he novel hydroelectrometallurgical technology is developed to simultaneously production of electrolytic metallic
manganese, electrolytic γ-MnO
2
and MnSO
4
∙H
2
O in one technological cycle. The united, complex technological scheme
consists of two technological lines. One of these lines is designed for: By sulfuric acid leaching of MnO containing primary
products formed by high thermal reduction of manganese oxide ores; Purification from Fe
3+
, Ni
2+
, Co
2+
and other heavy
metals cations by hydrolysis (pH
4
) and adding Na
2
S into the MnSO
4
solution; Crystallization of MnSO
4
∙H
2
O after treatment
of concentrated MnSO
4
solution in autoclave under high temperature condition; Supply of hot, autoclave outlet solution of
MnSO
4
to anodic area (anodic area is separated by anionic membrane to prevent flow of NH
4+
into anolyte) where γ-MnO
2
is deposed on the anode. The second technological line is designed for: Purification of solution prepared from MnSO4∙H2O
produced in the autoclave and technical (NH
4
)2SO
4
by (NH
4
)2S and supply of purified solution to the cathodic area of the
same reactor where metallic Mn is deposed on the cathode. In accordance with presented technological scheme, optimal
technological parameters are determined for MnSO
4
∙H
2
O and 50-55 g∙l-1 Mn
2+
containing solutions obtained by autoclave
treatment of concentrated clean solution of MnSO
4
(115 g∙l-1 Mn
2+
) produced after processing of manganese oxide ore.
The technological novelty also is exploitation of heat pump to maintain 35-380C in catholyte and 92-940C in anolyte in an
electrochemical reactor working under 20A load and divided by anionic membrane (AMI 7001S). As a cooling agent of heat
pump, R-600a (isobutane) was chosen. The evaporator of the heat pump was immersed into the catholyte and the condenser -
into the anolyte. The effectiveness of heat pump was also determined .
