Selective bio-flocculation of hematite mineral using Bacillus subtilis for phosphorous removal from iron ores [PDF]

open access: yesReciklaža i Održivi Razvoj
Bacillus subtilis is used as a bio-surface modifier to flocculate hematite mineral (Fe 2O 3). The effect of bacterial interaction on the behavior of hematite and apatite minerals, as the main source of phosphorous in iron ore, was investigated using zeta-

Selective flocculation and floc-flotation of iron bearing mineral slimes

open access: yesResearch, Society and Development, 2022
The mineral processing of friable iron ores usually generates ultrafine (smaller than 15 µm) particles, normally called slimes, which usually have a high iron grade and are usually disposed into tailings dam. The traditional mineral process techniques for iron ore do not work efficiently with ultrafines; however, selective flocculation is an ...

Advanced Investigation of the Elimination of Methylene Blue From Wastewater Using Activated Carbon–Copper Oxide Nanowires: New Perspectives With Statistical Physical Modeling

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Shear-Dependent Yield Stress of Iron Ore Fine Tailings in Two-Step Flocculation Process

open access: yesAdvances in Materials Science and Engineering, 2020
Both shear and flocculation have a significant influence on the rheological behavior of tailings, especially the yield stress. In the two-step flocculation process, the above two kinds of actions exist at the same time, and they influence each other.
