costs of secondary zinc vs primary zinc

Zinc may exhibit amphoteric behaviour at pH>11, but these values are rarely found in nature. It is rapidly sorbed to secondary oxides, clay minerals and organic matter (Jenne 1968, Robinson 1981, Ure and Berrow 1982) in all but the most acid conditions (pH. 4.5). Typical Zn concentrations in river water are about 10 to 50 µg l-1 (Hem 1992).

Zinc has never been found naturally in its pure form. It can be alloyed (mixed) with a number of other metals. Zinc is brittle at ordinary temperatures but is malleable and ductile (can be beaten and drawn into a wire) when heated to 1000°C. Zinc has a relatively low melting point and is a good electrical conductor.
