Accumulation of metals in fish from lead-zinc mining areas

Although blood and liver cadmium concentrations were highest in all three species at sites near mines, within-site variability was greater and mining-related trends were less evident than for lead. Blood and liver zinc concentrations were significantly correlated only in stoneroller (r=0.46, P<0.01) and mining-related trends were not evident.

Cadmium: processing-Metalpedia

The cadmium content of the zinc concentrate is usually around 0.3% to 0.5%. An estimated 90% to 98% of the cadmium present in zinc ores is recovered in the mining and beneficiating stages of the extraction process. Figure 1 shows a schematic flow of mining and beneficiating a typical lead-zinc ore. Figure 1.

Cadmium GreenFacts

Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickel-cadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.
