Iron Ore
Iron Ore is an early-game ore that generates upon world creation on the Surface, as well as in the Underground and Cavern layers. Its primary use is in crafting Iron Bars, which can then be used to craft the Iron tier of tools, weapons, and armor, as well as Buckets, Chains, and several other items. The equivalent of Iron Ore is Lead Ore, which will sometimes replace Iron in a …

Effects of surfactants combination on iron ore flotation
Frothing has not been played by specific frothers in cationic flotation of iron ore. • Frothers surpass etheramines in reducing bubble size and increasing ability. • The partial replacement of the etheramines by frothers improved the selectivity. • The compatibility of molecular weight explains the improved selectivity. •
