Comparison analysis of propositions about problems of determination of industrial minimal content of components, related to “cocurrent” category, in polycomponent raw materials upon condition of its further complex processing has been realized. Conception and definition of limited content of every “basic” and “cocurrent” valuable product, defined upon the conditions of pay back of only direct addition expenses. The examples of determination of limited (discarded) contents of valuable components. At this base “State Committee of Minerals Reserves” confirms calculation of industrial resource with high estimation.

The researches have been executed with financial supports of Russian Humanitarian Scientific Fund and Government of Murmansk region as results of joint regional tenders (projects No. 09-02-43207a/C and No. 10-02-43207 a/C).
