at low levels and its concentration in the refined copper must be kept to less than 05 ppm

However as the concentration of copper in the ore bodies decreased the energy costs of smelting the whole ore also became prohibitive and it became necessary to concentrate the ores first initial concentration techniques included handsorting and gravity concentration they resulted in high losses of copper

The conglomerate ore analyzed approximately 12 copper the specific gravity of the ore was 272 and the bulk density was 108 pounds per cubic foot determined on as is ore the bond laboratory ball mill work index was determined as 220 at 65 mesh autogenous grinding tests crude ore was fed manually to the mill wet ground and discharged through slotted grates and five pebble slots

The latter are complex copper iron and sulphur mixtures in combination with other metals such as arsenic zinc and silver the copper concentration in such ores is typically between 052 the commonest ore is chalcopyrite cufes 2 a brass yellow ore that accounts for approximately 50 of the worlds copper deposits

Looking at copper for example we can see that while average rock has around 40 ppm parts per million of copper a grade of around 10000 ppm or 1 is necessary to make a viable copper deposit in other words copper ore has about 250 times as much copper as typical rock
