This ultra fine highly pure zinc powder will precipitate silver or gold metal from solutions instantly and completely. Its reducing power is so great even traditional used fixer photographic solutions (‘thiosulphate’) will yield their silver content as silver sponge immediately. Ideal for precious metal recovery from e-waste. 100 g zinc powder is good to recover 330 g of silver or 201 g of gold.
In inorganic and organic chemistry zinc powder finds use as a powerful reducer, during which it oxidises to Zn (+II) which can be complexed (for separation purposes) with ammonia.
