Development of technology for smelting manganese-containing ferroalloys using unconditioned iron-manganese raw materials. The study solves the problem of recycling non-conditioned iron-manganese raw materials and carbon waste. The chosen direction allows to solve the problem of utilization of carbon and silica raw material waste, and also to obtain the melting indicators of ferroalloys at a much better level than using traditional expensive carbon reducers. In addition to utilization of undemanding small fractions of carbon and silica raw materials, this direction allows to additionally solve the following tasks: – improvement of the quality characteristics of the produced product; – increasing the technical and economic indicators of silicon ferroalloy smelting production due to optimization of the composition of charge materials. In the case of the Republic of Kazakhstan, relatively low technological indicators of smelting ferrosilicon and ferrosilicomanganese alloys using traditional types of carbon reducers are prerequisites for project development. It is recommended to use carbon composite materials made from coke, semi-coke and low-ash coal with additives of active siliceous materials as a carbon deoxidizer. At the same time, there is an opportunity to increase the specific electrical resistance of the mixture of charge materials, the power of electric furnaces, the rate of recovery of silicon and the technical and economic indicators of smelting

The technology of smelting manganese-containing ferroalloys using briquettes is of interest to ferroalloy plants and enterprises. The expected economic efficiency when using the technologies developed in the ferroalloy industry consists in reducing the cost of production while increasing the productivity of electric furnaces. The cost reduction of the product is carried out due to the use of briquettes made from raw materials containing infertile iron-manganese. Productivity increase will be a consequence of increasing the power of electric furnaces due to the required electrophysical properties of briquettes. Environmental efficiency during the implementation of the scientific project and the introduction of technologies developed in industry will consist of the use of non-conditioned iron-manganese materials, their involvement in metallurgical redistribution. Accordingly, the environmental load will be reduced in mining enterprises and nearby areas. In the scientific and technical plan, a scientific base for the use and preparation of briquettes will be developed. The scientific and technical efficiency of the scientific project corresponds to the national project “Technological breakthrough due to digitization, science and innovation” and is aimed at the development of mining, coal processing and ferroalloy enterprises of the Republic of Kazakhstan. When using developed technologies for melting manganese-containing ferroalloys using experienced briquettes, the multiplicative effect consists not only of increasing the power of electric furnace units, but also of increasing the output of leading elements and, accordingly, increasing the qualitative characteristics of the melted product. New non-conventional ferro-manganese raw materials processing enterprises will create social and economic impact. In the implementation of the project, a new software complex will be used for thermodynamic modeling of technological processes, which will significantly reduce the number of experiments required for the development of technologies for smelting manganese-containing ferroalloys.

The research has a perfect novelty and prospects in terms of improving the technical and economic performance of smelting manganese-containing ferroalloys. At the same time, the problem of using substandard ferromanganese raw materials, as well as waste disposal of carbonaceous raw materials, will be solved. The applicability and commercialization of scientific results will be at a fairly high level. The developed technology for smelting manganese-containing ferroalloys using briquettes will be of particular interest to ferroalloy plants and enterprises. The expected economic effect of using the developed technology in the ferroalloy industry will be to reduce the cost of production while increasing the productivity of electric furnaces. The cost of production will be reduced through the use of briquettes from substandard ferromanganese-containing raw materials. The increase in productivity will result from an increase in the power of electric furnaces due to the required electrophysical properties of the briquettes. The environmental effect of the scientific project and the introduction of the developed technologies in industry will consist in the use of substandard (man-made) ferromanganese-containing materials and their involvement in metallurgical conversion. Accordingly, the environmental burden on mining enterprises and nearby territories will decrease. In scientific and technical terms, a scientific base for the use and manufacture of briquettes will be developed. The scientific and technical effectiveness of the scientific project corresponds to the national project "Technological breakthrough through digitalization, science and Innovation" and is aimed at the development of mining, coal refining and ferroalloy enterprises of the Republic of Kazakhstan. When using the developed technologies for smelting manganese-containing ferroalloys using experimental briquettes, the multiplicative effect will consist not only in increasing the capacity of electric furnaces, but also in increasing the extraction of leading elements and, consequently, improving the quality characteristics of the products being smelted. The possibility of launching new enterprises that will process ferromanganese-containing raw materials related to substandard (man-made) waste will create a social and economic effect. The project will use a new software package for thermodynamic modeling of technological processes, which will significantly reduce the number of experiments required to develop technologies for smelting manganese-containing ferroalloys. Thermodynamic modeling will make it possible to predict the qualitative and quantitative parameters of the course of reduction reactions, the distribution of elements by metallurgical phases in high-temperature conditions of smelting manganese-containing ferroalloys, as well as reduce time-consuming experiments with solving important technological problems based on the use of new software systems with an expanded database.
