“…Artificial neural networks (ANN) predicted the compressive strength of humic acid and bentonite-based pellets, establishing the relationship between input variables (binder content, pellet diameter, and weight) and the output response (compressive strength). Integrating pellet technology and machine learning drives limonite pellet advancement, contributing to emission reduction and environmental preservation [12]. Zhang et al used a pelletizing method to enhance the subsequent iron-making process by applying Guisha limonite, with advantages including large reserves and low price [13].…”
