Method and device for increasing the yield from a mineral deposit

摘要

The method involves executing a drilling process by a drilling device (1) before cutting a rock (10a) such that drill cuttings are produced. Aerosol including the drill cuttings and gas stream is formed. The aerosol is conveyed from the drilling device to an air separator (5). A stream classification process is executed such that fractions (6a-6c) including same particles of the drill cuttings are formed. A property of the fractions used as a measurement for adjusting an optimal breaking degree of the rock is determined. An independent claim is also included for a device for increasing the yield from a mineral deposit.
