Estimate how much metal can be recovered from mixed processing waste using waste weight, metal content, separation efficiency and process losses.
Optional value inputs help estimate the economic value of the recovered metal.
The calculation estimates contained metal first, then applies the recovery rate to determine recovered metal.
The calculator first estimates the amount of target metal contained in the mixed processing waste. It then applies the entered recovery rate to that contained metal.
The resulting recovery percentage describes the fraction of contained target metal that is successfully recovered by the assumed process.
Metal content and recovery rate are different measurements. Metal content describes what is present in the incoming waste, while recovery rate describes how effectively the recycling process captures that metal.
For example, 1,000 kg of mixed waste containing 80% target metal contains approximately 800 kg of metal before processing losses. At a 92% recovery rate, approximately 736 kg of that contained metal would be recovered.
Two recycling processes can receive the same waste stream but produce different recovered quantities because of differences in separation equipment, material preparation, contamination, particle size, operator practices and process conditions.
A higher recovery rate generally means less of the target metal remains in the residual waste stream.
Mixed processing waste can contain target metal together with non-metal material, contaminants, cutting fluids, dust, oxides, plastics or other residues. The actual composition depends on the source and processing method.
Use a measured or reasonably supported metal-content estimate whenever possible. A laboratory analysis, material balance or historical recovery data may provide a better basis than an arbitrary percentage.
The unrecovered-metal figure represents the portion of estimated contained metal that is not captured at the entered recovery rate.
This figure should not automatically be interpreted as material that is completely lost. Some may remain in residues and could potentially be recovered through additional processing.
Suppose a recycling operation processes 1,000 kg of mixed waste with an estimated 80% target-metal content. The contained metal is approximately 800 kg.
If the process recovery rate is 92%, the estimated recovered quantity is approximately 736 kg.
The remaining 200 kg of the original waste is estimated to be material other than the target metal under the entered assumptions.
An optional recovered-metal value can be used to estimate the gross material value represented by the recovered quantity.
This is a gross material-value estimate and does not represent recycling profit. Processing, transportation, sorting, labor, equipment, disposal and other costs would need to be considered separately.
Recovery performance can sometimes be improved through better segregation, feed preparation, equipment settings, material classification and process monitoring.
Before changing a process, compare actual input composition, recovered output and residual waste through a consistent material-balance method.
Confusing recovery rate with metal content: These are separate percentages and should not be treated as interchangeable.
Applying recovery to total waste: Recovery should normally be applied to the target metal contained in the waste, not automatically to the entire mixed-waste weight.
Using an unsupported metal-content estimate: Poor input composition data can distort the recovered-metal estimate.
Assuming residual material is worthless: Unrecovered metal may remain in residues and could potentially have further recovery value.
Ignoring contamination: Recovered output may still require quality grading or additional processing before it can be sold or reused.
This calculator provides a mathematical estimate using user-entered waste weight, metal content and recovery assumptions. It does not analyze the physical composition of waste or independently verify recovery performance.
Actual recovery can vary with material composition, contamination, equipment, operating conditions, particle size and separation method.
What is metal recycling recovery rate?
It is the percentage of contained target metal that is successfully recovered by the recycling process.
How much metal can be recovered from mixed waste?
It depends on the total waste quantity, metal content and actual process recovery rate.
What is the difference between metal content and recovery rate?
Metal content describes how much target metal is present; recovery rate describes how much of that metal is captured.
Can this calculator handle mixed processing waste?
Yes. Enter the total waste, estimated target-metal content and recovery rate.
Does 100% recovery mean all waste becomes metal?
No. It means all estimated contained target metal is recovered. Non-metal material remains outside the recovered-metal calculation.
Can I calculate the value of recovered metal?
Yes. Enter an estimated recovered-metal value per kilogram to calculate gross material value.
