Hydrometallurgy

Hydro altogetheroylurgy to Analyze a Chromite Sample 10/8/09 first appearance: atomic number 24 is very important for industries in the present day. atomic number 24 is demand in hardening steel, manufacturing stainless steel, and forming many applyful alloys. Chromium is using up to plate metals, pigments, leather edgeing, catalysts, surface treatments, and refractories. Chromium is used to embarrass corrosion. The only ore that contains chromium is the mineral chromite, which is iron milligram chromium oxide. Chromite has a high melting point and a permanent crystalline structure. The purpose of this experiment is to hold the chemical field of study of an inglorious neighborhood metal ore savour to confirm that the foreigner sample is mineral chromite. The content of the unknown sample clear up stakes be determined by the use of a casing of extractive metallurgy that uses the chemistry of an aqueous settlement to nullify metals from salts, mine rals, and ores. This type of extractive metallurgy is called hydrometallurgy. First, the metal must be extracted by licentiousness the metal in a solvent, and then the metal is outback(a) from the solution. The waste materials be thrown out. Leeching, separating the waste and purifying the solution attained by leeching, and precipitating either the metal or a unalloyed compound derived from the leech solution argon necessary for this process of hydrometallurgy.

Through these processes and skills, the chemical composition of the unknown sample preempt be determined. If the unknown sample contains magnesium, iron, an d chromium then the sample is chromite. If t! he sample does not contain all of these metals, then it is not chromite. Experimental: 1) Each person should be wearing rubber eraser glasses, pants, shoes, and a shirt. 2) Mineral chromite contains magnesium, iron, and chromium. Tests will be done to determine if these are in the sample. 3) Magnesium does not absorb nor expose light energy in the 200-900nm region of the spectrum. So spectrophotometer cannot be used for...If you want to get a full essay, pronounce it on our website: OrderCustomPaper.com
