At Stoilensky GOK, the site of NLMK Group, a project is being implemented that will radically reduce the formation of dust on the dry beaches of the tailing dump - an area where waste rock is stored after ore processing. The new dust suppression system includes an adaptive water irrigation infrastructure and innovative treatment technology with a special reagent that suppresses the formation of dust even in windy conditions.

The dust suppression system consists of a network of pipelines and pumps for spraying water with a radius of 100 m. filling the tailing dump, the system can be quickly dismantled and moved to a new location. Sections of beaches removed from the irrigation system are treated with a reagent - organic glue, which sticks together waste rock particles. As a result, a dense crust forms on the surface, which retains dust in windy weather.

In 2021, more than six km of the irrigation system will be put into operation and more than one hundred hectares of the tailing dump will be treated with a reagent. Investments in the project will amount to RUB 150 million.
