G'day 30kg of ore - call it a rock collection, there is not much use unless you can get a lot more and flog it to a mine. Trying to smelt or refine it you would first need to separate the galena from all the other minerals in the ore. They will be there even if you can't see them - best done in a complex set up of spirals and floatation.
