As background values, the content of chemical elements in the soils of the Khakassia biogeochemical province was taken [1]. When compared with the soil composition data of the Khakassia province [5], it is determined that for most soils of both autonomous and subordinate landscapes, the content of cobalt and copper at the time of the investigation is close to provincial (table 2). Average content in the soils of the Khakassia province,. in the numerator – autonomous positions, in the denominator – heteronomous).

Blast reduction smelting
The practice of the existing metallurgical company is to smelt lead concentrates and intermediate products in the ISA furnace, which replaced the traditional environmentally harmful blast furnace smelting technology, which increased the processing efficiency of the concentrates, as well as improved the capture efficiency . SO2 and uncontrolled lead emissions. One of the causes of losses can be the presence of contaminations in the recycling streams that cause a change in the original composition of the materials to be recycled. The work of the researchers is aimed at improving this section not only in the framework of reducing losses during the melting process and identifying the sources of losses, but also in reducing the evaporation of impurities such as As and Sb that should happen as soon as possible. possible life in the process, and preferably inside the melting furnace, so that they do not contaminate the industrial environment and do not interfere with the operation of downstream equipment.
Mechanical losses are entrained metal droplets that do not settle and end up in the underlying matte or metallic phase [6]. The reductant in the blast furnace uses carbon monoxide (CO) gas, which is produced by burning the coke loaded in the furnace. At the first stage, the sandblasting work period is twelve months in 2018.
The minimum number of blast furnace returns has been loaded halfway through the year and the input recorded in the last month of the year has been reached. The monthly processing of the mixture of explosion reduction smelts (lead ISA slag, iron concentrate) ranges from 35.5 thousand tons to 41.1 thousand tons. It depends on increasing or decreasing the process involved in turning back blast furnaces. This circulation is increasing due to an increase in the production and processing of revert material in the three months of 2018 (September, November, December).
Possible reason for this could be a change in the composition of the mixture, including the lead content in input ISA slag. It was revealed that with the decrease in the lead content of the mixture of lead-ISA slag, iron concentrate, the yield and accordingly the processing of blast furnace resets increases. The increase in the share of blast furnace return in charge reduces the output of the target product of blast furnace.
In order to determine the sources of losses and the reasons for the decrease in production of the target product, the technological flow sheet of pyro-metallurgical processing of lead-containing materials was analyzed. In order to determine the main patterns and factors that can have a significant impact on the optimization of the existing technology, allowing to increase the efficiency of the use of resources, the main parameters of the detonation reduction melting process were reviewed in the period January-December 2018.
