The Minimum Concentration Factor (MCF) depends on the minimum % for exploration. This means the minimum % of valuable ore needed to make mining profitable. For a mine to be profitable it needs to take in enough profit to pay for the amount of money needed for energy to retrieve ore and pay for all other costs related to mining (machinery, land costs, employees, etc).
The minimum % for exploration divided by the % percent in the crust yields the MCF. This value is very low for ore that are plentiful and easy to obtain, and get progressively higher for ore that are harder to mine and are not as plentiful in the crust.
