Abstract in Portuguese
Neste trabalho, foram determinados os Índices Energéticos Específicos WI (Work Index) de 16 materiais, através do ensaio de moabilidade, em um moinho de bolas circuito fechado. Para cada amostra de material, o ensaio de moabilidade foi realizado em cinco malhas diferentes de peneiras teste, obtendo-se assim, cinco valores distintos de Wi. Finalmente, para as 16 amostras, foi determinado um total de 80 ensaios de moabilidade. Com estes dados, foi possível o estudo da variação do Wi, em função do tamanho das partículas.

Abstract in English
In this work, Work Index Wi of sixteen materials was determined through a moability test, in ball mil closed circuit. For each sample, moability test was done in five diferente screens, resulting in five diferente values of Wi. Finally, eighty moability tests were done for the sixteen samples. With those results, the Wi variation was correlated with the size of particles.
