Hydrometallurgy to Analyze a Chromite Sample INTRODUCTION: atomic effect 24 is a steel-gray, lustrous, rugged metal that is odorless, tasteless, and malleable. It is an element of nifty interest because of its high wearing resistance and hardness. By adding chromium to steel, the steel will indeed become highly large-minded to corrosion and discoloration, frameing stainless steel. atomic number 24 is too used in leather processing, surface treatments, and metal metal plating metals. Besides its high corrosion resistance and hardness, chromium also has a high melting point and a indestructible crystalline structure. atomic number 24 is mined as chromite (MgCr2O4). The most park go of chromite is the compound iron magnesium chromium oxide, but in some takes, iron can be substituted with magnesium. Chromium can also be replaced with aluminum and ferric ions. The bit of this experiment is to determine whether the given unknown seek contains respectively of t hese metals in revision determine if the archetype is actually chromite. The examine will be tested for each mineral by an extractive metallurgy that uses the chemistry of an aqueous solution to remove metals from salts, minerals, and ores, which is called hydrometallurgy.

Before extracting the metal, bloodsuckering and diminish either the metal or the pure compound derived from the sponger solution must first be performed. Leeching is separating the waste and purging the solution attained by leeching. The metal should then be extracted by dissolving the metal in a parentage and then removing the metal from t he solution. The rest of the waste materials! should then be removed and discarded. In order to determine whether the metal sample includes the elements contained in chromite, the basic properties of magnesium, iron, and chromium must be interpreted into account. Magnesium does not absorb or emit muscular tissue in the 200 to 900 nm region of the spectrum and it will form an insoluble overhasty in a basic solution. crusade on will also form an insoluble precipitant in a basic...If you want to get a adequate essay, order it on our website: BestEssayCheap.com
