Advanced simulation of removing chromium from a synthetic wastewater by rhamnolipidic bioflotation using hybrid neural networks with metaheuristic algorithms
Khoshdast, Hamid; Gholami, Alireza; Hassanzadeh, Ahmad; Niedoba, Tomasz; Surowiak, Agnieszka (Peer reviewed; Journal article, 2021)This work aims at presenting an advanced simulation approach for a novel rhamnolipidic-based bioflotation process to remove chromium from wastewater. For this purpose, the significance of key influential operating variables ... -
Evaluation of the Effects of Coal Jigging by Means of Kruskal–Wallis and Friedman Tests
Niedoba, Tomasz; Surowiak, Agnieszka; Hassanzadeh, Ahmad; Khoshdast, Hamid (Peer reviewed; Journal article, 2023)Coal beneficiation processes are often based on gravitational enrichment techniques. Therefore, various types of jigs are often used in this area. A number of factors determine the quality of the final product. Therefore, ... -
An Evaluation on the Impact of Ore Fragmented by Blasting on Mining Performance
Nikkhah, Ayyub; Vakylabad, Ali Behrad; Hassanzadeh, Ahmad; Niedoba, Tomasz; Surowiak, Agnieszka (Peer reviewed; Journal article, 2022)In open-pit mines, the blast operation should be effectively optimized, leading to minimization of production costs through the application of specific technical specifications. However, there is inadequate information in ... -
Optimization of Coal Production Based on the Modeling of the Jig Operation
Surowiak, Agnieszka; Niedoba, Tomasz; Wahman, Mustapha; Hassanzadeh, Ahmad (Peer reviewed; Journal article, 2023)This paper presents the jig operating properties of the selected final parameters of the hard coal concentrate. The quality parameters of the product, such as the yield and ash content, were evaluated in terms of the ...
