Question

Give the balanced equation for the conversion of argentite into metallic silver.

Answer 1

Extraction of $Ag$ from Argentite,

$1.)$ Froth floatation.

$2)$ Leaching- $4NaCl+A{g}_{2}S⟶2WaAg{\left(CN\right)}_2+N{a}_{2}S$

$3)$ Recovery of $Ag$ - $2Na\left[Ag{\left(CN\right)}_2\right]+Zn⟶N{a}_2\left[Zn{\left(CN\right)}_4\right]+2Ag$

Hence, $Ag$ is obtained.
