a "SAG Mill limiting" condition, i.e., harder ore, or a "Ball Mill limiting" condition, i.e., softer ore exists. For example, a ratio of 1:1.5 or up to 1:2 would indicate a trend away from processing harder ore types and an increasing bias toward processing softer ore types, whereas a ratio of 1:1 or higher would indicate a bias
