Iron Concentrate is created by purifying Crushed Iron Ore. This can be done in one of two ways: either dry or wet purification, each of which can be performed using one of two crafting stations. The crafting stations come with different ratios, labor cost and time. The process to make Iron Concentrate also gives a by-product of either …
