Residue of raw material or waste separated out during the processing of crops or mineral ores.
As used in this report, the waste from mineral beneficiation. They are usually regarded as liabilities, but under some circumstances they may be reprocessed to recover additional values.
Crushed rock from which desirable minerals have been extracted.
The remaining portion of a metal-bearing ore consisting of finely ground rock and process liquid after some or all of the metal, such as uranium, has been extracted.
The already treated gold bearing material. E.g. tailings dam or heap.
Waste products from the mining, extraction, and upgrading process.
The material that remains after all economically recoverable metals or minerals of economic interest has been removed from the ore through milling and processing.
Solid waste products derived from mineral extraction or refinement.
Fine-grained waste rock usually collected in ponds.
finely ground rock from which valuable minerals have been extracted by milling.
residue separated in the preparation of various products (as with ores)
finely ground waste rock from which valuable minerals or metals have been extracted
The material left after crushing rock that contains asbestos and removing the fibre. The extraction process does not remove all the asbestos and typically the tailings in Wittenoom contained 5% crocidolite.
Rock and other waste materials removed as impurities when waste mineral material is separated from the metal in an ore.
That portion of the ore that remains after the valuable minerals have been extracted.
Mining waste left after mechanical or chemical separation of minerals from crushed ore.
The end-product or waste of ore mining, usually piled up in close proximity of a mining area. Some will often contain some metal that can be extracted.
Waste material of little economic value separated from the economic material during processing, usually second grade or waste rock fragments derived from screening or processing of raw ores.
Tailings and chat are leftover rock created from two different milling processes. Tailings and chat both contain a high level of limestone. Chat is coarser material, while tailings have the consistency of fine sand. Tailings have been used as agricultural lime.
The fine-grained waste materials from an ore-processing operation.
Rock that remains after processing ore to remove the valuable minerals.
Ground material from a mineral processing mill after the metals and minerals of a commercial nature have been extracted.
Finely ground, generally barren rock material produced by a processing plant operating for the purpose of recovering valuable metals from ore.
portions of washed or milled ore that are regarded as too poor to be treated further, as distinguished from concentrates, or material of value
waste rock from mining operations that contains concentrations of mineral ore that are too low to make typical extraction methods economical.
The fine wet waste residue left when the concentrated mineral has been extracted from the ore.
The waste products of the processing circuit. These may still contain very small quantities of the economic mineral.
The waste material from ore after the economically recoverable metals and minerals have been extracted. Changes in the metal prices and improvements in technology can sometimes make the tailings economic to reprocess at a later stage.
material removed from a milling circuit after separation of the valuable minerals.
Tailings are a ground rock waste product that remains after the desired minerals have been removed from the ore. The most reliable way to prevent Acid Mine Drainage with tailings is to submerge the tailings under water so that they do not come into contact with oxygen. However, this must be done forever.
Particulate waste material produced during mining operations. Tailings are typically composed of the both the waste gangue minerals and also small grains of the economically important minerals which have not been recovered during mineral processing.
Waste material after the economically viable mineralisation has been removed from mined ore.
The material that remains after all metals considered economic have been removed from ore during milling.
Rock and other waste materials removed as impurities when minerals are mined and mineral deposits are processed. These materials are usually dumped on the ground or into ponds.
the rejected material from mining and screening operations
A combination of water, sand, silt and fine clay particles that is a by-product of removing bitumen from oil sand.
The finely ground residue or waste material contained in the ore remaining after floating off the mineral-bearing concentrate.
fine waste material from a mineral-processing plant, that is too poor for further treatment.
The material rejected from a mill after the valuable minerals have been recovered.
Refuse or residue material from a screening process.
The dump at a mineral processing plant; material remaining after metal is extracted from ore.
Finely ground rock of low residual value from which valuable minerals have been extracted.
(4) (a) the ground rock waste product from a mill or process plant, (b) the materials remaining after the economically valuable elements are removed from the ore. To remove the valuable elements, blasted rock typically goes through several steps of crushing and extraction or washing. The tailings usually leave the mill as a slurry of sand- or silt-sized particles in water. Tailings are commonly stored in a surface impoundment but can also be placed subaqueously in natural water bodies or backfilled into underground workings.
Finely ground rock materials left after milling is complete; distinct from the old waste dumps, todayâ€(tm)s low-grade ore stockpiles that contain rock not currently of sufficient value to warrant mining.
finely ground particles of ore deposited as waste after processing by a mill or smelter.
Waste or refuse left after milling is complete, sometimes referred to as waste dumps.
Solid waste left after uranium ore has been extracted from rock.
fine grained remains of ore once most of the valuable material has been removed in the concentration process.
Waste material from a metallurgical process after the recoverable minerals have been extracted.
In mining, waste material remaining after the valuable minerals have been extracted. Stored in piles or used as fill.
Tailings are the uneconomic remainders from mining and milling operations.
The material removed from the milling circuit after separation of the valuable metals.
Material left after opal dirt from the mine has been washed.
Material rejected from a mill after more of the recoverable valuable minerals have been extracted.
low grade minerals or waste material separated from richer mineral ore during screening or processing. a Also, refers to the lower quality streams of a flour milling process.
The material that washes out from the end of the sluice box.
Second grade or waste rock fragments derived from screening or processing or raw ores. Contaminate water quality of streams and rivers.
The waste material from a mill after the desired mineral has been extracted from the ore. Uranium tailings contain the radioactive products of uranium mixed with a large volume of non-radioactive rock, all in a finely ground form, mixed with water.
A generic term for wastes or residues of rock from mining or milling operations that typically contain high concentrations of heavy metals. Tailings are composed of sand-sized particles consolidated in large piles containing millions of tons of wastes and often covering hundreds of acres of land at mining and milling sites.
material rejected from a treatment plant after the valuable minerals have been recovered
Ground rock remaining after particular ore minerals (e.g. uranium oxides) are extracted.
Material rejected from a mine after most of the recoverable valuable minerals have been extracted
The waste material left over after mining and milling processes have been completed.
The rock waste left after most of the valuable mineral has been extracted from an ore; the part rejected in milling the ore.
Waste product from mineral processing operations
Tailings (also known as tailings pile, slickens or gangue) are the waste materials left over after removing the minerals from ore.
