What is meant by ‘predicting yield of a commercial ore deposit?

Answer 1

An ore is not a pure material. Only a fraction of it is the material you want. Predicting the yield means taking into account the percentage of the pure material found in the ore.

Example:
A sample of iron ore contains 60% iron. Predict the yield of iron if 10 tons of this ore is mined and refined.

Answer:
60% of 10 tons is the iron yield.
0.60 x 10 tons = 6.0 tons of iron
