Determination Of Chemicals In A Chromite Sample

Experiment 29 Hydromet apieceurgy to Analyze a Chromite Sample: A sovereign Experiment Bret Eady, Seth Berry October 17, 2010 INTRODUCTION: The only(prenominal) ore containing chromium is chromite. Chromite is a conspiracy of bid, magnesium, chromium, and oxygen. The chromium from the chromite is used for whatever(prenominal) constructional purposes much(prenominal) as: the achievement of unblemished steel, enhancing the structural integrity of numerous metallic elements, and reducing the station at which they corrode. Sometimes the composition of chromite whitethorn vary and the branding fight in chromite may be replaced by magnesium. Also, the chromium in chromite may sometimes be replaced by aluminum and ferric ions. Hydrometallurgy is a way to pick out the different elements making up ores and isolate the metals from from each angiotensin converting enzyme other. In order for this to occur, the ore mustiness be melted stamp out into a solution. After the metals of the ore halt been dissolved, they may be detached from each other by many different processes, some of the most popular argon leaching and precipitating the metal from the solution via electrolysis or chemical means. In this experiment the team up of students must determine simply what is in chromite ensample, and also endorse the existence of all such metals that should be in the sample of chromite.

The leaching technique entrust be used and go downs create via the addition of NaOH to the leach solution. The shimmy of iron via zinc provide also be utilized. As each metal precipitate forms in the solution, it testament perplex to be separated from the remain solution and the process tell until all precipitates have been created and isolated. Next, each individual precipitate result be dissolved into an sedimentary solution and ran through a mass spectrometer. The interpretical record that the spectrometer gives of the un cognise precipitate will be compared to the known graph of these metals. The wavelength maxes will be ascertain for each of the unknowns via religious abridgment in order to determine...If you command to get a amply essay, order it on our website: Ordercustompaper.com
