What is chromite used for?
Uses of Chromite and Chromium. Thin coatings of chromium alloys are used as platings on auto parts, appliances, and other products. These are given the name “chrome plated .”. It is also used to make superalloys that can perform well in the hot, corrosive, and high-stress environment of jet engines.
Is chromite and chromium the same thing?
Chromite is a related term of chromium. As nouns the difference between chromite and chromium. is that chromite is (mineral) a dark brown mineral species with the formula fecr 2o 4 while chromium is a metallic chemical element (symbol cr) with an atomic number of 24.
What do you use chromite for?
Chromite can be used as a refractory material, because it has a high heat stability. The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys , nichrome, and stainless steel.
What does chromite mean?
Definition of chromite 1 : a black mineral that consists of an oxide of iron and chromium and is the only chromium ore 2 : an oxide of divalent chromium
Chromite is used as a refractory in the production of steel, copper, glass and cement. Chromite occurs as a primary accessory mineral in basic and ultrabasic igneous rocks.
What is refractory chromite?
Refractory grade CHROMITE is mainly used in chrome-magnesia or magnesia-chrome bricks. The high chromium content of typical 48% Cr2O3 and low silica of typical 0,9% SiO2, coarse sizing and high Cr:Fe ratio of close to 2:1 makes our refractory grade being appreciated world-wide.
Where can chromite be found?
The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe.

Is chromite valuable?
Chromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections.
What is chromite English?
1 : a black mineral that consists of an oxide of iron and chromium and is the only chromium ore. 2 : an oxide of divalent chromium.
How is chromite extracted?
Mining of chromite is carried out by open-pit and underground mining. Whereas open-pit mining is generally applied to podiform deposits, underground mining is applied to stratiform deposits.

What is the chemical formula for FECR 2 O 4?
It can be represented by the chemical formula of FeCr 2 O 4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4 ).
Is there a formula for the chemical formula of vinegar?
When we talk about Vinegar formula there are many questions that arise sometimes. Since vinegar isn’t a single chemical substance and includes a mixture of several different substances in the form of a solution there are chances of presenting each with their own formula. However, this is not done as it can be ambiguous.
What is the chemical reaction of FeCr2O4 and NaOH?
The main chemical reaction for this mixture is: 4(FeO ⋅ CrX2OX3) + 8NaX2COX3 + 7OX2 ⟶ 8NaX2CrOX4 + 2FeX2OX3 + 8COX2. Keep in mind that (FeO ⋅ CrX2OX3) is representing FeCrX2OX4 in this equation and NaX2COX3 replaces NaOH in OP’s equation.
How is the conversion of FeCr2O4 to nax2crox4?
However, the other answer is acceptable since OP’s main focus is on the first reaction of converting FeCrX2OX4 (one of the products from initial reaction of chromium (VI) waste) to NaX2CrOX4. Because these reactions are done in high temperatures (usually, 1000 − 1200 ∘ C; Ref.1), I’d like to make few comments:
