  • Why is silver extracted by the cyanide process?

    Why is silver extracted by the cyanide process?

    Answer: The cyanide ion forms many stable complexes with metals. In the case of silver it forms a complex which is water soluble (in contrast to the binary compound silver cyanide, AgCN, which is not). Many ores containing silver can be finely ground and when mixed with sodium or potassium cyani...
