ing [25] and selective flocculation [26–28] have also been used for the processing of copper ore. It is evident in the literature that there is a lack of information on copper flotation, and most of the literature is confined to sulphide ore. The processing of oxide and mixed ores is minimal.The article presents research on the comminution of copper ore in a self-constructed mill using high-pressure water jet energy to investigate the usefulness of such a method for comminuting copper ore. As a result, ore particles are obtained that are characterized by appropriate comminution and a significant increase in their specific Energies Free Full-Text Comminution of Copper Ores with the Use

electric energy consumption, and 40% of the total energy consumption in the mining industry [7]. In Poland, the annual electric energy consumption from copper ore processing plants is approximately 2.5 TWh [8]. Primary ore comminution is performed with jaw and hammer crushers. Ore is then transferred to ball mills, in which it is first subjectedCopper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was Grinding Kinetics Adjustment of Copper Ore Grinding in an

While copper ore usually contains about 0.5–2% copper,the PCB itself contains 10–25% copper depending on the source and type of the circuit board . Unlike virgin ore, there are no or very fewer gangue minerals in the secondary resources, hence there is no need for an energy-intensive beneficiation process, and the flowsheet is The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and Chemical Composition Data of the Main Stages of Copper

The energy consumption values presented in this study were systematically lower than reported for average energy use of copper smelting. BAT documentation ( Cusano et al., 2017 ) provides the energy consumption range of 14–20 GJ/t Cu including the re-smelting of anode scrap and especially the tankhouse electrolysis A similar conclusion that the use of renewable energy is a key aspect for improvement was drawn by Sanjuan-Delmás et al. (2022) who analyzed the environmental impacts of European Cu mining and smelting production based on LCA. However, relevant studies on Cu mining and mineral processing in China are very limited.Environmental impacts and improvement potentials for copper mining

Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in Figure 3: 2050 Copper demand by energy Technology (%): (World Bank, 2019).. 15 Figure 4: Copper uses by end use sector: (Source ICSG The Figure 9: Copper Mining and Processing: Processing of Copper Ores (Source: University of Arizona).. 19 Figure 10: Declining copper grades over time (Source: MuddZero Emission Copper Mine of the Future Copper Alliance

The main concern in ore beneficiation and processing plants is producing the desired product size with the lowest possible energy consumption. It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations.The global market has announced copper as a modern energy metal and finds its extensive utilization in the construction industry, electrical wiring, power transmission lines, alloying, anticorrosive coating, heat exchangers, refrigeration tubing, etc. Copper ore is primarily beneficiated from sulphide mineral deposits.
