Hydrometallurgy To Analyze Aa Sample Of Chromite

Hydrometallurgy to Analyze a Chromite Sample
:
Chromium can be use in the production of stainless steel and other nonferrous alloys in order to enhance their harden ability and to make the alloys more resistant to corrosion and oxidation. It can also be apply to plate metals, make pigments, accomplish leather, catalyze, and treat surfaces. Chromite is the only ore of chromium. Chromite is bid magnesium chromium oxide. Metallurgy can be employ in order to recover the chromium from the chromite ore.
This experiment is being performed in order to determine if an unknown attempt is actually chromite. In order to do this, the sample must be marooned using hydrometallurgy. This process consists of extraction of the metal by dissipation the metal in a solvent. The metal must then be recovered and the waste discarded. This can be make by leaching, separating the separating the waste and purifying the leach response, then precipitate the the metal or one of its pure compounds from the leach root word by chemical or electrolytic mean.
Once this process is done, it can be determined if the sample is actually chromite or non. If the sample contains, magnesium, iron, and chromium, then the sample is indeed chromite. However, if the sample does not contain all of these, then it cannot be chromite.





Experimental:
in all participants in the experiment must be wearing sentry duty glasses, long pants, closed toe shoes, and a shirt.
The sample may be mineral chromite. Tests should be done to determine if the sample contains magnesium, iron, and chromium (chromites components).
A spectrophotometer may be used to determine if iron and chromium are in the sample, unless magnesium neither absorbs nor emits light energy in the 200-900nm section of the spectrum so it can not be determined by a spectrophotometer.
Magnesium must be isolated and precipitated by dint of the process of extraction.
Chromium must be extracted first.
Put 2.5mL of 4.0M NaOH solution into a graduated cylinder.
