The image above represents percentage recovery (assay). To calculate percentage recovery (assay), three essential parameters are needed and these parameters are Assay of Concentrate (c), Weight of Feed (f) and Assay of Tailings (t).
The formula for calculating percentage recovery (assay):
%R = 100(c(f – t) / f(c – t))
Where:
%R = Percentage Recovery (Assay)
c = Assay of Concentrate
f = Assay of Feed
t = Assay of Tailings
Let’s solve an example;
Find the percentage recovery (assay) when the assay of concentrate is 12, the assay of feed is 14 and the assay of tailings is 20.
This implies that;
c = Assay of Concentrate = 12
f = Assay of Feed = 14
t = Assay of Tailings = 20
%R = 100(c(f – t) / f(c – t))
That is, %R = 100(12(14 – 20) / 14(12 – 20))
%R = 100(12(-6) / 14(-8))
%R = 100(-72 / -112)
So, %R = 100(0.64)
%R = 64.28
Therefore, the percentage recovery (assay) is 64.28%.
