The important minerals in zinc ores are sphalerite (ZnS), zincite (ZnO), franklinite [ZnO (Fe,Mn)2 O 3 ], calamine [Zn 2 (OH) 2 SiO 3 ], and smithstone (ZnCO 3 ). Zinc ores normally contain 515% zinc. Approximately 80% of zinc mines are underground mined, 8% are mined from open pits, and the remainder are a combination of both ores ( Ray et ...

The concentration of zinc, lead and silver in the mineralized rock extracted from the Jayula and Tesorera pits in the San Cristóbal mine is very low; it is therefore necessary to have the material undergo a process designed to increase the content of these elements and thus obtain products with a commercial value. In this sense, the concentration plant was designed to obtain two enriched ...

With most ores containing lead and zinc sulphides, the production of a separate lead concentrate for shipment to the lead smelter, and of a separate zinc concentrate to ship to the zinc smelter, makes for a profitable operation. It only gravity concentration or bulk flotation were used the ore would probably prove unprofitable to treat.

An important first step entails ensuring the sphalerite surface is not activated with dissolved metal ions, which then makes the sphalerite nonfloatable. The established leadzinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression).
