Resumo

SUSTAINABILITY AND THE IMPORTANCE OF ADDRESSING INDUSTRIAL PROCESSES ARE DIRECTLY LINKED TO THE AVAILABILITY OF NATURAL RESOURCES AND EFFICIENT METAL RECOVERY RATES. IN THE CASE OF BATTERIES, AROUND 90-95% OF THE RECYCLED MATERIAL IS USED IN THE MANUFACTURE OF NEW BATTERIES, WHICH MAKES IT IMPORTANT TO RECYCLE THEM IN ORDER TO REDUCE RISKS AND ENVIRONMENTAL POLLUTION. THE MOST TRADITIONALLY USED PYROMETALLURGICAL PROCESS IS CHARACTERIZED BY THE USE OF HIGH TEMPERATURES TO CARRY OUT THE MATERIAL TRANSFORMATION REACTIONS AND, DESPITE BEING ASSOCIATED WITH HIGH ENERGY CONSUMPTION, IT IS HIGHLY EFFICIENT IN TERMS OF LEAD METAL RECOVERY. HOWEVER, IN THE CONTEXT OF EXTRACTIVE METALLURGY AND APPLIED TO SECONDARY PROCESSES, HYDROMETALLURGY IS APPLIED TO THE RECOVERY OF METALLIC LEAD, HAS BEEN STUDIED AND ACTS BETWEEN THE INTERFACE OF A SOLID PHASE AND A LIQUID PHASE, WHICH INITIALLY INVOLVES A SERIES OF OPERATIONS, INCLUDING LEACHING, SOLVENT EXTRACTION, PRECIPITATION AND BIOHYDROMETALLURGY. THEREFORE, THIS WORK INVESTIGATES THE SECONDARY PROCESSES OF LEAD RECOVERY FROM LEAD-ACID BATTERIES. THE RESULTS SHOW THE IMPORTANCE OF UNDERSTANDING AND EVALUATING LEAD RECOVERY PROCESSES, THUS CONTRIBUTING DIRECTLY TO HIGH EFFICIENCY IN BOTH ENERGY EFFICIENCY AND METALLIC LEAD RECOVERY, WHICH IS DIRECTLY LINKED TO THE ENVIRONMENTAL SUSTAINABILITY OF THE PROCESSES.
