LITHOCHEMICAL METHOD OF MINERAL RESOURCES DEPOSITS EXPLORATION ACTIVITY Russian patent published in 2005 - IPC

FIELD: mineralogogeochemical methods of mineral resources deposits exploration activity.

SUBSTANCE: the invention is dealt with the mineralogogeochemical methods of mineral resources deposits exploration activity and is intended for detection of sulphidic mineralization. The method provides, that on a terrain in compliance with the given network from a representative horizon they take samples of eluvial-de-eluvial deposits in the form of gravelly-sand fractions of 200-300 g weight. From a dried material of samples using a double screening by bolters with holes of 2.5-3.0 mm and 0.5-1.0 mm separate a faction of size of (2.5-3.0) + (0.5-1.0) mm, which is exposed to a mineralogical analysis on the contents of chips and a wreckage of chips of sulphidic minerals. Results of the analysis are assessed and on their base a decision is taken on availability of a deposit. The technical result is an increase of content of the elements - indicators in the samples taken within the limits of the deposit and outside it.

EFFECT: the invention ensures increased share of the elements - indicators in the samples taken within the limits of the deposit and outside it.
