The use of geostatistics to estimate the distribution of the reserves of one of the bauxite deposits of the Republic of Guinea

Abstract

To assess the content of Al2O3 in the exploration block of one area of Sangaredi bauxite field (the Repubtic of Guinea, West Africa), there was applied one of geostatistics method - discrete Kriging. The use of discrete Kriging in these terms altows for more reliability to provide tightly controlled value, namely, not less than 48 % Al2O3 content in the concentrate when shipping it with concentrator on bulk carriers. This problem becomes all the more urgent because of the rich oil field areas is becoming less.
