Definitions

the process according to the invention can constitute a phase occurring after the roasting operation of the ores, followed by a decantation phase of the washing solution of the roasting gases; the decanted calomel is directly introduced into the reduction reactor.
Calomel from a gas washing installation for example according to the Boliden-Norzink process, is extracted from the settling tank 1 and is introduced directly into the agitated reactor 2, maintained under vacuum.
the tank 30 is followed by a runoff column 40 with cascade or baffles 41, the bottom compartment 42 of which remains filled with mercury to serve as a hydraulic guard.
the operation is carried out in the industrial installation, the reactor having a volume equal to 1000 liters.
the stirring of the reaction medium is sufficient to keep the calomel in suspension in the reaction medium.
the mass of mercury withdrawn is equal to 119 kg.
the mercury is washed with nitric acid, according to the procedure described.
the minimum purity of the mercury thus obtained is 99.995%.
