In 2021, approximately 1.95 billion metric tons of crude steel were produced globally, compared to 2.6 billion metric tons of usable iron ore. Iron ore is the primary source of the iron and steel industries, which in turn are essential to maintaining a strong industrial and economic base. Globally, 86% of the total iron produced is used in steelmaking. The most important iron ore minerals include hematite, magnetite, and taconite. The other iron ore minerals include goethite, laterite, etc. Hematite and magnetite are most commonly exploited for their iron values. Considering the non-renewable nature of iron ore, there is a paradigm shift towards the upgrading and beneficiation of low-grade iron ore. The widely accepted techniques for beneficiation include jigging, magnetic separation, enhanced gravity separation, froth flotation, etc. Owing to density contrast, iron can be separated from the gangue in simple jigging cycles. The electromagnetic laboratory-scale Wet High Intensity Magnetic Separator (WHIMS) removes fine magnetics and para-magnetics from mineral slurries. The physical and chemical properties of the ore mineral, as well as their mutual relationship, have a large impact on the beneficiation efficiency. In most of the processing units, the small, dense particles report to the tailing fraction, causing a significant loss in ore values. In such challenging cases, the enhanced gravity technique is useful. It is a combination of centrifugal force and gravitational force that facilitates the separation of low-density ore minerals and gangue. The paper focuses on the importance of a characterization study for the success of beneficiation.","PeriodicalId":441295,"journal":{"name":"i-manager's Journal on Material Science","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133355016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, an attempt is made with copper Metal Matrix Composites (MMC) reinforced with an equal proportion of Silicon Carbide (SiC) and graphite powders. The powders are taken in such a way that the reinforcement weight percentage varies from 0 to 10%. The materials are fabricated through the powder metallurgy route. The powder mixtures are blended and then compacted with a uniaxial pressure of 500 MPa to make the green compacted composites with different compositions. The dimensions of all samples are 25 mm x 16 mm x 16 mm, with an average weight of 40 g. Compacted green samples are sintered by the inert gas sintering process. Sintering is performed at 8000C in an inert argon gas furnace for 120 minutes for all the samples. The obtained samples are made suitable for different tests like porosity, the Vickers hardness test, the wear test, Raman spectroscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-Ray (EDX) Analysis. From the values obtained from the hardness test, it is observed that for all MMCs, the minimum value is obtained at Cu-4% (SiC+Gr) and the maximum value at Cu-8% (SiC+Gr), and in between these percentages of composition, there is a little bit of an increase and decrease in values. Wear test results give the maximum wear rate at Cu-4% (SiC+Gr) and the minimum wear rate at Cu-8% (SiC+Gr). Raman spectroscopy test results are given the calculations of Full Width at Half Maximum (FWHM), depth of incident, absorbance, and Id/Ig values, and they are better at 8% of SiC+Gr, which gives the indication of good bonding between molecules of the powder particles. Image analysis is performed using optical microscopy, SEM, and EDX. The microstructures were revealed in such a way that there was good correlation between the properties at different compositions.","PeriodicalId":441295,"journal":{"name":"i-manager's Journal on Material Science","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133955217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
