Ten SM were defined based on phase association, phase texture and particle texture. The SCH/SCFT of each microtype was calculated by defining an idealised composition and utilising the mean microhardness/fracture toughness of different textural forms of common sinter phases. Comparison of SCH and SCFT with sinter metallurgical indices and major element chemistry showed relatively stronger linear correlations with the latter. Modifying the idealised compositions of SM to calculate SCH/SCFT did not notably change correlations with sinter RDI, RI, TI. Calculating SCH/SCFT by weighting the input of SM variably improved correlations with sinter RDI, RI, TI. Providing additional weighting to nuclei/primary phase-bearing SM provided the best correlation with RDI and RI, whereas additional weighting to bonding phase-bearing SM provided the best correlation with TI.","PeriodicalId":43710,"journal":{"name":"Mineral Processing and Extractive Metallurgy-Transactions of the Institutions of Mining and Metallurgy","volume":"132 1","pages":"1 - 12"},"PeriodicalIF":1.2,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46397476","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 prerequisite to improve spirals' performance is to understand the forces that affect valuable and gangue minerals' separation. This paper investigates how magnetic properties of particles can be used to achieve a sharper separation of magnetic and non-magnetic particles in spirals. To this end, separation behavior of a synthetic mixed magnetite and quartz particles in the presence and absence of magnetic field was investigated via analyzing variations in the forces that affect particles’ separation in a spiral. Changes in Zero force line were considered as the reference point in the studies. In this regard an innovative magnetic-spiral was designed and fabricated. A magnetic force was added to separation process of the selected spiral. This, increased fine particles grade and recovery up to 8.5% and 7.5% respectively.","PeriodicalId":43710,"journal":{"name":"Mineral Processing and Extractive Metallurgy-Transactions of the Institutions of Mining and Metallurgy","volume":"131 1","pages":"345 - 354"},"PeriodicalIF":1.2,"publicationDate":"2022-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41981055","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 force normally is the resultant of gravity, buoyancy and drag forces. Therefore, the settling velocity of coarse and light particles is very close to that of fine but dense particles. This fact is the major cause of poor beneficiation of fine valuable minerals in gravitational separation devices like spirals. So, implementing of an external force such as magnetic force may well improve the beneficiation of such particles. Theoretical analysis of terminal settling velocity (TSV) of particles shows that a magnetic field aligned with gravity can increase TSV of minerals with magnetic properties which in turn results in higher free settling ratios between magnetic and non-magnetic particles. In this regard, an innovative laboratory device was designed, fabricated and used to better understand the simultaneous effects of gravity and a magnetic force aligned with it.","PeriodicalId":43710,"journal":{"name":"Mineral Processing and Extractive Metallurgy-Transactions of the Institutions of Mining and Metallurgy","volume":"131 1","pages":"320 - 329"},"PeriodicalIF":1.2,"publicationDate":"2022-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47387768","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 method often used is gravity concentration. The technology that makes use of it is a shaking table. This tool works based on the difference in specific gravity and pаrtіcle size in the flowing film concentration which exerts a thrust against the pаrtіcles on the deck. In an effort to meet the needs of practicum and research in the mining engineering department, especially the Sriwijaya University Mineral Processing Laboratory. For this reason, the existing equipment in the laboratory is modified by changing the design and size of its main components. The deck is designed with a length of 170 cm and a width of 102 cm. The riffles are installed parallel to a height of 3 mm, a width of 1 cm and a spacing of 3 cm. Experimentation is carried out by adjusting the variation of the variables. The variables used as parameters are deck slope (4°, 6° and 8°), water flow rate (10, 12 and 15 L / min) and feedingspeed (5, 10 and 15 minutes). The sample used was refined tin ore. Sampling at two locations, namely sample A at the Bantam B122 Collection Station, Belinyu and sample B at the TKT DU1521 Jangkang Washing Plant Station.","PeriodicalId":43710,"journal":{"name":"Mineral Processing and Extractive Metallurgy-Transactions of the Institutions of Mining and Metallurgy","volume":"48 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79059575","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}
