摘要

Systematic water accounting frameworks, such as SEEA-W, play a pivotal role in optimizing water resource management in the mining industry. This study focused on the concentration section of the Sarcheshmeh Copper Complex and applied the SEEA-W framework to systematically organize and analyze all water inputs and outputs for the years 2021 and 2022. During this process, previously unmonitored water flows were identified and the necessary flow meters were installed to ensure continuous and reliable measurement. The results indicated that ≈ 81 to 83% of water used in the concentration section was sourced from recycled streams. Despite a 0.09% increase in ore input, water consumption in the concentration process decreased by 0.68%, while copper-molybdenum concentrate production increased by 0.39% and the final copper grade was improved by 0.62%. Operational performance indicators improved by 1.36% in 2022, with a two-year average operational efficiency of 83.5%. Enhanced thickener performance, particularly through the selection of an optimal flocculant powder, contributed greatly to the reduced water consumption. The study demonstrates that implementing the SEEA-W framework allows precise assessment of water use, recycling, and operational efficiency in industrial units. By providing transparent and comparable data, it establishes a foundation for informed management decisions and supports the development of sustainable water policies.
