Cuprex [Copper extraction] A process for extracting copper from sulfide ores, combining chloride leaching, electro-winning, and solvent extraction. Piloted by a consortium consisting of ICI, Nerco Minerals Company, and Tecnicas Reunidas. 

Zincex [Zinc extraction] A process for extracting zinc from pyrite cinder leachate, using organic solvents. The chloride leachate is first extracted with a secondary amine, and then with di(2-ethylhexyl)phosphoric acid to remove iron Developed by Tecnicas Reunidas, first commercialized in 1976, and now used in Spain and Portugal. 

Zinclor A development of the Zincex process which uses di-pentylpentylphosphonate (DPPP) as the extractant. Developed by Tecnicas Reunidas. 

Contact is established with Tecnicas Reunidas, Tecnical, the company that had manufactured the CESA-1 original steam receiver in the 1980 s, for a budget quotation for PS10 steam generation receiver. The company feels cdnfortable with saturated steam and gives an offer for 6.5M ... 

Although substantial work has been carried out on the recovery of lead from battery residues by electrolytic means, no system has been adopted for large-scale commercial operations. Companies such as Engitech Impianti in Italy and RSR in the USA have patents on electrolytic systems, whilst a European consortium, led by Tecnicas Reunidas in Spain, has developed the chloride-based PLACID and FLINT lead recovery processes.

This paper describes advances of the PLACID and FLINT technologies that seem to be opportune for the secondary lead industry. They have all been identified by recent and current work in the Research and Development Centre of Tecnicas Reunidas S.A. (TR) at San Fernando de Henares near Madrid in Spain.
