1. Flotation Flowsheets for Copper Ores in Mineral Processing

2. Introduction Overview of global copper production and key producers (e.g., Chile, China, Peru). Importance of flotation in processing low-grade copper sulfide deposits. Impact of flotation technology on copper industry.

3. Types of Copper Ores and Processing Techniques Overview of copper sulfide and secondary copper minerals (malachite, azurite). Influence of oxidation and reduction zones in ore bodies. Importance of flotation for porphyry copper deposits.

4. Basics of Flotation in Copper Processing Description of the flotation process for copper sulfides. Common reagents used: thiol collectors (xanthates), frothers, and pH control. Importance of grinding to optimize liberation.

5. Copper-Molybdenum Separation Techniques Overview of molybdenite flotation post-copper flotation. Challenges in molybdenite flotation: slime production, fine particle behavior. Reagents used for copper depression: sodium hydrosulfide, nitrogen gas.

6. Case Study: Highland Valley Copper (Teck Resources) Overview of the operation: ore grade, processing capacity, and outputs. Simplified flowsheet and equipment used. Details on bulk Cu-Mo rougher-scavenger-cleaner circuits.

7. Grasberg Operation: A World Leader in Copper and Gold Production Overview of the Grasberg flotation circuit and its capacity. Key minerals processed: chalcopyrite, gold, and silver. Flowsheet of the flotation process: roughers, cleaners, and scavengers.

8. Technological Advances in Flotation Introduction to larger flotation cells (e.g., Outotec tank cells at Chuquicamata). Benefits of using advanced flotation technologies in large-scale operations.

9. By-Product Recovery: Case of Palabora Mining Co. Overview of by-products: magnetite, uranium, zirconium. Flowsheet of the Palabora operation and its multi-product strategy. Role of coarse flotation feed in downstream recovery processes.

10. Common Challenges in Copper Ore Flotation Issues with slime production and fine particle recovery. Impact of reagent selection and usage on flotation efficiency. Strategies for overcoming challenges in different ore types.

11. Case Study Discussion: Improving Flotation Efficiency Present a hypothetical scenario where students must suggest improvements to a flotation circuit. Discuss potential solutions and their impacts on recovery rates and concentrate grades.

12. Summary and Key Takeaways Recap of the key points covered in the presentation. Importance of selecting the right flotation flowsheet for specific ore types. Future trends in flotation technology for copper ores.

13. Questions and Open Discussion Invite questions from students to clarify any points. Encourage discussion on the application of flotation technologies in different scenarios.

18. Sulfide Nickel Ore Seventy percent of land-based nickel resources are contained in lateritic deposits, though the majority of the world’s current production of nickel still derives from sulfidic sources ( Bacon et al., 2002 ). The dominant nickel mineral in these deposits is pentlandite—( NiFe )9S8. However, many ores also have minor amounts of millerite ( NiS ) and violarite (Ni2FeS4). Nickel can also. be found within the pyrrhotite (Fe8S9) lattice, substituting for iron.
