Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

Substrate corrosion: Corrosion products can also form on the printed circuit board surface and creep across the surface. Copper and silver are both susceptible to forming sulfide corrosion products with silver being the most reactive. Copper and silver sulfide are both resistive materials and if two circuit nodes are bridged by sulfide corrosion,
