Recycling Nickel Slag by Aluminum Dross: Ironextraction ...
Nickel slag is a metallurgical solid waste from nickel refineries, which can be recycled as one of excellent secondary sources due to valuable iron contents. In this work, the approach of recycling nickel slag by aluminum dross was proposed, and the processes of network modifiion of slags and reduction were successively investigated at 1773 K. Upon the thermodynamic calculations, CaO was ...
Slag | Some Meteorite Information | Washington University ...
Slag usually refers to a glassy byproduct of smelting ores to retrieve the metal. I use the term here to also include any manmade, rocklike byproduct of heating things to high temperature. Thus, clinkers are a form of slag. Slags ch people attention because of their morphology. Many slags contain metal from inefficient separation of ...
Optimized Slag Design for Maximum Metal Recovery during ...
alloy at 1400°C, which is further converted to remove the iron content. The MnO, FeO containing slag is further reduced to produce ferromanganese. The converter slag may be used to adjust the FeO/MnO ratio in this step. Thus, creating a nearly zerowaste process, if the produced slags are suitable for further use. More than 95% of the nickel, copper and cobalt are reduced into this metal ...

The experiments were carried out employing a dropquenching technique followed by direct spot analysis with electron microprobe and laser ablation inductively coupled plasma mass spectrometer [29] to quantify the phase ...
Solubility of nickel in slags equilibrated with NiS melt ...
The nickel content in the slag and the sulfur content in the metal at given pO2 and pS2 were smallest for the CaOAl2O3 based slag. Both decreased with increasing temperature. At 1873 K, the content of nickel in the CaOAl2O3 based slag at pO2 of 10 Pa (near the precipitation of NiO) was 4%, while the content of sulfur in alloy is mass %. Thus, the CaOAl2O3 base slag at 1873 K would be ...
Unlocking millions of tonnes of nickel
In collaboration with the Sydneybased SME Direct Nickel, we are testing a new extraction process that could make millions of tonnes of untapped nickel laterite reserves economically viable. Direct Nickel has developed a more costeffective and efficient way to extract nickel .
PAPER OPEN ACCESS Effect of nickel slag as a sand ...
· about 80% iron and 20% nickel was generated, and also the slag. In Indonesia, about 4 million tons of nickel slag is produced annually and only utilized for landfilling. Nickel slag contains harmful elements such as Pb, Zn, As, Cd, Co, and Cu, [3] which cause hazards for human health. A possible breakthrough for both environmental problems can thus be sought in exploiting nickel slag .

Previously, an ironbased, slagfree, selfshielded metalcored wire showing a mechanism of porosity prevention was reported in the Welding Journal (Ref. 1). In this paper, a type of ironbased, slagfree, selfshielded metalcored wire with various nickel contents was developed to fabrie experimental hardfacing alloys. The influence of nickel addition on the microstructure and wear ...
Pyrometallurgical process for smelting nickel and nickel ...
These calculations indie that CO is the predominant gas product to extract nickel out from slag or to reach the ironsaturation point of slag. It is assumed in the calculation that there is no solid carbon in the system (which in fact there would be to reduce CO 2 to CO). The energy required for the carbothermic reduction of slag is a function of CO 2 produced. The primary criterion ...
Meteorites and Craters
· Lumps of iron slag from smelting processes can also have some similarities to meteorites. The major difference between iron produced by human activity and meteoritic iron is the presence of the element nickel. Iron metal in all meteorites contains at least some nickel whereas manmade metal objects generally do not. In addition, the interior structure of iron meteorites is unique and unlike ...
Production of FeNi from high iron nickel ores
iron and nickel oxides took place. The furnace operation was fairly smooth, but slag boil did occur mainly due to incomplete calcination of the ore in the rotary kiln'. As time went by and the process was adopted in more plants, more experience with different ores and reductants was obtained both in commercial and pilot plant operation. Several improvements in the RKEF process concept were ...
Trace Metals Related to Historical Iron Smelting at ...
manganese, iron, nickel, and zinc were concentrated in slag. Soil was sampled at eight loions. Seven sites were near the furnace, and one site about mile away from the furnace was sampled for comparison (background conditions). The soil near the furnace had elevated concentrations of chromium, copper, iron, lead, and zinc compared to the background soil samples. However, the ...
Ferroalloy
Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the ...
The Effect of Activators on the Mechanical Properties and ...
· From this list, nickel slag, which is the subject of discussion in this article, is industrially discharged during the production of nickeliron alloy. Indeed, the rapid growth of the industry and the continuous improvement of industrialization levels in developing countries such as China have led to a rising demand for nickel.
Weldability of Materials
Flux cored wires, nickeliron and nickelironmanganese wires, are also available for welding cast irons. Powders are based on nickel with additions of iron, chromium and cobalt to give a range of hardnesses. Weld imperfections. The potential problem of high carbon weld metal deposits is avoided by using a nickel or nickel alloy consumable which produces finely divided graphite, lower porosity ...
