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.

6. A mixture contains at least one of the ions in the silver group (Ag*, Hg²*, Pb²+). Read the following procedure and determine which ions are present. Cold 6M HCl was added to the mixture producing a white precipitate. Hot water was then added and the solution was stirred, and the supernatant decanted to isolate a white precipitate after centrifugation. Sulfuric acid was added to one portion of the supernatant and potassium chromate was added to a second portion of the supernatant, but no precipitates formed. The isolated white precipitate was mixed well with 4 drops of concentrated ammonia. The resulting solution was centrifuged. The supernatant was decanted to show the presence of a grayish-black precipitate. To the supernatant, concentrated nitric acid was added dropwise until blue litmus paper added turned red and a white precipitate was present.
