The technology is new and makes a certain contribution to the development of science and technology for the integrated use of raw materials, the creation of low-waste technologies while simultaneously solving the problem of environmental protection. As a research hypothesis, it was established that the greatest influence on the copper content in the converter slag is exerted by the magnetite present in it in significant quantities. Magnetite heterogenizes the melt, increases the viscosity and density of the melt, as a result of which the reduction processes are very difficult. It is assumed that the carbon-thermal reduction of the melt magnetite should contribute to the successful reduction of the copper concentration in industrial waste. The developed technology of a significant reduction in the concentration of copper in the converter slag significantly increases the complexity of the use of raw materials, helps to remove part of the metal from the work in progress, reduces the ballast turnover of metal in the reverberatory furnace - converter cycle and can provide an economic effect of more than 10 million US dollars per year.
