Lindy Effect in Hydrometallurgy. [PDF]
J Sustain MetallAbstract The Lindy Effect can be formulated as: the older the technology, the longer it is expected to last. In this paper, we examine the historical aspects of hydrometallurgy through the lens of the Lindy Effect, aiming to understand why research efforts by academic and industrial groups seldom result in new commercial hydrometallurgical ...

Environmentally friendly method for regeneration of copper chloride acidic solutions used in etching of printed circuits [PDF]
E3S Web of Conferences, 2017 Etching of copper with acidic CuCl2 solution is a widely used chemical method in printed circuits production. During the process, the solution is enriched in Cu(I) ions, resulting in reduction and then loss of etching bath capacity.
