Copper Smelting Slag Cleaning in an Electric Furnace by …

A novel slag cleaning method to recover copper from molten copper …

To recover copper from copper slag, a novel slag cleaning method was proposed. The thermodynamics and binary phase diagram of FeO–SiO 2 were calculated first. Then, the effects of experimental parameters on the reduction of Fe 3 O 4, recovery of copper, and slag cleaning mechanism were investigated.

Control of Slag and Insoluble Buildup in Ladles, Melting …

A new flux, Redux EF40L, has been developed that controls and minimizes buildup in pouring ladles, melting furnaces, pressure pour furnaces and magnesium treatment vessels with …

Copper Smelting Slag Cleaning in an Electric Furnace by …

Based on the physicochemical reaction of the melt, the process of copper slag cleaning in an electric furnace could be divided into two steps: reduction and settling. In the reduction stage, excessive magnetite is reduced to provide favorable conditions for the settling.

Development of Electric Furnace Slag Cleaning at …

lead, zinc, and tin from slag in an electric furnace could be enhanced with limestone, possibly by the in-situ formation of calcium carbide. The addition of the limestone significantly improved …

Control of Slag and Insoluble Build-up in Melting …

A new flux, Redux EF40L, has been developed that controls and minimizes buildup in pouring ladles, melting furnaces, pressure pour furnaces and magnesium converter vessels without adverse effects on refractory linings. Slag Formation: The formation of slags in the melting of ferrous metals in the foundry is an inevitable process.

Control of Slag and Insoluble Buildup in Ladles, Melting …

A new flux, Redux EF40L, has been developed that controls and minimizes buildup in pouring ladles, melting furnaces, pressure pour furnaces and magnesium treatment vessels with minimal to no adverse effects on refractory linings. Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable.

MECHANISM OF BUILDUP FORMATION IN AN …

The copper slag cleaning in an electric furnace is based on slag reduction and settling of copper matte inclusions. Copper recovery depends on the slag temperature, degree of magnetite reduction and slag residence time. The formation of solid buildup on the furnace hearth leads to the decrease of furnace volume and slag residence time, affecting

Reclamation of Induction Furnace Slag by Separation of …

Induction furnace slag contain metal due to 1) Smelting i.e process in which slag forms a layer above molten metal so that some particles in molten metal stuck to the slag.

Control of Slag and Insoluble Build-up in Melting …

A new flux, Redux EF40L, has been developed that controls and minimizes buildup in pouring ladles, melting furnaces, pressure pour furnaces and magnesium converter vessels without …

Controlling Slag Defects, Insoluble Buildup in …

Newly engineered fluxes can extend the refractory life of coreless induction furnaces by up to 60% and more. Other benefits include increased service life of pouring vessels, and these fluxes can significantly reduce the …

Development of Electric Furnace Slag Cleaning at …

lead, zinc, and tin from slag in an electric furnace could be enhanced with limestone, possibly by the in-situ formation of calcium carbide. The addition of the limestone significantly improved the removal of copper and also permitted a reduction of the coke level from 5% to 2%. This had the effect of diminishing the iron fall from the slag.

Cleaning of a copper matte smelting slag from a water …

Direct reduction of a copper matte smelting slag from a water-jacket furnace was undertaken in this study by utilising the latent heat energy of the molten slag, thus resulting in …

Process of Copper Slag Reduction in an Electric Furnace and …

Key to implementing modifications aimed at improving the copper slag reduction process is a thorough understanding of its kinetics and thermodynamics. Electric resistance …

Process of Copper Slag Reduction in an Electric Furnace and …

Key to implementing modifications aimed at improving the copper slag reduction process is a thorough understanding of its kinetics and thermodynamics. Electric resistance furnaces are used for this process, and for more intensive copper removal, arc resistance furnaces are used.

Controlling Slag Defects, Insoluble Buildup in Melting and Holding Furnaces

Newly engineered fluxes can extend the refractory life of coreless induction furnaces by up to 60% and more. Other benefits include increased service life of pouring vessels, and these fluxes can significantly reduce the incidence of slag and/or dross inclusions.

Cleaning of a copper matte smelting slag from a water-jacket furnace …

Direct reduction of a copper matte smelting slag from a water-jacket furnace was undertaken in this study by utilising the latent heat energy of the molten slag, thus resulting in a 'cleaned' slag by removal of the lead, copper, cobalt and zinc from the dumped slags.
