Abstract
Improvements in the manufacturing process of sodium sulfide, characterized in that a carbonaceous product is finely ground, free of iron salts and poor or ash-free, the carbonaceous product then being dosed in an amount close to the theoretical amount depending on the amount of sulphate sodium, after which both products are intimately mixed until a homogenous mixture is obtained, which is introduced, for its reaction, in an oven and treated at a temperature of the order of 1100ºc in a minimum oxidant atmosphere, after which the molten product of reaction, in molds to the effect, with separation of the slags, from where, once cooled it is extracted, it is rudely parted and it is packaged.
