72 intergrowths between sulfide and associated gangue silicate and oxide minerals. textures and 73 intergrowths in massive ores, semimassive breccia ores and other variants of sulfide74 dominated ores will be described inorthcoming companion paper.
The oxide orebodies, in which the copper is present about half as sulfide and half as oxidized minerals, and where the recovery to be expected is 25 or 30 lb. per ton of ore, might well be treated first by the method used at new cornelia, to recover the oxide copper, then reground and sent through the regular flotation operation.
Ore, while for microwaveirradiated leachingese values were 8.17 and 93.74 for sulfide and oxide. ores respectively. this showed the positive effect of microwave irradiation on copper.
Sulfide ores. the most common sulfide ore minerals are pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena, whereas the most common oxide ore minerals are hematite, magnetite, ilmenite, and chromite.
Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting. from sulfide ores. sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation.
Mixed oxide sulfide ores are becoming increasingly important in the u.s. for leaching using sxew technology. low grade chalcocite dominant orebodies in particular, are now recognized as amenable to leaching under certain conditions. however, the standard, commonly used methods to determine leachable.
Sulfide or laterite oxide resources. historically production has been dominated by sulfide ores but future production is increasing shifting to laterite ores. the principal reason for this historically is that sulfide ores are easier to process, through conventional mining, smelting and refining, compared to laterite ores which.
Sulfidebearing ores which can be treated using the process of this invention include sulfidebearing ores of molybdenum, zinc, iron, mercury, and copper. advantageously, the molybdenum oxide so produced from the sulfidebearing ore of molybdenum can be reacted further with lime and water producing calcium molybdate and hydrogen.
Copper sulfide and oxide ores are the forms most commonly mined for copper. copper ores. copper ores are complex. can contain metals, other elements, and nonmetallic minerals. in the ore, copper isess than 1. depending on the ore, it requires different mining and extraction processes to yield .
It is important to note that sulfide ores are not as abundant as the oxide difference. instead of the morrison copper gold project is located in the babine more detailed gold this isomplex gold ore with oxide gold inuartz vein with sulfide gold. if you are looking for gold and can not tell the difference between the second.
The concentrated ore must be converted intoorm which is suitable for reduction. usually the sulphide ore is converted to oxide before reduction. oxides are easier to reduce. thus isolation of metals from concentrated ore involves two major steps viz.,onversion to oxide, andeduction of the oxide to metal.
Differences in processing sulfide and oxide gold or gold nugget on pyrite notice pyrite has flat surfaces andrassy color gold has neither this isomplex gold ore with oxide gold inuart vein with sulfide get price ore processing waihi gold.
The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. for example, when copper is in the form of carbonate malachite, blue copper ore, the flotability is relatively good, while the flotability of silicate silica.

Properties of copper ores the problem minerals from which copper can be extracted to make money are called copper ores. there are several copper ores, but they all fall into two main categories oxide ores and sulfide ores. oxide ores contain oxygen. sulfide ores contain sulfur. azurite, malachite, and chrysocolla areew examples of oxides ores.
Oxide minerals and 34 as sulfide minerals mainly in the form of chalcocite and chalcopyrite. there are some industrial experiences of applyingrocess of chemical and then biological operation for such mixed oxidesulfide copper ores acevedo and jentina, 1993 sen et al., 1993. no considerations were taken for.
As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. however, in some cases lowgrade copper oxide ores can still be.
The results showed that the highest gold extraction was obtained on the high gold and low silver content of 79.0 for the oxide ore samples and 82.8 for the sulfide ore samples. the gold extraction on the oxide ores tends to be lower than the sulfide ores, and the gold extraction is dependent on the total amount of gold and silver in the ores.
Sulfide ores the most common sulfide ore minerals are pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena, whereas the most common oxide ore minerals are hematite, magnetite, ilmenite, and chromite.
In order to produceixed oxidesulfate product sulfation roastis preferred. the most outstanding example of this is found inthecommercial productionofzincby the hydrometallurgicalroute.roastreduction is aimed at producingetal directly by the interaction between the oxide formedin situand the unroasted sulfide. this is employed in the.
In this research, flotation of copper, lead and zinc minerals fromopper oxidesulfide ore was studied. the identification tests showed that the sample isixture of quartz, chalcopyrite.

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. first the copper ore frompen pit mine is blasted, loaded and transported to the primary crushers. then the ore is crushed and screened, with the fine sulfide ore 0.5 mm going to froth flotation cells for recovery of copper.
Crush, grind and classify the coppercontaining gold oxide ore. give the ore an alkaline treatment. add certain proportion of chelating agent and sodium cyanide to inhibit the leaching of copper and the selective leaching of gold. use conventional activated carbon in the leachate to adsorb gold. 4. gold sulfide ore properties of gold sulfide.
Lead oxide ore, mainly in the form of cerussite and anglesite, is originated from primary lead sulfide ore which gradually changed its property under efflorescence and carbonate salt environment. inead deposit, lead oxide and lead sulfide usually is detected at the upper layer and lower layer separately.
This present research work istudy about microwaveirradiation application for copper recovery from two main types of copper ores i.e., oxide and sulfide was investigated.

Ores in precolumbian times are unjustified, although archaeological evidence for the very effective wind furnaces described by early chroniclers is scanty. oxide and carbonate ores from shallow deposits are more simply smelted than the sulfide ores, which required roasting of the crushed ore prior to reduction atigher temperature.
Sulfation roasting,ommon activation technique, isotential method for cleaner production of nickel from complex lowgrade ores. in this study, nickel oxidesulfide mixed ore concentrate was roasted with the addition of ammonium sulfate undertatic air atmosphere, and the roasted products were leached by water, in order to evaluate the extraction of metals.
The mantoverde iron oxidecoppergold iocg deposit, chile, contains hundreds of millions of tonnes mt of mineable iron oxide and copper sulfide ore. while there is an agreement that mineralization at mantoverde was caused by hydrothermal fluids, there isack of consensus for the roles that nonmagmatic vs. magmatic fluids played.
