I've done an orbital survey, and choose the farside crater as the place for the base, as it had the second highest ore concentration, and was at the equator. I have successfully landed my first rover equipped with a surface scanner. I've found ore concentrations in the 3 4% range so far.
Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component.
In southern Africa, two x ray sorters are used to pre concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
The copper concentration in copper ore deposits has shown changes throughout history. From 1880 to about 1960 the grade of copper ore showed a steady decrease from about 3% to less than 1%, mainly due to increased efficiency of mining.
