The utilization or secondary use of technogenic waste is a relevant problem for the current economy. To assess environmental influence and economic potential, it necessary to study elemental content objects reveal tendencies spatial distribution elements, components, indices such as pollution coefficient. In this study, we performed analysis, calculation indicators: average gross content, hazard quotients, concentration coefficients metals, total ground samples taken from ash-slag storage Aksu ferroalloy plant [Aksu, Pavlodar region, Kazakhstan]. Maps concentrations elements were created. territory studied by level soil contamination should be considered an disaster zone. given statistical data on number oncological respiratory diseases indirectly indicated negative open waste. was chromium-manganese geochemical specialization. calculated volume accumulated mass approximating method 1 054 638.0 m 3 . approximate weight 23 679 576.0864 tons, including 822 972.2 tons chromium, 727 354.0 manganese, 953 813.3 iron. large amounts valuable components retained in led us conclude that object can field produce various technological products. Moreover, metals extracted metal concentrates.
