PROPRIETARY TECHNOLOGY
DEVELOPMENT DIVISION

The Proprietary Technology Development Division (DDTP), created in 2007, alongside its renovated Technological Center, which focuses on projects in R&D to develop new technologies in TR’s strategic sectors, is the result of these activities initiated in 1971.

In 1971, TR created the Research and Development Division as a business unit to specialise in hydrometallurgical and electrochemical processes.

1974 RESEARCH
CENTER
1976, First industrial achievement...

Metalquímica del Nervión, the first hydrometallurgical plant in the world to use solvent extraction techniques to produce SHG zinc: ZINCEX® technology.

1977 MERCURY RECOVER

In 1977, the first plant was set up to recover mercury in industrial effluents from chlorine-soda plants through solvent extraction: the Mercurex process.

Its success allowed it to license and operate two more plants, one in 1978 and another in 1982, for the same industrial group (EIASA) with the same process.

1980 New ZINCEX® process reference.

In 1980, the Quimigal plant in Lisbon (Portugal) was the second reference of the ZINCEX® process for the production of zinc SHG by solvent extraction.

1987 SPENT DOMESTIC BATTERIES
RECYCLING PLANT

In 1987, in Catalonia (Spain), a plant for the recycling of used domestic batteries was started up to obtain ultra-pure zinc sulphate.

1988 COPPER SX
PROCESS

In 1988, a new plant was built in Almagrera (Andalucía, Spain). It produced for COPPER salt production (CuSO4.5H2O) through another process licencsed by TR: the Copper SX Process.

2003 MODIFIED ZINCEX® PROCESS (MZP)

In 2003 the new 150,000 t/a zinc SHG production plant under the modified ZINCEX® technology in Namibia is an improvement on the ZINCEX® technology

2010 - 2014 NEW PLANTS WITH MODIFIED ZINCEX ® TECHNOLOGY (MZP)

In 2010 in Akita (Japan) Dowa Minerals opens a new production plant of 20,000 t/a of SHG zinc with ZINCEX® modified MZP technology applied to secondary zinc materials.

In the year 2013 in Portoscuso, (Sardinia, Italy) Glencore opens a new 52,000 t/a production plant for zinc SHG from Waelz and Kivcet oxides with modified ZINCEX® technology.

In the year 2020 in Mooresboro, (North Carolina, USA) American Recycling inaugurates its new production plant of 140,000 t/a of zinc SHG from Waelz oxides with modified ZINCEX® technology and production plant under ECOLEAD® technology of 6,000 tpa of lead and 17 tpa of silver.

WORLD LEADER

Currently, more than 300,000 tpa of SHG quality zinc is produced in several plants around the world using ZINCEX® technologies, consolidating TR as a world leader in zinc production through its patented technology.
