Electrowinning Energy Consumption
Derive DC and grid rectifier energy per kilogram from Faraday charge balance and caller efficiencies; auxiliary pumps and heating are excluded.
Description
Electrowinning deposits metal by passing electrical charge through a cell.
Electrowinning deposits metal by passing electrical charge through a cell. Faraday charge balance connects electron stoichiometry to metal mass, while cell voltage and efficiency determine electrical energy.1
The tool returns dcEnergyKwhPerKg, gridEnergyKwhPerKg. The computation uses supplied observations and parameters rather than acquiring measurements.
When to use Electrowinning Energy Consumption
Use this for the following task: Derive DC and grid rectifier energy per kilogram from Faraday charge balance and caller efficiencies; auxiliary pumps and heating are excluded. Prepare observations and calibration parameters on the same unit and reporting basis.
How to use Electrowinning Energy Consumption and understand its results
- Prepare the measured quantities and supplied model parameters. Match the units and align paired lists before calculating.
- Enter cellVoltage, electronStoichiometry, molarMassKgPerMol, currentEfficiency, faradayCoulombsPerMol, rectifierEfficiency according to the field table, then run the tool.
- Read dcEnergyKwhPerKg, gridEnergyKwhPerKg. Use the calculation below to interpret the selected mean or the model’s signs, units and comparison flags.
- Review the supplied assumptions and calibration before comparing or reporting the result.
| Input field | Meaning | Value type and bounds | Requirement |
|---|---|---|---|
| cellVoltage | Cell voltage | number | Required |
| electronStoichiometry | Electron stoichiometry | integer | Required |
| molarMassKgPerMol | Molar mass kg per mol | number | Required |
| currentEfficiency | Current efficiency | number | Required |
| faradayCoulombsPerMol | Faraday coulombs per mol | number | Required |
| rectifierEfficiency | Rectifier efficiency | number | Required |
Use positive voltage, integer electron count, molar mass in kg/mol and Faraday constant in C/mol. Current and rectifier efficiencies must be in (0,1].
DC kWh/kg = voltage×electronCount×Faraday/(molarMass×currentEfficiency×3,600,000); grid = DC/rectifierEfficiency The symbols and boundary conditions refer to the supplied fields and the implementation described above.
| Output field | Meaning | Value type |
|---|---|---|
| dcEnergyKwhPerKg | Dc energy kwh per kg | number |
| gridEnergyKwhPerKg | Grid energy kwh per kg | number |

}Limitations and assumptions
This estimates deposition and rectifier energy only. Pumps, heaters and other auxiliaries are excluded; electrochemical conditions and realistic efficiency values remain caller responsibilities.
Numerical inputs must be finite. Input-shape and calculation checks do not establish measurement quality or the validity of a supplied calibration.
Alternative or Complementary methods
Choose Metal Content when you need its operation: Calculate contained and recovered metal across dry-tonnage lots with grades in g/t; caller recovery fractions do not establish reserves or payable-metal terms. Choose Comminution Energy for the complementary operation: Predict corrected Bond net energy and power for supplied throughput; no-load mill power and hardware sizing are excluded.
