Economic Settings: Product Recovery

To access this screen:

  • Display the Economic Settings and select any product tab.

  • Select a processing method.

  • Click Parameters.

  • Select a product tab.

Note: The Costs tab of this screen relates to processing costs for the previously defined processing methods for the selected ore type. See Economic Settings: Processing Costs.

The settings on this screen are specific to a product, allowing you to define recovery settings as a fraction of the total processing costs, or based on the results of a defined formula.

Activity steps:

  1. Display the Product Recovery screen for the appropriate product.

  2. You can either enter a recovery Fraction (not a percentage on this screen) or use a Formula. Whether defined directly, or by a formula, recovery fraction can never exceed 1.

    • Select Fraction to enter a fixed fractional value. You can also specify a Delayed Recovery value using the Delay Recovery screen.

    • Click Formula to either Set Formula (if none exists) or Edit Formula (if one already exists. See Formulae.

      Note: In some cases, formulae may not work properly if the decimal symbol is set to comma (,) rather than period (.) in the Windows Regional settings.

  3. Optionally, set a product-specific Additional (downstream) processing cost. This can be defined either as an explicit Unit cost value ($/g) or a Formula.

  4. Define Optional Parameters:

    • Include <Product> in the cut-off tests – If you have multiple products and have opted for direct control of cutoff grades, you can exclude some products from the tests. To exclude this product, uncheck this.

    • Minimum cutoff – The effective cutoff is set to the greater of two numbers; the value entered here and the Economic Cutoff. This option is available only with the ore tests other than Revenue exceeds Rehabilitation Costs.

    • Maximum cutoff – The effective cutoff is set to the smaller of two numbers; the value entered here and the Economic Cutoff. This option is available only for ore tests other than Revenue exceeds Rehabilitation Costs.
