Performance of briquettes as potential feed into the electric arc furnaces at the Barro Alto, Brazil operation

The purpose of this study was to evaluate the performance of briquettes as potential feed into the electric arc furnaces at the Barro Alto operation. The study considered three key parameters in evaluating the performance of briquettes: moisture content (16% and 24%), curing conditions (open and closed), and PSD of the feed to the briquetting process (−6.3 mm and −12.5 mm). This study complements the results of pilot-plant campaign tests undertaken by Anglo American at the Value-In-Use facility in Pretoria, South Africa. Briquette performance was evaluated using ISO tests for TI, AI, RI DI, and RDI, and the Anglo American Value-In-Use in-house standard Linder furnace test, which simulates conditions in a rotary kiln.
