Abstract
THIS WORK IS BASED ON A TECHNICAL AND STATISTICAL STUDY AIMED AT OPTIMIZING NIOBIUM RECOVERY FROM THE ALUMINOTHERMIC STAGE AT CMOC BRASIL, THE SECOND LARGEST PRODUCER OF FERRONIOBIUM ALLOY IN THE WORLD. THE STUDY PRESENTS HOW THE EXCESS ALUMINUM INDICATOR WAS CREATED, AND ITS IMPORTANCE WITHIN ALUMINOTHERMY IN THE SEARCH FOR MAXIMIZING NIOBIUM RECOVERY. AS EXCESS ALUMINUM IS INCREASED, RECOVERY IS ALSO INCREASED. AT THE END OF THE WORK, AN ANNUAL PRODUCTION GAIN OF MORE THAN 320 TONS OF NIOBIUM AND A REDUCTION IN ALUMINUM CONSUMPTION OF MORE THAN 520 TONS PER YEAR ARE PRESENTED, RESULTING IN A FINANCIAL PROFIT FOR THE COMPANY OF 280 MILLION REAIS IN ALMOST 4 YEARS.
