Apr 22, 2019· Leaching is the process in which the ore is concentrated by chemical reaction with a suitable reagent which dissolves the ore but not the impurities,, bauxite is leached with a hot concentrated solution of NaOH which dissolves aluminium while other oxides (Fe 2 O 3, TiO 2, SiO 2), remain undissolved and noble metals (Ag and Au) are leached ...
Silver is used also in catalysis of chemical reactions. The compounds of silver are used in Xrays and photographic films. Silver compounds such as dilute silver nitrate solutions and others are used as micro biocides and disinfectants as it is used to treat medical instruments, catheters, used on bandages and wounddressings.

Sol: Gold and silver ores are concentrated by leaching. In this method, we treat the ore with a suitable reagent in which ore is soluble but impurities do not. Thus, impurities are removed by filtration. Among galena, copper pyrites, cinnabar and Argentine, Argentite being silver ore is concentrated by chemical leaching method.
Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...
