Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 ...

what type of reaction is this? | Wyzant Ask An Expert

About this tutor ›. 3C + 2Fe2O3 --> 4Fe + 3CO2. This is an oxidation/reduction reaction, where C is oxidized (loses electrons) and iron is reduced (gains electrons). C goes from oxidation number zero on the left to oxidation number 4+ on the right. Iron goes from oxidation number 3+ on the left to zero on the right. Upvote • 0 …

Refining | Mabinogi Professional Wiki | Fandom

While the ore you unearth is nice and hard, you can't do anything with it if it contains metal, dirt, and sand mixed into it. Not only does it make it difficult to build metal products of adequate quality, it is also difficult to produce even any results. Therefore, in order to use metal, a process in which pure metal is gained from ore is essential. This is where the …

Metallurgy

The procedure is accomplished in three ways: refining by fire, by electrolytic, or by chemical methods. Iron, copper, and lead are fire-refined by selective oxidation. In this process, oxygen or air is added to the …
