Abstract
A process flow diagram for the complex differential extraction of precious and nonferrous metals from multi-component electronic scrap has been proposed for the purpose of improvement of the enterprise economic status in the secondary metallurgy. The advantages of the new technology and the results of extraction are given. The profit performances, which have been obtained as a result of introducing the technology, the together with the gold value as the main product during incidental extraction of other valuable components are presented. The efficiency coefficient of complex extraction of non-ferrous and precious metals is calculated by formula: K = Profit/Expenses. The effect of procurement prices on the profit is analyzed. The profit decrease per 1 ton of scrap is found to amount to 0,01 to 0,05 % with increasing the procurement price of up to 100 % for the content of precious metals at the rate of the Central Bank of Russia. Consequently, there is the possibility of significant growth of the procurement price for raw materials in comparison with the equilibrium prices of the market. The dependence of the annual profit on increased productivity for different scrap types has been analyzed. The compositions are recommended the procurement prices of which are to be increased. Realization the administrative impact on the scope of raw material supplies with the use of the pricing strategies is shown to be possible. The price increase for certain scrap types will provide the opportunity to attract suppliers, to increase the production, to expand the range of products, and obtain the additional income. Implementation of the proposed flowsheet for the complex recovery of valuable components from electronic scrap and the use of the raw materials procurement price increasing strategy for as a specific strategy for purchasing necessary resources and their distribution will allow us to improve the economic efficiency of the business activity. Increase in the profit will make possible the company to use it for realization of short- and long-term goals to improve their economic condition and strengthen the market position in the competitive environment.
