Abstract

The paper is based on experience of carrying out ecological and geochemical research in impact areas of the ‘Karelsky Okatysh’ plant and directly in production workshops. Mineral composition of ores is estimated quantitatively. Dynamics of ore delivery to the plant in 2005 is studied. Environmentally hazardous types of ores are revealed. Environmentally hazardous minerals are determined and levels of toxic element accumulation in these minerals are estimated. High concentration of several toxic heavy elements was revealed in dust accumulations of electrostatic cleaners in the pellet production workshop. Comparison of polluting element contents in the second and the third cleaners with the first roasting kiln and all the three kilns is given. Contents of a number of toxic elements exceed the Clarke level of the earth’s crust as well as maximum permissible concentration.
