Tailingsfo Backfill of Tailings to Underground Workings
The backfill tailings are generally mixed on the surface with the cement in a small processing plant and then piped either down a decline, shaft or surface borehole(s) into the area of the mine that requires backfilling.

Processing LKAB
The processing of the iron ore commences once the ore has been transported to the sorting plant from the underground and surface mines. The processing takes place in three stages: sorting, concentration and pelletizing. Once the iron ore concentrate has passed the pelletizing plant, the end product small, round iron ore balls, known as iron

Paper: Underground mineral processing Gekko
The goal for underground processing is to run the plant completely remotely with minimal maintenance requirements, reducing exposure to the underground environment and, in the process, making mining safer whilst utilising stateofthe art automation practice. Challenges associated with underground processing

Appendix E: Coal Mining and Processing Methods Coal
Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flat-lying, thick, and uniform coal beds. A high-powered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floor-level conveyor system ( Figure E.2 ).

Mining Backfill Plant Resources Gold Technology
Backfill plants are used to return tailings from gold processing plants to refill underground mined volumes for environmentally safe disposal, eliminating unsightly surface dump sites. Backfill plants are designed to operate with thickened slurry product from dewatering plants to form a paste suitable for mine backfill. Main components of a Resources Backfill Plant include: PUG Mill. Medium

Case studies of simultaneous mining and mineral processing
An underground mine with many separate mining sections, for which a revised schedule was developed aiming to keep the shaft system and processing plant at capacity with the highest net value material available at any time throughout the life of mine. In the concluding section of the paper, a few brief notes are included suggesting how the strategic recommendations from enterprise optimization

Kiruna Iron Ore Mine, Sweden Mining Technology
The current main haulage level at the mine is 1,365m underground. Ore processing takes place in three concentrating plants and three pelletising plants. The mine produces more than 75,000t of iron ore a day. The processed iron ore products are transported to Narvik port via the Malmbanan and Ofotbanen mine railway lines. Completed and ongoing projects at the Kiruna mine. Although the 1,045m

Mineral processing Wikipedia
In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores. At these mines a device called a Wetherill's Magnetic Separator (invented by John Price Wetherill, 1844–1906)[1] was used. In this machine the raw ore,
