Scrap Recovery Value at 50% recovery yield after reclaim: a worked example in rare earth magnet & motor materials

Suppose recovery yield after reclaim falls to 50%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the recoverable value from rare earth magnet scrap based on scrap mass, payable value per kilogram, and recovery yield.

The inputs for this scenario

  • Magnet Scrap Mass Recovered: 800 kg (held at the documented default)
  • Reclaimed RE Value per Kilogram: 45 $/kg (held at the documented default)
  • Recovery Yield after Reclaim: 50 % (the input this scenario stresses; the baseline uses 70)
  • Reclaim Processing Overhead: 2,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net recovery value = scrap mass x value per kg x recovery yield% + processing overhead.
  • Total scrap recovery value cost works out to 20,000 $ at these inputs, and this is the headline figure for the scenario.
  • Scrap recovery value cost per unit works out to 25 $ / piece at these inputs.
  • Variable scrap recovery value cost works out to 18,000 $ at these inputs.
  • Fixed scrap recovery value adder works out to 2,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where recovery yield after reclaim sits at 70% and the headline result is 27,200 $, this scenario comes in 26.47% below the baseline at 20,000 $.
  • It calculates net recovery value from a mass of magnet scrap, its per-kilogram reclaim value, the fraction actually recovered, plus the overhead of processing it. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total scrap recovery value cost: 20,000 $ (headline result)
