The use of discrete kriging in these conditions allows to ensure tightly controlled amountmore reliably, i.e., not less than 48% of Al2O3 content in the concentrate when shipping it from the processing plant onto bulk carriers. This problem isbecoming more and more urgent as the amount of field parts be ing rich is decreasing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>geostatistics</kwd><kwd>kriging</kwd><kwd>variogram</kwd><kwd>de Wijs’s model</kwd><kwd>variance of increment</kwd><kwd>the distribution of reserves</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">David M.
