Gold Assay Recovery Calculator

Turn an assay into an expected recovery scenario. Enter the feed's contained gold and a process recovery assumption to estimate fine gold recovered and the value associated with it.

Expected Recovery Formula

Contained Fine Gold = Feed × Assay %
Expected Recovery = Contained Fine Gold × Recovery %
Unrecovered = Contained Fine Gold − Expected Recovery

Scenario Tool, Not a Guarantee

The recovery percentage is an assumption about process performance. It should come from historical runs, technical testing or an appropriate process model rather than being treated as a guaranteed result.

Why Assay and Recovery Work Together

A high assay does not automatically mean high recovered gold. The assay describes what is present; recovery describes how much of that contained gold is expected to make it into the recovered product.

Actual process results can differ from the entered recovery assumption.

Frequently Asked Questions

How is recoverable gold calculated?

Contained fine gold multiplied by expected recovery.

Is expected recovery guaranteed?

No.

Can expected value be calculated?

Yes, when gold price is entered.

Why use assay?

To calculate theoretical contained fine gold.
