ore or chromite ore

Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.

Chromite ore contains a mixture of complex spinel minerals and pyroxenes. Most of the chromium and iron in chromite is present as (Fe,Mg)(Cr,Al)2O4 spinel. A graphical representation of the spinel structure is given in Figure 2. Once the ore has been processed through a beneficiation plant, one is left with an ore or concentrate that

I remember getting the codex to mine Chromite Ore but can't find any source. Going through the "survival guide" doesn't show me chromite stuff but includes every other crafting material. It's gotta be there though, right? I've finished all the tombs.

Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR.

Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O 3. The content of Cr 2 O 3 for metallurgicalgrade chromite ore is in the range 42–55% and the chromiumtoiron ratio is higher than These quantities determine the chromium content in the smelted chromium ferroalloys.
