Refining of Crude Metal

Metallurgy could be defined as a technique by which metals can be extracted in their pure nature. Extractive metallurgy directs with the route of eradicating the valuable metals from ores and purifying the extracted metals to pure nature. In hydrometallurgy, the metal extraction’s from their ores is done using an aqueous solution. In the pyrometallurgical process, high temperatures are employed to initiate the reactions between gases, molten metals, and solids. In electrometallurgy, the technique is carried in an electrolytic cell.

0.683 grams of iron mineral dissolves with acid. Fe2+ is titrated with Ce(SO4)2 solution. Calculate the percentage of 38.5 mL of 0.161 M titrant consumed in the titration (Fe: 56 g/mol). 25.4150.82C.76,23D.32,45
An ore containing magnetite, Fe3O4, was analysed by dissolving a 4.9 g sample in concentrated HCl, giving a mixture of Fe2+ and Fe3+. After adding HNO3 to oxidize any Fe2+ to Fe3+, the resulting solution was diluted with water and the Fe3+ precipitated as Fe(OH)3 by adding NH3. After filtering and rinsing, the residue was ignited, giving 2.8 g of pure Fe2O3. Calculate the %w/w Fe3O4 in the sample (Fe3O4 =231.54 g/mol, Fe2O3 = 159.69 g/mol)

Then, for testing the iodide test, the acidified solution of sodium iodide (NaI) reacts with Fe(NO3)3 , the following reaction takes place and showed FeI3 and NaNO3 are formed as products. The formed FeI3 is dark yellow to brown in colour. 3NaI + Fe(NO3)3 → FeI3 + 3NaNO3 After the addition of dichloro-methane the colour still remains the same. The equation is as follows: 2FeI3 + 3CH2Cl2 → 3CH2I2 + 2FeCl3 All the above reactions involved in the test are double displacement reactions. So, the above test is positive (formation of dark yellow to brown color solution), it indicates the presence of iodide ion in the solution. Question : Explain more about this experiment results.
