concentrate, various mining operations have initiated the recovery of copper from dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag.
Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
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 0.08 m/s) below the electrode at low magnetic field values (0.01 tesla). The second part of the channel furnace has a

smelter slag flotation with leaching of copper from flotation tailing. 4.3. Magnetic concentration Suitable granulation of smelter slag residue after flotation and leaching, as well as dominant content of ferrosilicate component, were referring to possibility of utilizing magnetic concentration for recovery of magnetic minerals. Magnetic
The target of the current work is to investigate the possibility of nickel recovery from EAF slag by magnetic separation. To meet the target, the effect of the following parameters was studied: grain size, magnetic field intensity, thickness of slag layer, moisture content, and re-grinding of the coarser slag .
Nov 20, 2013· Abstract. Aiming at recovering iron from high-iron-content copper slag, this article introduced a combination technology of deep reduction and magnetic beneficiation, investigated the iron recovery efficiency and optimized the technical conditions.
Improving Copper Recovery from Production Slags by Advances Stirring Methods Proceedings of EMC 2011 3 treated in the existing copper extraction route or separately in a subsequent reactor the slag phase can be used as construction material for example. 1.2 Conventional pyrometallurgical copper slag .
Abstract 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 and mineral resources but also for protecting the environment.
Apr 01, 2019· An innovative technology for direct reduction-magnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying 40.33% Fe total and 0.65% Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.
Recovery of copper from copper slag and copper slag flotation tailings 77by oxidative leaching Leaching with ferric sulphate The slag and the slag flotation tailings were leached with ferric sulphate in 1 M sulphuric acid. The ferric iron concentration was varied in the range from 5 g/dm3 to
materials from copper slag. Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research. Metals, commercial compounds, alloys and different forms of iron oxides for steel industry are proposed products.
Iron Recovery from Discarded Copper Slag in a RHF Direct ... By using DR followed by a magnetic separation process for iron recovery from copper slag, Yang obtained iron powder of 92.05% iron content with an iron recovery rate of 81.01%, and Wang obtained iron powder of 92.96% iron content with an iron recovery rate of 93.49%.
contain copper with the content ranging between 0.8 to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery of copper. This work focuses on optimizing
copper slag recovery through a flotation route. Almost in all of the flotation methods used to recover copper from slags, the Cu recovery was associated with many problems such as high grade of copper in tailing. In the present study, the use of grinding time increased the copper slag recovery a lot.
