Results
Calculated Results:
Results are calculated using the following formula:
MetalEq (percent) = Gpri + (Gpri × [∑i Ri Si Vi Gi ]/(Rpri Spri Vpri Gpri))
where R is the respective metallurgical metal recovery rate, S is the respective smelter return rate,
V is metal price/tonne, and G is the metal commodity grade for the suite of potentially recoverable commodities (i) relative to the primary metal (pri)

This is really useful!..
Going to send this to my friend who will use it every day. Juts a quick note, maybe it’s only me, but seems to be a bit buggy in Firefox browser? Pushes down the screen a little bit when you calculate results.
I would really like to know the formula used to do these calculations. Specially how dealt with all the different units and ratios involved (grams, ponds, tonnes, ppm, percents…).
