Hydrometallurgy To Analyze A Chromite Sample

Hydro surfacelurgy to Analyze a Chromite Sample Introduction: Chromium is a metal-looking part that is used for many industrial purposes, such as metal plating, leather processing, pigments, surface treatments, refractories, and catalysts. The only ore of chromium is the mineral chromite, or iron magnesium chromium oxide. In draw to utilize chromium, it essential be extracted from the chromite ore. The process of removing a metal(prenominal) element from its ore is called extractive metallurgy. One get to of extractive metallurgy, called hydrometallurgy, uses aqueous solution chemis essay for the recovery of metals from salts minerals or ores. The first spirit of hydrometallurgy, called origin, is the process of removing metal from the ore. This is d angiotensin-converting enzyme by dissolving the metal in a capable solvent, recovering the metal from the solution, and discarding the glom materials. The first step of extraction is l individuallying, in which the met al is dissolved in piddle or acid. Then the leach solution is purified by separating the waste from the coveted materials. The final step is precipitating the metal, or one of its pure(a) compounds from the leach solution by chemical or electrolytic capacitor means. This laboratory is focused on determining whether an unfathomed try is chromite or non.

Chromite contains magnesium, iron, and chromium, and it must be determined if the sample contains each of these metals. In order to do that, each metal must be extracted separately. There are several grand concepts that exact to be understood in order to pre miscellan ea this lab success completey. First, some m! etals are amphoteric. Amphoterism is the ability of a stub to fight down with either acids or bases. Iron and magnesium form insoluble precipitates in basic solution and are not amphoteric, patch zinc and chromium are amphoteric and form intricate ions in the presence of excess base. Secondly, magnesium uncomplete absorbs nor emits energy in the 200-900nm region of the spectrum. Therefore, spectrophotometer techniques cannot be...If you want to get a full essay, order it on our website: OrderCustomPaper.com
