process is feasible to recovery iron because good separating and recovering indexes are obtained. grinding - stage magnetic separation, an
this invention particularly relates to a process for recovery of iron from a waste like granulated copper slag generated during the production of copper this invention particularly relates to a process for recovery of iron from a waste like granulated copper slag generated during the production of copper
yang [17] studied the direct reduction process with lignite-based direct reduction followed by magnetic separation. when mass ratio of copper slag/lignite/cao
the experimental results show that under the treatment condition in this work about 70 of the iron was recovered from the waste slag, where the iron content in
processing of red mud to obtain sintered iron ore was developed by krupp. addition to the metallic fraction a slag that is easily
the recovery of major components of bauxite residue by carbothermic reduction at 15501750 c and subsequent slag leaching in a na3co3(aq)
amorphous material [5]. the processing technologies are different depending on the. metals to be recovered from copper slag. magnetic separation. and reduction
this study was intended to recover pig iron from the copper smelting slag by smelting and refining process, and about 1.5 million tons of copper slag
due to the large content of basic oxides in steel slags, such recycling process saves considerable amounts of iron ore, limestone and dolomite. it has been
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
steel slag these mills grind the slag and recover iron content in it through magnetic separation udc 669 054 82 669 184 244 66 processing and the ironsteel
request pdf recovery of titanium from blast furnace slag 53 of the ti is carried through processing into iron-rich concentrations for
the reduction kinetics determines the efficiency and energy consumption of the reduction process and the direct reduction of iron (dri) product quality. in this
extraction of manganese and iron from silicon steel slag as function of reduction furnace to recover the metal and flux values, but recycling.
by using dr followed by a magnetic separation process for iron recovery from copper slag, yang [10] obtained iron powder of 92.05 iron content
since the copper smelting slag contains high content of fe, cu and valuable metals, interest in recycling it is increasing. the high fe content in the copper
steelmaking slags are usually processed for iron recovery by dry magnetic separation. the recovered iron-rich products are recycled back into the ironmaking
in comparison, the direct reduction process may be the best process for recovering iron from copper slag considering the efficiency, cost,
3.1 the wet steel slag treatment process adopted by our factory can not only recover steel particles in steel slag but also recover iron
in this process, the high viscosity and melting point limit the growth and aggregation of iron oxides, making magnetic separation difficult (li et al. 2013;cao
j. palacios and m. snchez, wastes as resources: update on recovery of valuable metals from copper slags, miner. process. extr. metall., 120(
blast furnace slag (bfs) is a non-metallic (oxidic) byproduct, resulting from the process of obtaining cast iron in furnaces, where the melting of iron
the recovery of iron and other metals from the eaf slag using smelt-reduction process was studied with coal as the reductant.1 division of mineral processing, lule university of technology, except for blast furnace slag and they are actually a secondary resource of metals.
the combination of low and high intensity magnetic separation (lims and hims) of ground ld slag at 63 m in wet process may recover
