Production Of Copper Matte

Converter Blowing of Matte the pyrometallurgical oxidation processing of molten copper, nickel, and lead mattes to produce a crude metal or a nonferrous metal sulfide. Converter blowing is performed in a converter by blasintg the molten matte with air or industrial oxygen. When the jet of air passes through the melt, mainly the sulfides of metals that

Cement copper is often added to the charge which goes to a converting furnace to produce copper matte. Note Cement copper must not be confused with copper powder, which does not contain impurities. Copper matte and cement copper are covered each by one code of the Harmonised System HS HS 7401.10 Copper mattes HS 7401.20 Cement copper

Lorenen Synopsis The leaching behaviour of nickelcopper matte in an acidiccopper sulphate solution during the repulping stage at Impala Platinum Refineries has been studied. The base metal recovery process consists of a matte repulping stage prior to a series of pressure

2018-6-12In this study, the aim was to reduce copper losses to slag in copper production by using a boron compound, called colemanite 2CaO.3B 2 O 3.5H 2 O, as flux, besides silica. In order to achieve this purpose, two different matteslag couples were used the flash furnace matte-slag obtained from Eti Copper Inc. EB and a master matteslag without copper produced synthetically under

2012-12-5When one considers the copper matte formed in the furnaces mentioned above, the matte liquidus temperatures range from around 940C to around 1125C, and a maximum difference of 360C between the operating temperature and the matte liquidus temperature is observed Figure 1

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2S O2 2Cu SO2 The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2

The lower matte layer, with about 40 to 75 of copper, and containing most of original metal present, is transferred to the converting step to produce blister copper. -- 4 Production of blister copper --During the production of blister copper the matte is converted to blister in a converter by oxidation in two stages

A method of treating a copper foil comprising the steps of providing an electrodeposited copper matte surface on at least one raw surface of said copper foil, and forming an electrodeposited metallic barrier layer comprising 65 to 80 weight copper, 20 to 35 weight inc and 2 to 5 weight antimony on said electrodeposited copper matte surface

Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and lead.Instead of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 4045 percent copper along with iron and sulfur, which is then treated by converting in a Bessemer-type converter

Abstract. Smelting is an important process in copper production to produce matte and slag. The slag, containing about 112 Cu, can be further processed to recover the copper contaminated, but recycle of the slag concentrate reduces overall productivity and efficiency of the operation

Several different processes can be used for copper production. The old traditional process is based on roasting, smelting in reverbatory furnaces or electric furnaces for more complex ores, producing matte and converting for production of blister copper which is further refined to cathode copper

Outokumpu Oy has intensively studied the production of high-grade copper matte in a flash smelting furnace since the 1950s. Blister copper was first produced in the pilot furnace of the Metallurgical Research Centre at Pori in 1969 and the first commercial plant for direct blister production was commenced in 1978 in Poland
