Abstract

"PELOTAS DE MINéRIO DE FERRO FABRICADAS A PARTIR DE CONCENTRADO COM ALTO TEOR DE GOETHITA E PROCESSO DE PRODUçãO DA MESMA". As pelotas de minério de ferro são produzidas por processo no qual o concentrado de minério de ferro é misturado com os aglomerantes e fundentes, sendo, a seguir, pelotizado em disco rotativos; os elementos resultantes são pelotas formadas que são transportadas para um forno de grelha móvel, onde passam por um processo de queima. A utilização de concentrados de minério temperaturas acima de 200 <198>C com tempo de residência de 3 a 30 minutos para promover a quebra e a geração de novas superfícies antes da mistura com aglomerantes e fundentes."IRON ORE PELLETS MANUFACTURED FROM CONCENTRATE WITH HIGH GOETHITE CONTENT AND SAME PRODUCTION PROCESS". Iron ore pellets are produced by a process in which iron ore concentrate is mixed with binders and fluxes, and is then pelletized in rotating discs; The resulting elements are formed pellets which are transported to a movable grate furnace where they undergo a firing process. The use of ore concentrates at temperatures above 200 ° C with residence time of 3 to 30 minutes to promote breakage and generation of new surfaces prior to mixing with binders and fluxes.
