Concentrate Or Tailings Thickening-GOLD MINING


Tailings Mineral Industry Solution

The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again the addition of polymer aids in the separation and thickening process. Thickened Tailings Storage - A discussion

Thickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry Fourie 2003 . This is normally achieved by using compression or high rate thickeners or a combination of thickeners and filter presses.

Concentrate Thickener Operation

In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its concentrate to the smelter it will have to be transported, by truck, train or ship. To illustrate

Paste Thickening: Considerations for Backfill vs. Tailings

The difference between a 10-in. slump and non-thickened tailings can be 7% to 10% solids by weight. To pinpoint a percent solids in a process like this vs. a measurable slump can be difficult. This is an important factor mostly for backfill, but also for surface disposal.

Tailings thickener retrofit, OK Tedi - Metso Outotec

The pyrite concentrate containing sulphur report to a 40m concentrate thickener, namely thickener 1. The tailings from the Pyrite recovery plant reported to two 50m Dorr Oliver conventional thickeners, both of which were to be retrofitted and upgraded. The retrofit and upgrade was to improve the settling rates of solids in the thickener.

Concentrate Dewatering and Thickening

The concentrate from the flotation section usually contains only 20 to 30% of solids as it leaves the cleaning machine and must be dewatered before being sent to the next department. The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% The website focused at tailings related

The word tailings is sometimes applied to include coarse mine waste. For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal.

High efficiency sludge thickening and dewatering process LZZG

High efficiency sludge thickening and dewatering process. published date: 10-29-2019. Thickening is a necessary part of mineral processing, and the thickener is core equipment for concentrated processing is widely used in the mineral processing and sludge dewatering industry.

Concentrate Thickeners Feedwell Replacement - AusIMM

These concentrates are subsequently dewatered by thickening and then filtration. Separate audits of the Jaguar Operation’s copper and zinc concentrate thickeners were conducted to evaluate their performance, following occasions where site personnel had identified unnecessary loss of copper and zinc concentrate to the thickener overflow.

Thickener - Mineral Processing

Thickeners are recognized as one of the most cost-effective technologies for water recovery from concentrate and tailings streams. The concentrated slurry from the thickening process is transported to the tailings dam for disposal and the recycled water is returned to the processing plant.

Five Reasons for Measuring Density in Thickening Processes

Thickening by sedimentation is applied in the mineral processing industry for product and tailings streams. recovery is required and underflow will be targeted, while in concentrate appli ions the overflow measurement is essential. Figure 1: Example of measurement lo ions at the thickener. THICKENER MEASURING POINTS


thickener will determine which of the two is prioritized. In tailings appli ions where recovery of water and minimal-sized tailings storage facilities are desired, underfl ow will be targeted to the detriment of overfl ow performance. Conversely in a typical concentrate appli ion, overfl ow clarity is an important requirement: otherwise the

Appli ion of Hydrocyclone in Gold Ore Tailings

Before the gold mine tailings are concentrated in the thickener, it will separate coarse-grained tailings that are easy to concentrate from the tailings by cyclone, and then the hydrocyclone overflow is sent to the thickener for concentration.

Paste thickening optimizes tailings disposal and water

WesTech’s solution used paste thickening technology to facilitate a second-stage tailings thickening process. Dilute slurry from the primary thickeners is pumped a distance of approximately 3 miles – to an area with adequate storage capacity for the expected 25-year life of the mine – to feed two 59-foot diameter paste thickeners at the

The Impact of Ore Body Variability on Mine Waste Tailings

Ore body variability can have a significant effect on the various elements of mine waste tailings disposal systems, including: thickening systems, tailings pump and pipeline systems, and tailings storage facilities. Ore bodies that are exploited using open-pit mining methods often consist of softer, weathered, clay-containing material near to the surface oxides , transitioning to harder rock

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
