Question

Resuing method of mining is practiced for

• A. thick vein deposit.
• B. massive shallow deposit.
• C. narrow vein deposit.
• D. massive deep-seated deposit.

Hint:

Use resuing only where high selectivity is required, typically in very narrow ore veins.

Answer 1

The Correct Option is C

Resuing is a highly selective underground mining method used where ore and waste must be separated.

Step 1: In resuing, waste rock is blasted and removed first, then the ore is blasted separately to avoid dilution.

Step 2: This technique is necessary only when ore bodies are extremely narrow, and mixing waste with ore would drastically reduce grade.

Step 3: Thick or massive deposits do not require such selectivity.
Therefore, resuing is practiced for narrow vein deposits.
