Tailings are created as mined ore is processed into particles of fine sand through crushing, grinding and milling. Mined ore is moved to the milling circuit where the rock is reduced into sand and silt sized particles and then mixed with water and moved as slurry through the gold

Gold and Tailings: The Standard Mill at Bodie, California

The process of treating gold ore to extract gold (and silver) and, therefore, produce bullion is called milling. The building housing the process is called a mill. The finely pulverized material that is rejected from the mill after the gold has been extracted is called tailings.

Reprocessing Gold Tailings by Gravity Methods

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods. These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results, but the concentrates have been examined in polished sections for mineragraphic analysis.

A conventional tailings facility, designed to store water, can provide a mining operation with a buffer (e.g. storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water. May not be practical for some ore

MORE ON TAILINGS

Specimen gold or gold still in the host rock comes in many forms and I have found some very impressive crystalline gold on quartz over the years in the old throw away piles or dumps. In the old days ore was sorted by hand and if you couldn't see gold you threw it away, but often there was gold within the rock that was not visible.

Tailingsfo What are tailings?

Tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product. Ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristics.

Mine Tailings

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and

Mining involves the extraction of ore—the rock containing economically recoverable amounts of desired metals—from the host rock. To access the ore deposits, waste rock must be removed and stored in waste rock dumps and, after processing, mine tailings may be produced and stored in engineered tailings storage facilities (TSFs).
