Эмиссия газов при производстве сырья для металлургии

Abstract

The concept of a through energy-ecological assessment of the entire sequence of processes in the production of a particular product in the form of technological fuel and technological environmental numbers is known. A similar estimate was introduced to characterize greenhouse gas emissions in the steel industry, these numbers are estimated in energy units, but to get the last two numbers you need to know the emissions of harmful and greenhouse gases. However, the contribution of the processes of extraction, enrichment and transportation of raw materials in the numerical estimates is approximately determined, while the technological processes in each quarry and mining and processing plant have their own characteristics. This paper attempts to clarify this contribution by determining emissions of harmful substances and greenhouse gases for a generalized open pit process scheme.
