The image above represents enrichment ratio. To calculate enrichment ratio, two essential parameters are needed and these parameters are Assay of Concentrate (c) and Assay of Feed (f).

The formula for calculating enrichment ratio:

r = ^c / _f

Where:

r = Enrichment Ratio
c = Assay of Concentrate
f = Assay of Feed

Let’s solve an example;
Find the enrichment ratio when the assay of concentrate is 21 and the assay of feed is 7.

This implies that;

c = Assay of Concentrate = 21
f = Assay of Feed = 7

That is, r = ^c / _f
r = ²¹ / ₇
r = 3

Therefore, the enrichment ratio is 3.

Calculating the Assay of Concentrate when the Enrichment Ratio and the Assay of Feed are Given

c = rf

Where:

c = Assay of Concentrate
r = Enrichment Ratio
f = Assay of Feed

Let’s solve an example;
With an enrichment ratio of 12 and an assay of feed of 4. Find the assay of concentrate?

This implies that;

r = Enrichment Ratio = 12
f = Assay of Feed = 4

c = rf
So, c = 12(4)
c = 48

Therefore, the enrichment ratio is 48.

Calculating the Assay of Feed when the Enrichment Ratio and the Assay of Concentrate are Given

f = ^c / _r

Where:

f = Assay of Feed
r = Enrichment Ratio
c = Assay of Concentrate

Let’s solve an example;
Find the assay of feed when the enrichment ratio is 8 and the assay of concentrate is 40.

This implies that;

r = Enrichment Ratio = 8
c = Assay of Concentrate = 40

f = ^c / _r
So, f = ⁴⁰ / ₈
f = 5

Therefore, the assay of feed is 5.
