Two-exponential model of ferroimpurities extraction during magnetic inspection of these impurities content in various media

Abstract

Abstract. Illustrative examples of process media for which the key mass-operational characteristics of magnetophoretic control of ferroimpurities (represented in test semilogarithmic coordinates) are not subject to the basic (one) exponential model are presented and analyzed. The concept is described and implemented of a two-exponential model that assumes the desuperposition of the key control characteristic (for two subfractions of ferroimpurities). The possibilities are demonstrated of performing practical mass calculations of ferroimpurities in a process media sample and corresponding values of their concentration in this media.
