What strategies do you use to optimize ore recovery and minimize waste?

Your Answer

How To Answer This Question?

When answering this question, it's important to demonstrate your understanding of both the technical and practical aspects of mine planning. Start by discussing the importance of optimizing ore recovery and minimizing waste in mining operations, such as improving profitability and reducing environmental impact.

Next, outline specific strategies you have used or would use. For example:

1. Geological Modeling: Explain how you use geological data to create accurate models of the ore body, which helps in planning efficient extraction methods.
2. Cut-off Grade Optimization: Discuss how you determine the cut-off grade to ensure that only economically viable ore is processed.
3. Selective Mining: Describe techniques for selectively mining high-grade ore while leaving low-grade material, thus reducing waste.
4. Ore Blending: Talk about how blending different grades of ore can optimize the overall quality and reduce processing costs.
5. Waste Management: Explain your approach to managing waste materials, such as using waste rock for backfill or creating waste dumps in environmentally safe locations.

Provide examples from your past experience where you successfully implemented these strategies. Highlight any measurable outcomes, such as increased ore recovery rates or reduced waste production. This will show that you not only understand the theory but also have practical experience in applying these strategies effectively.
