I have searched large portions of the world for any ore that can give chromium, but I haven’t had any luck. Are there any tips for finding chromium ores, i saw that they spawned in a basalt layer, but not much else. Any help would be apricated!

Try setting up a Sluice first, and then Centrifuge the Sluice Juice for Chrome. Basically ANY ore can be a Chrome Ore with the Sluice.
