DETERMINATION OF GOLD ORE DEPOSITION INDUSTRIAL MINERALISATION BOUNDARIES Russian patent published in 2014 - IPC G01V9/00 

FIELD: mining.

SUBSTANCE: geological sampling is made according to test grid. Samples are prepared by crushing, grinding, reduction, division and taking analytical samples. Gold content is defined in analytical samples. Rich and lean sections of gold ore deposit sections are isolated with allowance for accepted conditions. Industrial mineralisation of gold ore deposit is delineated. Then extra geological samples are taken at lean sections at least three paces from the boundary of rich section. Extra geological samples are prepared. Analytical samples are taken in weight at least twice as heavy as the main analytical sample. Every extra analytical sample is processed in centrifugal field with at centripetal acceleration over 25 units of free fall acceleration to produce concentrates and tails. Gold content is defined in said concentrates and tails to calculate it in terms of appropriate extra sample. Results of said calculations are used to refer said section to industrial mineralisation with refinement of delineation.

EFFECT: higher accuracy of industrial mineralisation delineation.
