Both industries of tannery and mining use the sodium sulfide and the sodium sulfhydrate for the dehairing of skins in the first case, and the flotation of minerals (copper, molybdenum, cobalt, zinc, nickel…) in the second one. Their applications include the treatment of industrial waters and the paper industry among other industrial sectors.
In Quimidroga we have sodium sulfide and sodium sulfhydrate of Spanish origin to be distributed on the national market, in North Africa (location of great part of the tannery industry) and on those markets where the mining is a relevant industry.
Both products are presented in flakes format (or in liquid solution in some cases) and in different packaging to adapt ourselves to the needs of each client. Both products are manufactured in Spain with the highest standards of quality offering an iron content lower than 10 ppm, which represents a third compared to other origins.
