removing from the zinc bath [7]. Although hard zinc is rich in zinc it can not be reused in the galvanization processes. There are several methods for hard zinc processing [8,9]. Bottom dross processing in order to ZnO powder production in Slovakia is realized in firm SlovZink, a.s. Košeca [10].

Spangles produced in this process have a snowflake appearance. Factors that affect spangle size are: Zinc chemistry ; Cooling rate; Smoothness of the substrate; Impurities; Alloying element; Spangle sizes on galvanized steel sheets are classified as regular, minimized or zero spangle.

protection provided by zinc is nearly proportional to the thickness of zinc. The rate of zinc corrosion is increased in environments with high moisture from humidity or condensation. Because industrial products must endure many years of service life, a generous layer of zinc is further protected by coatings such as chromate and top coat sealers.

Lead and zinc are traditionally mined together, although the concentrates produced from these mixed ores are often processed separately to produce refined lead metal (the lead blast furnace process) and refined zinc metal (the electrolytic zinc process).

Brasses containing between 32 and 39% zinc have a two phase structure, composed of alpha and beta phases. Yellow brasses are in this intermediate category of brasses. Brasses containing more than 39% zinc, such as Muntz metal, have a predominantly beta structure. The beta phase is harder than the alpha phase.
