Question

What is the process of leaching in case of low grade copper ores? (A) Leaching is carried out with NaOH and O2 (B) Leaching is carried out with NaCN (C) Leaching is carried out with acids in presence of H2 (D) Leaching is carried out by boiling the ore with water

Tardigrade Admin · Accepted Answer

Leaching of low grade copper ores is carried out with acid or bacteria, when copper goes into solution as Cu2+ ions. Cu2+(aq) + H2(g) → Cu(s) + 2H+(aq)

Q. What is the process of leaching in case of low grade copper ores?

Leaching is carried out with $N a O H$ and $O_{2}$

Leaching is carried out with $N a CN$

Leaching is carried out with acids in presence of $H_{2}$

Leaching is carried out by boiling the ore with water

Leaching of low grade copper ores is carried out with acid or bacteria, when copper goes into solution as $C u^{2 +}$ ions.
$C u_{(a q)}^{2 +} + H_{2 (g)} \to C u_{(s)} + 2 H_{(a q)}^{+}$
