Mining Dilution Calculator

STEP BY STEP

How to use mining dilution calculator

1. Enter your measured values in the displayed units.
2. Review the calculation: Dilution = waste / (ore + waste) × 100. Also report waste / ore × 100 separately.
3. Read the result and compare with the example.

WHEN IT HELPS

Common uses

• Check the worked example: 900 t ore + 100 t waste: dilution 10%; waste/ore 11.11%.

IN PRACTICE

Example

900 t ore + 100 t waste: dilution 10%; waste/ore 11.11%.

GOOD TO KNOW

Why do dilution percentages differ?

Some reports divide by ore tonnes; others by total mined tonnes. This tool labels both denominators explicitly.
