- •
Thermodynamic analysis of the Mn–H2O and Bi–S–Cl–H2O systems were conducted by use of Eh–pH diagrams.
- •
The electrochemical experiments of bismuthinite and pyrolusite in hydrochloric acid were carried out.
- •
Most suitable operating leach parameters of simultaneous leaching of bismuthine and pyrolusite were established.
