normal size of zinc ores

Mining in Ireland

Today, Ireland is internationally renown as a major zinc-lead mining province. Over the last 40 years a string of significant base metal discoveries have been made, including the giant ore deposit at Navan (>70Mt). Zinc-lead ores are also currently exploited from two other underground operations in south-central Ireland: Lisheen and Galmoy.

Zinc - Wikipedia

In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest ...

Introduction to Mineral Processing

Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.
