Quests for dc ores

Can someone tell me all the quests below lvl 70 that give dc ores.
I know of the one in ludi that gives 3 dc ores?
But whats the name of it.
All help for dc ore quests is appreciated.

I don't think there are any other quests that give them. Wraiths in the subway drop dc ores though.

Mods can delete this i found a few other quests but its random.
And yes im grinding at wraiths.
