Ore recovery and ore dilution are very important indicators in almost all mining exploitation methods, and are especially important in the sublevel caving mining method. In the sublevel caving mining method, there is an inverse proportion in the ore recovery and ore dilution, that is, by increasing one parameter the other is reduced, and vice versa. With each increased percent of ore dilution and reduction of ore recovery, there is a negative impact on the economic value of the ore reserves in the deposit, i.e., the content of metal in the ore is reduced, thereby increasing the production costs for treating the ore from loading to the final processing. In this paper will be presented laboratory methods in which the correlation between the coefficients of ore recovery and ore dilution in the sublevel caving mining method can be determined
