Abstract

A method for increasing the yield of a deposit including a rock which including at least one valuable mineral to be exposed by comminuting the rock and at least one further mineral, may include the following steps: performing a boring operation using a boring device prior to extracting the rock, determining at least one predetermined boring parameter for the boring device, determining at least one measured value characterizing a current boring behavior of the boring device, and performing a computational elimination of a dependency of the at least one measured value on the at least one boring parameter, wherein at least one rock texture-dependent characteristic value is obtained, and wherein the at least one characteristic value is used as a measure for a mineral particle size of the at least one valuable mineral in the rock and for setting an optimum degree of comminution when comminuting the rock.
