Separation Of Sulphide Ores

Immiscible sulfide drops can become segregated and form immiscible magma layers in a magma chamber in the same way that cumulus layers form then when layers of sulfide magma cool and crystallize the result is a deposit of ore minerals of copper nickel and platinumgroup metals in a gangue of an iron sulfide mineral Among the ore deposits
