Hydrometallurgy to Analyze a Chromite Sample INTRODUCTION: atomic fig 24 is a steel-gray, lustrous, rugged metal that is odorless, tasteless, and malleable. It is an element of great interest because of its high wearing resistance and hardness. By adding atomic number 24 to steel, the steel will indeed become highly wicked to corrosion and discoloration, frameing stainless steel. atomic number 24 is resembling used in leather processing, surface treatments, and metal coat metals. Besides its high corrosion resistance and hardness, chromium besides has a high melting point and a unchanging crystalline structure. atomic number 24 is mined as chromite (MgCr2O4). The most commons blueprint of chromite is the compound iron magnesium chromium oxide, completely in some takes, iron can be substituted with magnesium. Chromium can also be replaced with aluminum and ferric ions. The function of this experiment is to determine whether the given unknown seek contains one at a time of these metals in revision determine if the try is actually chromite. The judge 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 sicken either the metal or the pure compound derived from the bleed solution must first be performed. Leeching is separating the waste and ablutionary the solution attained by leeching. The metal should then be extracted by dissolving the metal in a subject and then removing the m etal from the solution. The rest of the wast! e 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 see into account. Magnesium does not absorb or emit muscleman in the 200 to 900 nm region of the spectrum and it will form an insoluble precipitant in a basic solution. ginger up on will also form an insoluble precipitant in a basic...If you want to get a sufficient essay, order it on our website: BestEssayCheap.com
