This study used iron ore obtained from Muro town, a community in Toto LGA, Nasarawa state as the test ore. Marble and Granite which was separately used as the reference ores were obtained from Muro environs. 100 g each of the test ore and the reference ores were subjected to the same grinding conditions in a ball mill. Size analysis of the feed to the ball mill and the product of the ball mill for both test ore and reference ores were carried out and the results tabulated accordingly. The 80% passing particle size of the ball mill feed and discharge for the samples were calculated using the Gaudian Schumann expression. The Bond’s equation was then used to calculate the work index of the Muro iron ore which was found to be 24.84 kWh/ t when marble was used as reference ore and 27.41 kWh/ t when granite was used as reference ore. The average work index of Muro iron ore was calculated as 26.13 kWh/ t, while the energy requirement for grinding the ore was found to be 3.62 kWh/ t. The value of the work index of Muro iron ore is within the limit of work index of iron ore quoted in literatures","PeriodicalId":177348,"journal":{"name":"Journal of Advanced Research in Manufacturing, Material Science & Metallurgical Engineering","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114647627","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}

Any atomic molecule ranging from 1 to 100 nanometre is known as nanomaterial. This review is about characterisation, synthesis and applications of the nanoparticles. The techniques such as X-ray diffraction, SEM, EDX, TEM, DC Conductivity, PSA and TG/DTA were used for the characterization of nanoparticles characterisation of nanoparticles is necessary for understanding its aspects and applications. In synthesis of nanoparticles we have studied physical and chemical aspects of nanoparticles such as size, shapes and chemical composition. Classification of nanoparticles is also studied in this review. The three dimensional structures of the particles can be studied by using HRTEM, STEM, EELS and EFTEM. The prime application of the nanomaterial is in the field of biomedical for drugs, gene delivery and cancer therapeutics. It is widely used in the display of television and monitors. In food technology it is used for the protection and packaging of food materials. And it has also made the construction materials affordable.","PeriodicalId":177348,"journal":{"name":"Journal of Advanced Research in Manufacturing, Material Science & Metallurgical Engineering","volume":"37 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124965315","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}
