Material degradation through corrosion is sure to happen quickly and slowly. This study aims to determine the most significant factor causing corrosion and the types of corrosion in the filter feed pump installed in the wastewater treatment plant. Identification of failures is made by conducting visual inspections and literature studies regarding the plant operation, inspection, repair, and replacement data. From these data, an analysis of the aggressiveness of fresh water, an analysis of the operation and maintenance of the causes of corrosion failure on pump components, and the type of corrosion that occurred on pump components are carried out. In addition, analyses are also carried out regarding the possible combination of causes of corrosion failure between redox reactions and loading, which causes stress corrosion cracking and fatigue corrosion. Based on the studies, it was found that the operation, maintenance, and environmental factors cause the corrosion that occurs. Lack of maintenance is the most dominant fault as factor causing corrosion. Not doing predictive maintenance causes tremendous damage to the pump casing cover. The oxygen difference factor also causes failure of the casing, wear ring eye, bearing bracket, and shaft. The results of identifying the types of corrosion that occur in the filter feed pump components include uniform corrosion, pitting corrosion, crevice corrosion, stress corrosion cracking (SCC), fatigue corrosion, erosion-corrosion, and cavitation corrosion.","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115289481","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}

The dominant chromite ore mined is utilized for the manufacture of ferrochrome, the rest for refractories and paint materials. The Palludda Barru area contains chromite ore with low grade or cannot be utilized further. A suitable concentration method for processing chromite ore is the gravity concentration method, one of which is a shaking table. The research was conducted with the aim to determine the amount of increase in grade and recovery of chromite ore from Palludda Barru using shaking table gravity concentration. Samples from the Palludda Barru field were first characterized to determine the minerals and the levels of minerals or elements contained in the chromite ore. The ore before being fed, was reduced in size using a jaw crusher and ball mill. Experiments were conducted by varying the table inclination angle from 5° to 15°. The results showed that the inclination angle affected the Cr content and recovery obtained. The optimum tilt angle was obtained at 10° with a grade of 35.89% and a recovery of 59.06%.","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115738554","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}

This has an indirect impact on the increase in metallurgical waste resulting from the processing of these materials. In Indonesia, metal processing slag , including Nickel Pig Iron (NPI) slag , is a waste that has yet to be used optimally. On the other hand, NPI slag contains elements such as Pb, Zn, As, Cd, and Co, which have the potential to pollute the environment and harm humans. Therefore, it is necessary to utilize NPI slag as a more valuable product to increase the economic value of metallurgical waste and minimize environmental pollution. In this paper, studied characterization of NPI slag has the potential to be developed as a geopolymer. The characterization was carried out by EDS mapping and XRD on slag NPI with a size of 200 mesh. The characterization results show that there are phases of quartz, clinoenstatite, sillimanite, calcium peroxide, olivine, forsterite, fayalite, and hypothetical silica. The phase was identified through the peaks of the XRD diffractogram at an angle of 20-70. In addition, the mapping results indicate that several compounds, such as silica, magnesium, and oxygen, are","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125339885","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 the study entitled \"The Effect of Low Hydrogen Electrode Drying on Longitudinal Weld Penstock Steel SM 400 B Material Against Welding Defects With Non-Destructive Inspection Test Radiographic Methods\" was carried out to determine the comparison of the welding results of the penstock components using the condition of the electrodes being dried and without being drying and its effect on welding defects produced by inspection of the non-destructive test radiography. The first method of testing is to search for supporting literature, collect field data, carry out radiographic testing, film reading and interpretation of defects. The parent metal used is SM 400 B steel which has been Mill Test certified and has perfect weldability. The welding process is carried out using the SMAW method using the E7016 electrode. Based on research that has been done, the welding defect identified is the Wormhole Porosity cluster.
