The state of Para is one the greatest producers mineral substances in Brazil. Kaolin for paper coating industry and bauxite alumina aluminium production are amongst most important commodities. latter responsible generation red mud, a well-known residue from Bayer process. kaolin processing plants also large amounts wastes, this case, very fine-grained kaolinite (white mud). research aimed to fi...

Adsorption kinetics for removal of arsenic was carried out by red mud and its mixtures with haematite, china clay and fly ash besides china clay-fly ash at: adsorbate conc., 5.0 mg1; particle size of adsorbent, <53 μm; agitation rate, 220 rpm; pH, 8.0; and temp., 30, 40 & 50°C. Data fit into Lagergren equation and adsorption follows first order reaction kinetics. As(III) removal by adsorbents i...

polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. in this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. polyanionic cellulose nanoparticles are made by using of ball milling. size of nanoparticles is measured by particle size analyzer. polyani...

Red mud is a potential iron resource that needs to be urgently exploited and utilized. However, due the properties of high alkalinity, fine particle size complex mineral composition, utilization red difficult. Focusing on mud’s prominent feature this paper studies influence NaOH content reduction kinetics hematite, which main component mud. The results show conversion degree hematite was strong...
