Utilization of Waste Copper Slag to Produce Directly Reduced Iron .Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coal-based direct reduction-magnetic separation process was developed to recover iron from the slag assaying 39.85% Fetotal and 0.33%.magnetic separation copper slag,Preparation of metallic iron powder from copper slag by .Copper slag is a solid waste that has to be treated for metals recovery. In order to recover iron from copper slag, the technology of carbothermic reduction and magnetic separation was developed. During the reduction roasting, additive CaO reacted with Fe2SiO4 of copper slag, forming CaO·SiO2 and 2CaO·SiO2, which.

The reductive product was pulver- ized to a particle size with diameter of 0.045 mm. Cu was then separated from iron by means of magnetic separation and recycled by gravity separation process. RESULTS AND DISCUSSION. Composition and Structure of Raw Material. Copper slag was analyzed with optical sheet iden-.
May 25, 2017 . To improve the recovery of copper, the viscosity of copper molten slag is decreased by the reduction of magnetic iron, which, in turn, accelerates the settling and separation of copper droplets from the slag. A new technology is proposed in which waste cooking oil is used as a reductant to reduce magnetic.

In this study, a new technique was proposed for the economical and environmentally friendly recovery of valuable metals from copper smelting slag while simultaneously upgrading nickel laterite through a co-reduction followed by wet magnetic separation process. Copper slag with a high FeO content can decrease the.
Experimental Study on Comprehensive Recovery of Valuable Minerals from Flotation Tailings in Copper-Molybdenum Mine p.234 · Enhanced . Iron recovery from a lead slag in Shanghai province was carried out with the technique of coal-based direct reduction followed by magnetic separation. Scanning electron microscopy.
For carbon steel slags: after screening of slag materials our magnetic separation process ensures the highest level of metal recovery. Through further crushing and screening, the scrap can be upgraded to high-Fe material for use as coolant scrap in the mill. The residual slag is sold as an aggregate. For stainless steel.
to 50 μm diameter . For these small-sized droplets, however, the gravitational settling is too slow for an efficient cleaning process. To increase the separation rate, a magnetic field orthogonal to the electric field is introduced, which generates considerable stirring of the slag. Stirring increases the probability of inter-droplet.
Through various real-world tests Goudsmit has determined that the 38HI technology performs best in the slag-reprocessing sector. This is due to the extremely high magnetic force and rotation speed. Particularly when it comes to the separation of heavy metals such as copper and brass, we achieve a significantly higher.
In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds.
Separation technologies for upgrading scrap include sorting methods based on physical properties, such as magnetic and electrical properties, density, and melting point (see Chapter 10). Copper should be removed from solid steel scrap before it goes into solution. Promising techniques include cryogenic fragmentation of.
