For more than 40 years the Proprietary Technology Development Division (DDTP) has been developing a series of in-house metal recovery technologies.
The technologies developed allow the recovery of non-ferrous metals, such as Zn, Cu, Pb, Ag, Ni, and Hg, among others, in the form of metals or of highly pure salts, using either raw materials or secondary materials.
The technologies for obtaining zinc (Modified ZINCEXTM Technology) and lead and silver (Ecolead TechnologyTM)
Both technologies stand out for their flexibility, efficiency, profitability and adaptation to different raw materials and customer requirements.
ZINCEXThe ZINCEXTM Modified Zinc Technology (MZP) is a technology for producing SHG quality or ultra-pure zinc salts.
Compared to conventional technologies (Roasting, Leaching, Electrolysis) the ZINCEXTM technology presents important technical and economic advantages among which the capacity to process a wide variety of raw materials, a lower operating cost and obtaining a higher purity product stand out.
ECOLEADECOLEADTM lead and silver recovery technology is an efficient technology for the recovery of lead and precious metals.
The integration of ECOLEADTM technology in a plant with ZINCEXTM technology is easy to implement and improves the profitability of the installation.
LIP4CATThe LIP4CATTM technology allows the recovery of zinc from the calcine in only two process stages because, being associated to the ZINCEXTM technology, it allows to perform the leaching reactions in more diluted conditions.
DATMOSThe DATMOSTM technology allows the recovery of zinc directly from metallic sulphides without the need to go through the roasting stage and without the limitation of having to use high grade metallic zinc concentrates.
