Hydrometallurgical process

Vietnam has many traditional copper casting craft villages from the North to the South, which resulting in large amounts of copper smelter slag containing Zn, Cu, Al, etc. In this study, zinc oxide and copper metal have been recovered from brass smelter slag (71.80 wt.% ZnO and 10.32 wt.% CuO) by a hydrometallurgical process.

In this article, we present a process to synthesize new material using urea modified nitrogen TiO2 nano using the hydrometallurgical method. A solution that was a mixture of TiCl4, (NH2)2CO, NH4NO3 and PVA was hydrolyzed at a „suitable‟ temperature and stirring speed and then calcined at 600 oC in 3 hours
