silver ore chlorination research panama

SilverSilver occurs uncombined, and in ores such as argentite and chlorargyrite (horn silver) However, it is mostly extracted from lead zinc, copper, gold and copper nickel ores as a by product of mining for these metals The metal is recovered either from the ore, or during the electrolytic refining of copper.organic chemistryScheme 1 Catalytic chlorination of toluene with $\ce{Fe^3+}$ as a catalyst ortho and para products expected; (para not shown) mesomeric structures of the intermediate not shown Und higher temperatures and irradiation, halogenation takes place according to a radical chain mechanism Scheme 2 Radical chlorination of toluene under irradiation.Global Mining ResearchJan 20, 2014· Copper remains BMO Research’s preferred metal in the base metals complex

Silver

Silver metal will combine with chlorine, bromine, or iodine to form compounds As an example In this reaction, each silver atom loses one electron to a chlorine atom The silver atom becomes "one electron short" of what it usually has The one electron short silver atom is called a silver ion.
