“…Based on the knowledge of soft magnetic properties of spinel ferrites synthesied by various methods (Viart et al, 2000;Sugimoto, 1999;Lakshmi, Kumar, and Thyagarajan, 2016;Zhang et al, 2016), the magnetic ferrite phases (MFe 2 O 4 , where M is Mn, Ni, Cr, Mo, etc.) in crystallized slags can be exploited in the magnetic separation from the bulk nonmagnetic components (Semykina and Seetharaman, 2011;Semykina, 2013;Shatokha et al, 2013;Sharma, Sharma, and Shah, 2014;Menad, Kanari, and Save, 2014;Ma and Houser, 2014;Li et al, 2015;Lakshmi, Kumar, and Thyagarajan, 2016;Zhang et al, 2016;Jiang et al, 2018). In other words, the transformation of nonmagnetic compounds of transition metals in slags to ferrites with high magnetic susceptibilities by controlled solidification and crystallization of molten slags is a promising method to increase the recovery of values from steelmaking slags.…”

Mining is a complex process involving activities that range from exploration through mine development, mineral beneficiation, metal extraction, smelting, refining, reclamation, and remediation (Bian et al., 2012; Ndlovu, Simate, and Matinde, 2017). In the process of extracting the metal values, these activities produce significant amounts of wastes, typically consisting of (1) solid wastes in the form of waste rock, dusts, sludges, and slags, (2) liquid wastes in the form of waste water and effluents, and (3) gaseous emissions. In South Africa, mining and metallurgical wastes constitute one of the biggest challenges to the environment. If not managed properly, the anthropogenic effects of these mining and metal extraction activities can result in irreversible damage to the environment and a hazard to humans. In South Africa, in particular, these types of wastes are usually disposed of in landfills, thereby creating serious environmental and health challenges for communities. Mitigating the effects of such mining, metallurgical, and metal manufacturing processes requires a holistic waste management approach that incorporates reduction in the amount of waste

This research investigates the applicability of an ANN and genetic algorithms for modeling and multiobjective optimization of the thermal conductivity and viscosity of water-based spinel-type MnFe2O4 nanofluid. Levenberg-Marquardt, quasi-Newton, and resilient backpropagation methods are employed to train the ANN. The support vector machine (SVM) method is also presented for comparative purposes. Experimental results demonstrate the efficacy of the developed ANN with the LM-BR training algorithm and the 3-10-10-2 structure for the prediction of the thermophysical properties of nanofluids in terms of the significantly superior accuracy compared to developing the correlation and employing SVM regression. Moreover, the genetic algorithm is implemented to determine the optimal conditions, i.e., maximum thermal conductivity and minimum nanofluid viscosity, based on the developed ANN.

“…Manganese ferrite, MnFe2O4, also belongs to a group of soft magnetic materials (Hc < 10 A/Cm) characterized by high magnetic permeability, low losses, high saturation magnetization (Ms) and relatively high Curie temperature (Vijaya, Sekaran, and Bououdina, 2015). Manganese ferrite is a magnetic ferrite with cubic spinel structure, which has been used in various technological applications (magnetic materials, gas sensor, and absorbent material for hot gas) (Sharma, Sharma, and Shah, 2014). Nanosized manganese ferrite was stated to be a promising material for environmental applications, as adsorbent material for different inorganic and organic pollutants (Stoia, Muntean, and Militaru, 2015).…”

Manganese ferrite nanoparticles were prepared by microwave-sonication assisted hydrothermal route and produced from wastes of Li-ion batteries and pyrite ash. The leaching solution of waste pyrite ash was used for Fe source while, Mn-bearing solution recovered from the recycling process of end life Li-ion batteries was used as Mn source. X-ray diffractometry evidenced that manganese ferrite can be obtained as single crystalline phase.Scanning Electron Microscope images showed that double-pyramid or octahedron particles were formed with the average size of 24.3 nm. This produced MnFe2O4 nanoparticles denoted good sorption capacity towards to As (101±0.5 mg/g at pH 3).
