Influence of possible fluctuations of a chemical composition of waste of galvanic productions on the mixed iron oxide pigment (MIP) main pigmentary properties is established. It is shown that introduction of samples of MIP with the raised content of these or those metals in such industrial paintwork materials as alkyd PF-115 enamel and a primer GF-021, practically doesn't change physic-mechanical properties and firmness of the coverings received on their basis. It allows to apply slimes of galvanic productions as the main raw materials by industrial production of MIP and to reduce prime cost of a pigment by 15-20%.
