The aim of AJERD is to promote the discovery, advancement and dissemination of innovative and novel original research and development results in different branches of engineering to the wider public. AJERD provides a platform for fast publication of research and development outputs. Apart from the journal-level digital object identifier (DOI) <a title="journal identifier" href="https://doi.org/10.53982/ajerd">https://doi.org/10.53982/ajerd</a>, all papers which are freely available online have individual permanent web identifier. The abstracts will be submitted for indexing in major academic databases. The journal accepts original research contributions that have not been published or submitted for publication elsewhere. Due to the large number of submissions coming in, our publications are now scheduled to three (3) issues with effect from 2025 (Volume 8).</p> <p>Issue 1 (1^st January to 30^th April)</p> <p>Issue 2 (1^st May to 31^st August)</p> <p>Issue 3 (1^st September to 31^st December)</p> <p> </p> <h4><strong>AJERD is indexed by</strong></h4> <h4><strong> </strong> <a title="African Journals Online" href="https://www.ajol.info/index.php/abuadjerd"> <img style="width: 25%; height: auto;" src="https://journals.abuad.edu.ng/templates/images/ajol.png" alt="#" /></a> <a title="Directory of Open Access Journals" href="https://doaj.org/toc/2645-2685"> <img style="width: 15%; height: auto;" src="https://journals.abuad.edu.ng/templates/images/doaj.png" alt="#" /></a> <a title="Google Scholar" href="https://scholar.google.com/"> <img style="width: 15%; height: auto;" src="https://journals.abuad.edu.ng/templates/images/scholar.png" alt="#" /> <img src="http://jsdlp.ogeesinstitute.edu.ng/public/site/images/superjsdogees/ebsco.jpg" /></a></h4> <table style="text-align: center; width: 100%;"> <tbody> <tr> <th> <h4 style="color: green;">4 days</h4> Time to first <br />decision</th> <th> <h4 style="color: green;">28 days</h4> Review time</th> <th> <h4 style="color: green;">63 days</h4> Submission <br />to acceptance</th> <th> <h4 style="color: green;">2 days</h4> Acceptance <br />to publication</th> <th> <h4 style="color: green;">49%</h4> Acceptance <br />rate</th> </tr> </tbody> </table> <p> </p> College of Engineering, Afe Babalola University, Ado-Ekiti, Nigeria en-US ABUAD Journal of Engineering Research and Development (AJERD) 2756-6811 https://www.journals.abuad.edu.ng/index.php/ajerd/article/view/1588 <p><em>The global demand for manganese continues to rise due to its critical role in steelmaking and emerging battery technologies. This study investigates the physicochemical properties and comminution energy requirements of manganese ore from the Anka deposit in Zamfara State, Nigeria. A comprehensive characterization was conducted using Energy Dispersive X-Ray Fluorescence (ED-XRFS), X-Ray Diffraction (XRD), and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS). Particle size analysis was carried out on the as-received sample, followed by a grindability test. The chemical analysis confirmed a high MnO content (52.112%), while mineralogical assessments identified pyrolusite and jacobsite as dominant phases. SEM-EDS analysis revealed the interlocking nature of manganese, iron, silicon, and aluminium within the ore matrix. Particle size analysis identified the optimal liberation size at -125+90 µm, assaying 53.973% MnO. Grindability tests using quartz and iron as reference ores yielded work index values of 11.34 kWh/ton and 14.62 kWh/ton, respectively. The average energy expended during grinding was 5.06 kWh. These findings provide a basis for designing energy-efficient beneficiation processes for Anka manganese ore, contributing to sustainable resource utilization and industrial cost reduction.</em></p> Yemisi Elizabeth Gbadamosi Oladunni Oyelola Alabi Joseph Olatunde Borode Fatai Olufemi Aramide Copyright (c) 2025 Yemisi Elizabeth Gbadamosi, Oladunni Oyelola Alabi, Joseph Olatunde Borode, Fatai Olufemi Aramide https://creativecommons.org/licenses/by-nc-sa/4.0 2025-09-09 2025-09-09 8 3 10.53982/ajerd.2025.0803.01-j
