Various variants of the technological concept of using chromic waste as a substitute of natural raw materials, i.e. chromium ore and dolomite, in the standard process have been proposed. The object (process) function, valid in the researched area, was determined by assuming material balance equations (which describe each of the above-mentioned technological nodes) and by using the relations determined on the basis of experiment results. To work out this function the collections of values characterizing this function and a classification of these values were created.
