Abstract

This study investigates the correlation between electronic waste recycling, material recovery, and the consequent purity levels. It underscores the substantial influence of hydrometallurgical processes on the recycling process. Experiment 2, with an optimum chemical concentration, exhibited a 50% increase in metal recovery efficiency relative to Experiment 1. This illustrates the substantial improvement in material purity attained by hydrometallurgical experiments. The analysis of contaminant removal demonstrates a 40% enhancement in separation efficiency in Experiment 2, signifying the process’s efficacy. Experiment 3, which included further optimization of chemical parameters and modifications to process temperature, achieved a 30% decrease in recycling time, underscoring enhanced operational efficiency. Notwithstanding the elevated beginning expenses of chemical reagents, Experiment 2 achieved a 20% decrease in total recycling costs, underscoring the economic feasibility of the method. This highlights the need of meticulously controlling electronic trash to get elevated material recovery rates and cost-effectiveness. The findings elucidate the interplay between hydrometallurgical methods and electronic waste recycling, presenting ideas for enhancing recycling efficiency and environmental sustainability.
