Abstract
The concept of sustainable development in the mining and mineral processing industry is primarily aimed at solving environmental protection problems through the transition to low-waste and waste-free technologies. One of the key approaches involves the utilization of previously accumulated industrial waste as secondary raw materials. This study presents experimental results on the production of Portland cement using flotation waste generated during the beneficiation of copper–molybdenum ores at JSC “Almalyk Mining and Metallurgical Combine.” Thermal activation of flotation waste was carried out in the temperature range of 700–900 °C with an isothermal holding time of 3 h. The results showed that the maximum pozzolanic activity of the flotation waste was achieved at 800 °C. Portland cements produced by joint grinding of clinker, thermally activated mineral additive, and gypsum demonstrated stable technological and mechanical properties and fully complied with the requirements of GOST 31108–2022. The utilization of flotation waste not only improves cement performance but also contributes to environmental protection and resource conservation.
