For example, compounds obtained through reaction of chloroformate (I) with trimethylol propane and with polyethylene glycol are highly effective chelating agents suitable in hydro-metallurgy to recover valuable metals ions from aqueous solutions (Ref. 49) [Scheme 51]. 

It is quite apparent that reduction of metal in aqueous solutions had to wait for the development of electrical energy on a commercial scale. Copper was almost a unique exception. Hydro metallurgy therefore followed the developments of Michael Faraday who in 1831 provided the besis that led to Ihe dynamo and to electrical machinety. Electrical energy was available on a large scale some 40 years later. The first electrolytic reduction plant was for copped and was constructed near Swansea in 1869.
