Physical And Chemical Methods To Refine Silver Ore Mining

This silver precipitate is then collected, washed and fused to get a compact mass of silver. d. Refining : The ore containing silver needs to be refined to obtain pure silver as an end product. The silver precipitate obtained previously may contain some impurities and so the impure silver is purified by the electrolytic method

    metallurgy - metallurgy - Refining: Refining is the final procedure for removing (and often recovering as by-products) the last small amounts of impurities left after the major extraction steps have been completed. It leaves the major metallic element in a practically pure state for commercial application. The procedure is accomplished in three ways: refining by fire, by electrolytic, or by

    The platinum orebody is a thin, tabular reef covering a vast area. This enables a progressive method of mining which includes the drilling of the reef and blasting it to advance the face. It combines the increased use of industralization and trackless-mining methods in steps. Platinum mining, however, differs from gold mining in different ways

    How is Iron Refined from Ore? (with pictures)

    Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires
