The carbothermic reduction of copper slag at the different binary basicity CaO/SiO2 was carried out for recovering iron by wet magnetic separation Calcium carbonate is found to be capable of improving the iron recovery as well as increasing the particle size of metallic iron significantly Experimental evidence showed that CaO reacted with SiO2 to form calcium silicate and FeO
The recovery of metal from copper slag is of great signi cance to the resource utilization of copper slag and the Sarfo et al 2017 followed by magnetic separation which can recover
To comprehensively reuse copper ore tailings the recovery of γ Fe 2 O 3 from magnetic roasted slag after sulfur release from copper ore tailings followed by magnetic separation is performed
At present copper production in China mainly comes in a pyrometallurgical process Generally for one ton of copper tons of discarded copper slag is generated and in China the amount of discharging copper slag exceeds 10 million tons per year [] with the accumulated amount of copper slag over the years exceeding 120 million tons [] Iron can reach
A novel technology modified roasting in CO CO2 mixed gas and magnetic separation was presented to recover iron from copper slag The effects of various parameters such as dosage of flux CaO
Pyro metallurgical copper slag CS waste was used as the source material for ultrasound US silica extraction under acidification processes with 26 kHz with HCl HNO3 and H2SO4 at different
Liao Zengli Tang Pu Zhang Bo et al Experimental study on oxidation modification of copper slag at middle low temperature [J] China Nonferrous Metallurgy 2012 2 74 78 Google Scholar Wang Heng Recovery of copper and iron in the converter slag from a copper smelter [J]
Many modification physical separation processes have been developed Fan et al 2015; Guo et al 2016; Li et al 2019 Molten oxidation magnetic separation is a representative technique A certain amount of oxygen rich air is blown into the molten copper slag and the fayalite is oxidized to Fe 3 O this process imposes strict atmospheric
copper grade of 16 11% and copper recovery of 69 90% was achieved The copper grade on tailings was only 0 2% Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag Several researchers have reported that slow cooling of the slag can lead to an improvement in copper recovery because of the
In recent years several studies have been carried out to recover iron from copper slag by hydrometallurgical and pyrometallurgical processes such as chemical leaching bioleaching magnetic
This paper explores methods for recovering and treating copper slag Metal recovery has been a focal point in recent decades but comes with challenges The process consumes significant energy and its low recovery ratio hampers the advancement of recovery technologies making them economically impractical and difficult to implement on an
Efficient recovery of copper from copper smelting slag by gravity separation combined with flotation Subsequently the iron and copper in the roasted CSS could be effectively recovered by the traditional magnetic flotation separation or their combination whereas the zinc and lead were concentrated into the dust which could be further
LIU Hongtu CAO Yijun FAN Guixia Progress in Comprehensive Recovery and Utilization of Copper Smelting Slag[J] Conservation and Utilization of Mineral Resources 2021 41 3 34 42 doi /
The results show that under the proper conditions the copper grade of rougher copper concentrate was increased from % to % iron recovery of magnetic separation was increased
In this study a novel method to recover copper zinc and iron from copper slag by SO 2 O 2 roasting leaching magnetic separation was proposed The effect of roasting experiment conditions were roasting temperature of 900 °C holding time of 120 min and φ SO2 The volume fraction of SO 2 in the mixed gas of SO 2 and O 2 of 90% Under the leaching
Iron grain growth during deep reduction roasting is important for iron enrichment from copper slag CS through magnetic separation In this work a novel method of additive free activation roasting including oxidation and subsequent reduction roasting was proposed to increase the iron grain size then the iron was extracted by magnetic separation
During smelting copper slag is generated in the form of matte and a higher copper content in the slag will give a higher matte grade Even after dilution the copper content in slag can remain
