The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80% passed through a 3000 micron sieve. Further size reduction was completed in a 1.0 xx1.5m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the ommencement of grinding. Data: S.G. of the ore =3.86.
