The effectiveness of using different beneficiation techniques of low-grade iron ore deposits of Assen iron ore mine in Thabazimbi, South Africa has been investigated. The sample received was confirmed to be low grade haematitic iron ore containing (39.18% Fe and 40.29% Si) both lumps and fines. The most abundant gangue present was silica. The different beneficiation methods such as shaking table, drum magnetic separation and reverse flotation were compared on the basis of which one yields a better grade that can b...

In this study, the Springbok coalfields coal samples were collected and subjected to different temperatures ranging between 700-900 пїЅC under nitrogen atmosphere in order to investigate the effect of combustion on the mineral changes. The proximate analysis, calorific value of both raw samples and combusted were carried out. Characterisation and mineralogy of samples (1426, 1427, 1428 and 1429) carried out by X-ray diffraction, X-ray fluorescence, FTIR and SEM incorporated with EDS. Calorific value (CV) ranging f...

Conductive polymer composites due to their unique properties and potential in various applications including chemical and bio sensors are receiving much research attention in recent times. The study investigate the effect of increasing polymer concentration and the influence of mixing time on morphology and electrical conductivity were. A highly conducting nanofiller and reduced graphene oxide (RGO) was incorporated into the matrix of expanded polystyrene; a recycled polymer, and the solution was electrospun under...
