Precious Metal Yield at 99% target precious metal yield rate: a worked example
Push target precious metal yield rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use after a casting run or production batch to measure how much precious metal made it into saleable pieces. Compare your yield against your target to decide whether casting parameters, sprue design, or handling procedures need adjustment.
The inputs for this scenario
- Finished metal weight recovered: 210 grams (unchanged)
- Total precious metal charged: 250 grams (unchanged)
- Target precious metal yield rate: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Precious metal yield rate = finished metal weight ÷ total metal charged × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 84 % for precious metal yield rate, the number this scenario is built around.
- At this operating point the engine returns 15 points for yield gap to target.
- At this operating point the engine returns 210 count for finished metal weight.
- At this operating point the engine returns 250 count for total metal charged.
How this compares with the baseline
- Against the tool's baseline example, where target precious metal yield rate sits at 90% and the headline result is 84 %, this scenario lands almost exactly on the baseline at 84 %.
- It divides finished recovered metal weight by total metal charged to give a yield percentage, then shows the gap to your target yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
