Model what happens to a jewellery batch when old gold is remelted and additional gold or alloy is added. Track total batch weight, fine-gold content and resulting purity.
The remelting model tracks fine gold separately from total material. The added material can be pure gold or another alloy, and a process loss percentage is then applied to the combined fine-gold amount.
Adding high-purity material can raise overall purity, while adding lower-purity alloy can reduce it. Process loss affects the fine-gold balance according to the assumption used in the model.
Run different added-material scenarios before a production batch is prepared. That lets you see whether the resulting purity moves toward the intended alloy specification.
Yes. Enter 100% as the added material purity.
Yes. Enter its estimated gold purity.
No. It models the mass and fine-gold balance from your assumptions.
