Abstract
Official abstract text for this publication.
A method is provided for increasing the yield in a deposit comprising a rock that includes a valuable mineral, which can be exposed by virtue of the rock being comminuted, and at least one further mineral, wherein the valuable mineral has a higher density than the at least one further mineral, which method includes: carrying out a drilling operation using a drilling tool prior to the rock being extracted, drillings being generated in the process; forming an aerosol comprising the drillings and a gas stream; transferring the aerosol from the drilling tool to at least one air separator; carrying out hydraulic classification, wherein at least two fractions comprising in each case equal-falling particles of the drillings are formed; and determining a property which belongs to at least one of the fractions and is used as a measure for setting an optimum degree of comminution of the rock.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for increasing the yield in a deposit comprising a rock which comprises a valuable mineral to be exposed by a comminution of the rock, and at least one further mineral, wherein the valuable mineral has a higher density than the at least one further mineral, the method comprising: performing a drilling operation using a drilling tool prior to an extraction of the rock, wherein the drilling operation generates drillings, forming an aerosol com…
