Comparison Of Oxide And Sulphide Copper Ore Deposits

Copper Oxide Ore Leaching Ability and Cementation Behavior

One of the Iranian copper deposits that is located east of Iran and also known as a primeval one in that area is Mesgaran Field. Old mining works have been clearly seen in the area. Iran is located on global copper belt and as a result it has numerous potential areas as copper deposits. The purpose of this study is identifying possible potentialities of copper mining in less developed regions .

Ore deposits formed by oxidation and supergene enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table or to .

Copper Mining and Extraction Oxide Ores

Copper Mining and Extraction Oxide Ores. Copper is refined from ores in the ground either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 1114 but is introduced here because an .

oxide and sulphide ores

Why are the sulfide ores generally converted to an oxide . Jun 27 2018 The concentrated ore must be converted into a form 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. a conversion to .

EFFECT OF GRINDING CHEMISTRY ON THE

The effect of pulp chemistry on oxidised copper sulphide minerals and copper oxide minerals were first studied separately before examining a mixed system. The work completed on the oxidised sulphide mineral revealed that grinding pulp chemistry affects the flotation performance of the ore for each oxidation degree tested. For the

Why the world is demanding more cobalt and why new

Sep 29 2017 Cobalt is found primarily with mineral deposits of nickel and copper in the Earth. There are many different cobalt ores that are mined involving many steps of separation and purification. The most well-known and mined ores are nickel cobalt sulfide copper cobalt sulfide copper cobalt oxide nickel cobalt laterite and cobalt arsenic ores.

PDF Flotation of mixed copper oxide and sulphide

Copper sulphide ores Flotation collectors From previous otation investigations of mixed copper oxide and sulphide minerals using xanthate and Mineral processing hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sul- Alkyl hydroxamates phide recovery as the sulphide and oxide minerals occurred .

POLYMETALLIC VEIN AND REPLACEMENT DEPOSITS

Deposits consist of massive lenses and or pipes known as mantos or replacement orebodies and veins of iron lead zinc and copper sulfide minerals that are hosted by and replace limestone dolomite or other sedimentary rocks most massive ore contains more than 50 percent sulfide minerals. Sediment-hosted ore commonly is intimately

oxide and sulphide ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 1114 but is introduced here because an important byproduct of this process is used for the extraction of oxide ores.

Magmatic Ore Deposits in Layered

figs. 1 and 2. These deposits are mined primarily for their platinum palladium and rhodium contents table 1. Magmatic ore deposits are derived from accumulations of crystals of metallic oxides or immiscible sulfide or oxide liquids that formed during the cooling and crystallization of magma typically with mafic to ultramafic compositions.

Treatment of Mixed Sulfide Oxide Ores of Copper

Sep 25 2016 Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines with a total copper content of from 1.3 to 2.0 per cent. send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide minerals are considered satisfactory using modern flotation .

Atacamite in the oxide zone of copper deposits in northern

Nov 28 2006 Copper minerals are atacamite and brochantite within the oxide zone and chalcocite covellite and pyrite in the enriched zone. Primary sulfides comprise chalcopyrite bornite molybdenite tennantite and pyrite. Reserves recoverable by open-pit mining are 79 Mt of oxide ore at 1.18 Cu and 231 Mt of sulfide ore at 1.13 Cu.

The Smelting of Sulfide Ores of Copper in Preconquest

With a simple sulfide ore like chalcocite once the sulfur has been burned off as sulfur dioxide SO2 and the copper sulfide thus converted to copper oxide the oxide can be reduced with charcoal described above Thompson 1958 4. How the Indians happened on the roasting of sulfide ores may never be known. Obviously
