three ores of zinc
Zinc Ores - chestofbooks
Zinc is not one of the most common or widely distributed metals, and never occurs native.Three of its ores are utilized, viz.:- Red zinc ore, an oxide coloured red by associated iron and manganese oxides, and containing 80 per cent. zinc; blende or black jack, a sulphide yielding 67 per cent. of the metal; and calamine or zinc-spar, a carbonate affording 52 per cent.

Zinc Ore - an overview | ScienceDirect Topics
Gold recovery from copper-zinc ores is usually higher than that obtained from either a lead-zinc or copper lead-zinc ore.This is attributed to two main factors: when selecting a reagent scheme for treatment of Cu-Zn ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme more favourable for gold flotation.

zinc processing - Ores | Britannica
zinc processing - zinc processing - Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate

Zinc Ore - an overview | ScienceDirect Topics
Zinc ores normally contain 5–15% 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 al., 2014 ). Zinc concentrate, which contains approximately 55% zinc, is roasted at a temperature approximately 800°C (1472°F).
