Morphology

electrowinning = electrowin (semi-transparent) = electro + win + ing

The noun is formed regularly from the technical verb 'electrowin', but the specialized metallurgical sense is only partly predictable from the component parts.

Etymology

Electrowinning combines electro- meaning 'electricity', as in electricity, and winning meaning 'to win' or 'get'. So, it means using electricity to 'win' or get metal from a solution.
