The article presents the results of analyzes to study the possibility of extracting valuable components from industrial waste from non-ferrous metallurgy. Of particular interest for the production of new types of products, in particular lead and additional extraction of precious metals (gold, silver), are the fine converter dust of the copper smelting plant of Almalyk MMC, the accumulation of which necessitated the search for technical solutions for their processing. Dust captured in electrostatic precipitators mainly contains metal sulphates, which violate the autogenousness of the melt and contribute to a decrease in the process temperature.

In this article, Tourism refers to the service sector, which is one of the fastest growing sectors of the economy.  It is said that the rapid growth of tourism in Uzbekistan will have a positive impact on the economy by providing large amounts of foreign exchange earnings and will allow the development of the country's tourism industry.

Methods of solving mathematical models of industrial enterprises using the simplex method, which is one of the most important methods of constructing mathematical models, are shown in finding optimal solutions to economic problems.

This article develops the opportunities for use of the idea as a strategy for mental impact in sports training. A hypothetical thinking for its particular applications is made, because of the unique elements of the games action. The need of a deliberate and exact methodology by the game educator is demonstrated, with a view for accomplishing the legitimate improvement of the understudies and a singular beneficial outcome.

The utilization of regarded metropolitan wastewater as an asset for water system water is a training generally utilized in bone-dry and semi-bone-dry areas of the world yet additionally one that is relied upon to turn out to be more diffuse because of the decrease of water assets and the peak in the opposition for water. Scientists' inclinations are, consequently, centered around exploring the impacts of the strategy under question on the yields on which it is applied. This audit presents the principle research discoveries on the subject with an uncommon reference to investigate completed in Greece. The overall finish of the current audit is that the utilization of treated metropolitan wastewater in water system can effectsly affect most harvest yields, given that quality attributes of both treated wastewater and yields are adequately observed.
