The Assaying of Wastes and Perfecting of Measures on a Heightening Ecological Safety at Production, Opening-up and Use of Fluxing Stones in Iron and Steel Industries

The Superviser - associate professîr Rostovski Vladimir Ivanovich


The reason of impurity of natural environment during the base operations of production and opening-up of fluxing stones for a metallurgical treatment are analysed in scientifik work. The radiants of formation, runout and physic-chemical properties of wastes of production of fluxing stones on an example "Novotroisk's a mine group " are surveyed also.

The special attention is given to mining of measures on meliorating an ecological situation of territories, around the operations of fluxing stones production the operations.

    Directions of exploration:

  • perfecting of the circuit of upgrading of buhrs in requirements of a crushing - preparation plant " Novotroisk's a mine group ";

  • mining technology of salvaging both storing of wastes of production and upgrading of buhrs;

  • the meliorating of working conditions in industrial locations plant

  • architecture of a reverse cycle of water facilities at plant.

The ecological problems arise by manufacture of lime on leases of the metallurgical operations. The wastes of roasting leases are a dust after clearing process gases, fines breeze of lime (0-8mm), and aspiration calcareous dust. A catching, assembly, outswapping and the salvage introduces a major problem. These wastes can be utillized in agglomeration manufacture for intensification of a sintering process of mix material and for opening-up of wet slurries for salvaging. Use of limy mixes in an agglomeration sintering promotes intensification of a sintering process and meliorating of quality of a sinter. It proves to be true by results of laboratory explorations. The emissions of a dust in an atmosphere are eliminated thus.
