- explain why ores and non renewable resources
- describe the separation processes, chem reactions and energy considerations involved in the extraction of copper from one of its ores
- recounts steps to recycling aluminium

- discuss importance of predicting yield in the ID , mining and extraction of commercial ore deposits
- justify the increased recycling of metals in our society and across the world
