    Oxidation, The following is a diagram of an electrochemical cell with zinc and copper acting as the electrod An external electric current hooked up to an electrochemical cell will make the electrons go backwards This process is called electrolysis This is used, for example, to make something gold platedActivity Series of Metals: Predicting Reactivity, Feb 28, 2020· Exploring the Activity Series Chart The activity series is a chart of metals listed in order of declining relative reactivity The top metals are more reactive than the metals on the bottom For example, both magnesium and zinc can react with hydrogen ions ,Selective precipitation of gold from aqua regia, leaving ,, Feb 25, 2010· March 6, 2010 A Ferrous Sulfate is commonly used to precipitate gold without precipitating more than traces of the platinum group metals However, this can only be done by first removing any free nitric acid still present in the aqua regia solution This is usually done by first doing a triple evaporation process on the aqua regia solutionHow silver is made, Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable Silver emerges as a byproduct of processing these metals To recover silver from zinc-bearing ores, the Parkes process is used In this method, the ore is heated until it becomes moltenMethods of Removing Heavy Metals from Industrial ,, methods precipitation is most economical and hence widely used, but many industries still use chemical procedures for treatment of effluents due to economic factors [11, 12] However due to complexing agents in wastewater, efficiency of the precipitation process ,.
