Precursor Yield at 68% target precursor yield: a worked example

Suppose target precursor yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate precursor yield from recovered precursor mass versus theoretical or charged metal-equivalent mass for a co-precipitation batch or campaign.

The inputs for this scenario

  • Recovered precursor mass: 8 kg (held at the documented default)
  • Theoretical precursor mass from feed: 250 kg (held at the documented default)
  • Target precursor yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Precursor yield = recovered precursor mass ÷ theoretical precursor mass × 100.
  • Precursor yield works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Precursor yield gap to target works out to 64.8 points at these inputs.
  • Recovered precursor mass works out to 8 count at these inputs.
  • Theoretical precursor mass works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target precursor yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes precursor yield as recovered mass divided by theoretical mass, and reports the gap in percentage points to your target. 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.
