3.57*. 1/28 (3.57%) Copper Ore is an early game ore, which spawns on the surface as well as in the Underground and Cavern layers. It is the weakest and most easily obtained tier of ore in the game. Its primary use is to make Copper Bars, which can be used to create the Copper tier of equipment. The equivalent of Copper Ore is Tin Ore, which ...

The gold recovery of the ore was improved from 57% to 80% during CIL, after the ore was treated with 4.48 mM naphthalene sulfonate at pH 11.3 adjusted by 4.36 mM Ca(OH) 2. The main factor, that was likely responsible for the improved gold recovery, was the passivation of the adsorption sites on the carbonaceous matter in the ore.
