| titleOfInvention | Plant for obtaining copper sulphate pentahydrate |
| abstract | The present patent relates to a plant in a regime for the two-stage production of copper sulphate pentahydrate from oxidised copper minerals, with an average content of 20% Cu, with mineral species predominant in copper oxides. The first stage is the formation of a stock solution by agitation-leaching 45% of the mineral to be processed and subsequently concentrating to form the stock solution, and the second stage of the in-plant method is a step of saturating the solution and crystallising the copper sulphate, wherein 55% of the remaining mineral is treated during the saturation process. The crystallisation process is carried out in tanks with a coolant in the jacketed sidewalls thereof and which contain a submerged coil, refrigerated water circulating through all the coils. An interior agitation system generates a circulatory movement of the saturated solution, both vertically and horizontally, the solution undergoing controlled cooling from 80-90°C to a final temperature of 8-12°C, to form suitably sized crystals. When the saturated solution reaches a temperature close to 45°C, the initial generation of the crystals and their growth as the temperature of the solution gradually decreases can be seen. |
