Tailings ponds and rivers continuously need to be cleaned out to increase capacity. Finding the right pump and dredging equipment can often be a complicated process. Centrifugal pumps will only pump 10-20% solids by weight. This means that most of the discharge is water and very little fly ash is coming out of the pipeline.

· 1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades .On the one hand, the tailing is considered an environmental problem …
· Press the "run" button. The bowl will start spinning. Feed slurry into the concentrator. The particles must be smaller than 2 mm. After about 30-60 minutes, stop feeding slurry into the concentrator. Reduce the process water pressure. Press the "decrease speed" button until the display shows 5 Hz.
Iron tailings: the iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings.

Centrifugal gold concentrator can be used not only for placer gold, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings, platinum, silver, mercury and native copper.
· Within limits, an enhanced gravity concentrator can treat more material and recover finer particles if it is spun faster. Falcon concentrators are able of centrifugal fields of 300g. The equipment can change this value due to the unit is equipped with a variable speed motor.
· JXSC provide full inventory of mining equipment of the manganese ore processing plant, also can do mining process flow sheet design.
liminary concentrate, or to reject tailings that contain no valu-able material at an early stage. The equipment used in this ap-plication are referred to as roughers. Roughers may produce a large amount of concentrate, permit the recovery of a very high percentage of feed gold, produce clean tailings, or produce a combination of the above.
"There are definitely TSFs that they could look to reprocess and recover copper or gold or whatever is potentially still in those tailings." Gouveia agreed, "There is great potential for reprocessing, mainly at older mines where the tailings were produced using older technologies, say, 30-50 years ago. Some of those tailings are really rich.
3. Application of Mining recovery equipment gold ore tailings concentrator Centrifugal separator is known as centrifuge or centrifugal chute. Strong centrifugal force produced by high speed spin strengthens the process of gravity separation and effectively recover the ultrafine ore particles. Nowadays, centrifugal concentrator is widely used ...
According different property of all kinds of ore tailings, Xinhai can design reasonable process and fully find the value in the tailings. [Application]: Xinhai tailings re-processing line applies to re-processing of various metal or non-metal tailings, including iron, gold, lead-zinc, copper, fluorite, wolfram, phosphate, graphite, bauxite, etc.
· Several efforts are underway to extract gold and copper from tailings. Reprocessing mine tailings may also have environmental benefits. A recent project described in Mining is a series of experiments carried out by an international group of scientists to produce approximately 30 years of passive carbonation of mine tailings within four weeks.
The Gold Centrifugal Concentrator is a brilliant gravity separation equipment widely used in the mining industry, especially for the placer gold, fine grain rock gold, and other precious minerals. 【Modes】(1) Timed automatic discharge centrifuge, customizable, higher efficiency, higher price. (2) Non-automatic discharge centrifuge, common use, in stock, manually stop working and take out ...
The TPC-800 vertical continuous cyclone centrifuge is mainly used to recover valuable mineral components with low grade (general grade less than 5%) and requiring greater yield. When the target mineral and gangue specific gravity difference is greater than 0.5%, the LXC-800 vertical continuous vortex centrifuge can effectively separate them and obtain better grade and recovery.

· Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today''s price, US$5,842/tonne, if that material could be reprocessed and an extra ...
Gold Tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, xinhai will apply the method of dry-tailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it.
However, the recovery rate is low despite high grade ores. The tailings rich in copper ore and cobalt ore used to be disposed of in tailings ponds or even discharged directly, which results in useful metal draining, simultaneously brings the enormous harm to the environment.
