Introduction In world practice sulphide ores (Romanteyev, Fedorov, & Bystrov, 2006) are a basic source for zinc manufacture. In oxidized zones of zinc-containing ore deposits zinc is found as zincite ZnO, smithsonite ZnCO 3, calamine 2ZnO·SiO 2 ·H 2 O. Zinc content in these ores makes 10-25 % (Romanteyev, Fedorov, & Bystrov, 2006; Heinrich, 1922; Zaitsev, & Margulis, 1985; Utkin, 2004
