An experimental procedure is given for testing additives in a laboratory ball mill. Application of the additives to industrial ball mill and rod mill circuits is discussed. Experience suggests that additive costs of 12 30 c (U.S., 1980) per ton of dry ore are economically justifiable.

2. Experimental Procedures . The experimental procedures used are the batch process using a novel ring mill, a laboratory ball mill, a labora tory rod mill and the semi continuous process using the same rod mill as described below. In all cases the min eral sample is crushed and screened to pass a predeter mined size 3.5 or 4 mm.
