LATEST RESULTS OF THE SLAG CLEANING REACTOR FOR COPPER RECOVERY 199 The slag velocity is similar. The results of CFD modelling (Figure 3 and 4) for a large furnace show very high slag velocities (up to m/s) below the electrode at low magnetic field values ( tesla). The second part of the channel furnace has a
Slag Deepfield Copper Electromagnet Few materials are as damaging to magnets and equipment as slag, but the extreavyduty structural design of the Slag Deepfield Copper Electromagnet (SDC) is built to take it. Whether it''s ultraabrasive scrap, slabs, billets, drop balls, or slag scrap, this is the magnet that can do it all. The copperwound version.

Smelter slag, a byproduct of metallurgical processes, was made and dumped for over 100 years of ore exploitation in Bor Copper Mine. Smelter slag dumps with approximately tons of slag ...
Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper. The rest are iron minerals like magnetic iron ore, metallic iron and gangue like fayalite, hedenbergite and amorphous phase matter. Such slag can be concentrated by separation and enrichment to obtain copper .
Jun 09, 2020· Effects of Na2O Additions to Copper Slag on Iron Recovery and the Generation of Ceramics from the Nonmagnetic Residue Article in Journal of Hazardous Materials 399:122845 · May 2020 with 28 Reads
Aiming at recovering iron from highironcontent copper slag, this article introduced a combination technology of deep reduction and magnetic beneficiation, investigated the iron recovery efficiency and optimized the technical conditions. When coke powder with 86wt% fixed carbon was used as a reductant, iron was successfully extracted from the copper slag. Under the optimized condition of the ...
A new process for green and efficient utilization of copper slag was put forward. • Addition of Na 2 O in slag promoted magnetite growth but decrease magnetite quantity.. Slag with 4 % Na 2 O had a markedly decreased viscosity and iron recovery rate of %.. Na 2 O in ceramics reduced sintering temperature but meantime degraded bending strength.. Nonmagnetic residue containing Na 2 O ...
Iron recovery from copper. In order to recycle iron from copper slag with total iron content(TFe) of 3996%(mass fraction),a technique with lignitebased direct reduction followed by magnetic separation was presentedAfter analysis of chemical composition and crystalline phase,according to experimental mechanism,the tests for studying the effects of different parameters on the recovery of iron ...

A magnetic product containing about % iron was obtained from the magnetic separation under a magnetic field strength of 100 mT. Large amounts of copper slag containing about 40 wt% iron is generated during the process of producing copper. Recovery of iron from the copper slag is very essential not only for recycling the valuable metals ...
Recovery of copper by electrochemical technique from dross scrap of the state Company for Electrical Industries was studied by [9]. After many chemical process he was recovered % Cu from dross scrap with purity %. Hydrometallurgical method to recovery copper, zinc and cobalt, from copper smelter slag in the presence of
copper recovery magnetic slag . copper recovery magnetic slag. We offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals.
Copper sulphide and copper metal (with its inherent cobalt content), because of their higher densities and immiscibility with the slag, settle from the molten slag into the metal bath. Improving recoveries via this mechanism would involve decreasing the viscosity of the slag (by increased temperature or flux additions), and / or increasing the ...
Recovery of cobalt from converter slag of Chambishi Copper ... techniques, such as slag cleaning, slow cooling of the slag followed by milling and flotation, are inappropriate for cobalt recovery from converter slag [7−8]. ... Centrifugal separators ... slowcooled converter matte into a magnetic fraction. .... to first separate PGMs from ...
Metal Recovery from Steelmaking Slag. air oxidation and magnetic separation. The oxidation of slag was carried out in both solid and liquid states, attempting to optimize the conditions of each. The effects of oxidation time, temperature, slag basicity, and magnetic field strength on recovery 3 O. Get Price
The invention relates to a method for reducing and extracting copper smelting waste slag through microwave carbon heating, which comprises the following steps: pulverizing copper slag, reducing agents (one material or a mixture of several materials in anthracitic coal, graphite, refinery coke and coke) and calcium oxide or calcium carbonate; mixing the ingredients; adding binding agents for ...
JOURNAL METRICS. Citre 2019: ℹ Citre: Citre is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.
