By the late 1600's and early 1700's, iron ore was still being mined in ia and western Massachusetts. Small scale bloomeries, the most primitive form of smelting, reduced the ore into a porous mass of iron slag called bloom or sponge iron.The bloom was hammered into a low quality wrought iron by using hand held or large, heavy …

Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.

Iron Ore

Iron ore is an ore that can be mined from iron rocks. Iron rocks naturally generate in the mining zone in the Hub,Emerald Mines, Slime Island, Buffalkor Island, and the Diamond Mines. Mining an iron rock yields 1 - 2 iron ore per stage, resulting in a total of 2 - 4 iron ore. There's also a 1.5% chance that the rock drops crystallized iron. Iron totems can …

10.1.3 Smelting Copper

It is quite possible or even likely that only little slag was produced in very early copper smelting. Indications are that this was done on a small scale "at home", possibly by a few specialists, who had the ore brought in from wherever it was found. So the absence of slag does not necessarily signal the absence of small-scale smelting.

bloom from scale.

BTW, I expect that the bloom will be pretty much iron rather than forgable steel. I expect that you will have to work it down into wrought iron. The scale is pretty much iron oxides which will approximate iron ore. So, the process will be very close to getting metal from ore. "By hammer and hand all arts do stand."
