RAZZELL AND TRUSSELL much copper was leached frorn particles of less than 32 mesh in 7 days as from particles of 70 to 140 mesh in 58 days. Although industrial leaching usually would not be conducted on finely ground ore, finely ground material was found advantageous in accelerating laboratory ex- periments. The percentage of copper leached was independent of the quanitity of mineral in the
