Jun 23, 1992 · Oil extraction from the oil sands ore is required for valuable minerals and precious metals recovery from the clean oil sands ore tailings. Other related ore bodies containing clay/fines lenses frequently have similar mineralization of aluminum values with iron and titanium and possibly precious metal values.
In nuclear science, nuclei of heavy metals such as chromium, iron, or zinc are sometimes fired at other heavy metal targets to produce superheavy elements heavy metals are also employed as spallation targets for the production of neutrons or radioisotopes such as astatine (using lead, bismuth, thorium, or uranium in the latter case).
The disposal of tailings is a major concern for the mining industry. By Jodie Pritchard, Trina Jensen and David Welsh. The disposal of tailings is a major concern for the mining industry. Processing ore produces a waste stream, or tailings, often discharged as a slurry to a final storage area known as a Tailings Storage Facility (TSF).
Tailings water, especially heavy metal ionscontained tailings water, must be treated to the standards before discharge. Leadzinc tailings often contain a variety of toxic heavy metal ions. If entering into the human body through the food chain, it will cause serious damage to plants, animals and people''s health.
