2. What is your comminution circuit throughput?

Please fill in the throughput of the mine in question. More detailed recent data (top of the list) is the most critical, but if you can provide information for all three boxes, please do so. If data may appear confusing, please add comments in the final field.

Year of production

Average hourly throughput (t/h)

Annual material milled (t)

Nameplate/design capacity (t/annum)

Comments

Year

3. What is your annual metal production rate?

Please fill in the metal production of the mine in question. If data may appear confusing, please add comments in the final field. This information can be found in annual or quarterly reports.

Gold (oz)

Copper (t)

Lead (t)

Zinc (t)

4. What is the annual total energy consumption of your mine?

Please fill in the total annual energy usage of the mine in question. The preference is to provide a breakdown of energy into electrical and diesel consumption, but if not available, please just fill in the total energy consumption. If the data is in different units, please provide the units or use conversion factors available Here. This data may be obtained from sustainability reports or from energy manager.

Year

Supplied (grid) electrical energy (GJ)

Renewable electricity generation (GJ)

On-site electricity generation (GJ)

Fuel consumed by electricity generators (GJ)

Fuel consumed by trucks (GJ)

Total energy consumption (GJ)

Electrical energy cost (US$/kWh)

7. What are the P80s down the circuit?

Please fill in the size through which 80% of the mass passes (P80) down the circuit of the mine in question. If P80s are not available down the circuit, feed and product will be sufficient. This information may be obtained from the plant metallurgist or as a last resort design specifications.

Blasted product (mm)

Primary crusher product (mm)

Final crusher screen undersize (mm)

SAG trommel undersize (mm)

HPGR screen undersize (mm)
