Crushed Iron Ore - ECO - English Wiki

2020-11-30  Crushed Iron Ore is created by crushing Iron Ore in one of three different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The two lover crafting stations also have a byproduct of Crushed Sandstone. Crushed Iron Ore needs to be further refined to Iron Concentrate before it can be smelted into an Iron Bar.

Zinc: smelting, producing and classification-Metalpedia

Zinc is found in the earth’s crust primarily as zinc sulfide (ZnS). Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals.
