Mine Tailings Sampling Technique
Sampling tailings with carefully placed drill holes from deposit surface is therefore best. Collecting cores, as preserved as possible, is preferable to other approaches, as vertical variations can be sharp, reflecting past mining or processing decisions. Sonic sampling is probably the most efficient answer to the challenge of investigating a ...

Introduction to this Special Issue on Tailings Storage
Based on research carried out at 67 tailings dams in Spain, Roberto Rodríguez et al. (Spain) conclude that: (1) tailings dams contain alternating layers with contractive and dilative geomechanical behaviors; (2) tailings saturate quickly but drain more than 10 times slower due to their high-suction capacity; and (3) over the long-term, …
50 Years of Sprawling Tailings
There were no regulations controlling tailings management or reclamation between 1975 and roughly 2010, when fluid tailings grew from 1.49 km² to 73.27 km² . New tailings regulations were implemented in 2009, stating operators had five years to reduce their fluid tailings, but our analysis shows that the fluid tailings area still grew 40 per ...
SAMPLING METHODS FOR IMPOUNDED TAILINGS
sampling. It is the most accurate method of sampling a tailing deposit, but it is usually too expensive to use. This method is used chiefly to confirm the results of auger sampling. Auger drills used for sampling tailing deposits are similar to wood augers. They obtain a sample by boring a vertical hole to the desired depth and on being withdrawn
Converting tailings dumps into mineral resources
Extraction of valuable metals from tailings dumps traditionally regarded as waste, has long been researched by metallurgists. A number of developments in mineral processing technology have combined to make the retreatment of numerous tailings dumps a profitable proposition. This is particularly the case for tailings dumps created from the ...

Mine Tailings Pump Applications
Tailings ponds are a necessary feature of all mining operations to store the residual byproduct of mineral extraction. If the ponds hit capacity, new tailings ponds need to be built or old tailings ponds need to be cleaned out. The tailings often have very low or high pH which causes a lot of difficulty for centrifugal and positive displacement ...

Mine tailings management is a long-term process that starts well before any tailings are produced (Figure 2). It can be difficult to estimate the 'typical' cost of building, operating and closing a tailings storage facility as it depends on many factors, but examples suggest up-front capital costs can be around 15 per

4.2.3 Tailings Solids. At metal mines, the amount of the ore mineral (s) extracted from an ore is relatively small, and the vast majority of mined and processed ore ends up as tailings. At modern gold mines, more than 99.999% of the originally mined and processed ore may finally become tailings.
Potentially Exploitable Reprocessing Routes for Recovering
Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …
