Abstract
An analysis of methods of determining the prime cost of a krypton–xenon mixture produced as a byproduct of air separation is given. The oxygen production of a large metallurgical enterprise is selected as the subject of study. A comparison of well-known methods of calculation is carried out and the basic sources of the cost of producing the mixture are analyzed. The components of the prime cost of krypton-xenon concentrate obtained on Khrom plants are investigated. It is found that energy represents the principal cost item, amounting to more than 80% of the total sum.
