magnetic separation copper slag

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.

Metal recovery - Harsco Metals & Minerals

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.

Modelling and simulation of a copper slag cleaning . - IOPscience

to 50 μm diameter [3]. 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.

Magnets for the recycling industry | Goudsmit Magnets

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.

Slag - Wikipedia

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.
