We do not add steel balls to the mill, thus the grind is too coarse. I am responsible for the metallurgical plant. The people above me just wants "tons"! I know what to do! I would reduce tonnage to assist the mill with grinding in order to improve the grind. It is a gold plant. You require 80% -75um. The grind is currently at 40-45% -75um.
