Abstract
This article explores the significance of coal mining and processing within the framework of the development strategy of the fuel and energy industry and the transition to a "Green Economy" in the Republic of Kazakhstan. It emphasizes the underutilized potential of rare metals present in coal and its by-products and discusses the importance of developing environmentally friendly technologies for their extraction. The article highlights the issue of ash slag waste from local thermal power plants and proposes ways for its rational utilization, including the extraction of rare metals. The Shubarkol coal deposit in Central Kazakhstan is considered a significant source of rare metals available for extraction during coal combustion. The article also underscores the need for further research and development in this area to maximize the environmental and economic benefits of using coal resources.
