  • How is silver extracted from its ore? Explain the process

    Silver is extracted from the argentite ore by the MacArthur and Forrest’s cyanide process The various steps involved in this process are as follows : (a) Concentration : The crushed ore is concentrated by froth floatation process (b) Treatment of ore with NaCN : The concentrated ore is treated with 04 – 06% solution of sodium cyanideCinnabar is a sulphide ore of mercury The name of the compound present in the cinnabar ore is mercury (II) sulphide Its chemical formula is HgS Mercury is a less reactive metal and it can be extracted from its sulphide ore cinnabar by heating it in air alone 1 It is first heated in the presence of surplus air (roasting process)Explain How, Mercury is Extracted from Its Sulphide OreThe sulfide ore ie, copper pyrites after the concentration by froth flotation process is roasted in a reverberatory furnace when copper pyrites are converted into a mixture of \[FeS\]\[C{{u}{2}}S\] and which, in turn, are partially oxidizedHow is copper extracted from its sulfide ore Explain class

  • Extraction of Ag from sulphide ore and removal of

    Hint:Silver is extracted from its sulphide ore by reacting with sodium cyanide which results in the formation of a complex and in the generation of photographic plate the unreacted silver bromide is washed using sodium thiosulphate solution which results in formation of another complex Complete step by step answer:The silver can be extracted from its sulphide ore by cyanide processIn the extraction of copper from its sulphide ore, the metal is formed by reduction of C u 2 O with C u 2 S The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphideIn the extraction of copper from its sulphide ore , theHighpressure oxidative acid leaching on carbonaceous sulfide ore was investigated • Optimized leaching parameters yielded over 97% copper extraction from the ore • Selective dissolution of copper over iron is achieved when free acidity is ≈10 g/L • A linear relation between log[Fe] and log[free acidity] in the PLS was established •Extraction of copper from complex carbonaceous sulfide
