Aggregate Yield at 68% target aggregate yield: a worked example

Suppose target aggregate 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. Estimate aggregate yield for aggregate yield for bulk solids, mining, aggregates, and material processing using plant-floor material, production, quality, capacity, or cost inputs.

The inputs for this scenario

  • On-spec product recovered: 850 tons (held at the documented default)
  • Total feed processed in the same period: 1,000 tons (held at the documented default)
  • Target aggregate yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Aggregate Yield = aggregate yield accepted or affected material ÷ total ore, aggregate, powder, sand, gravel, fines, or bulk solid in same period × 100.
  • Aggregate Yield works out to 85 % at these inputs, and this is the headline figure for the scenario.
  • Aggregate Yield gap to target works out to -17 points at these inputs.
  • Aggregate Yield accepted or affected material works out to 850 count at these inputs.
  • Total ore, aggregate, powder, sand, gravel, fines, or bulk solid in same period works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target aggregate yield sits at 95% and the headline result is 85 %, this scenario lands almost exactly on the baseline at 85 %.
  • It divides on-spec recovered product by total feed processed in the same period and multiplies by 100, then subtracts the result from your target to show the shortfall in points. 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.
