Production chain (continued) Saline effluent disposal process at the tank house. Saline effluent is a by-product of nickel refining operations that has to be disposed of. In Monchegorsk, the process is designed in the form of a closed cycle. The steam and condensate resulting from evaporation are then reused in the tank-house to heat …

How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...
The West Musgrave copper-nickel mine is located 1,300km northeast of Perth in Western Australia and 1,400km northwest of Adelaide. It is situated 500km west of Uluru and 30km south of the Jameson (Mantamaru) community. ... The concentrate will undergo thickening, filtration and storage processes.
Conventional Nickel and Copper Flotation underpin the Metallurgical Processes in the 2024 PEA. Over the life of mine, the Samapleu-Grata project will produce an annual average of 36,627 tonnes of a 26% copper concentrate and 55,119 tonnes of a 13% nickel concentrate through a process plant with a capacity of 5.475 Mtpa.
After crushing and milling steps the slurry of copper go to the flotation process in order to separate the copper concentrate from the copper tailings. The last step of the process before the copper concentrate filtration is the thickening of the copper concentrate slurry by the high rate thickener. Case Study on Copper Concentrate Filtration
The nickel concentrate graded 13.0% at a recovery of 80% and the copper concentrate graded 25.5% at a recovery of 77%. Comminution testwork was completed consistent with that completed on the Andover Deposit. ... Nickel cleaner-scavenger concentrate also reports to the nickel concentrate thickening and filtration area, while …
The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The inlet …
Iron Ore Concentrate Filtration. We have different types of iron ore concentrate like magnetite, hematite, limonite etc. This iron ore concentrate filtration case study is for the filtration of magnetite iron ore …
The highest values of solid phase compaction were calculated along with evaluation of overflow turbidity in the course of fractional thickening. The nickel concentrate initial sample was taken for determination of nickel, copper and sulfur percentages as well as composition of its specific size-grades by X-ray spectrum analysis.
Introduction: Mineral thickeners are recognized as the most cost-effective equipment 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.
The plant consists of run of mine (ROM) ore storage; single stage jaw crushing and crushed ore stockpile; primary grinding using a SAG mill; flotation and concentrate regrinding; …
cells, thickening tanks, filters, and magnetic separators. Three sulfide concentrates are pro-duced: copper, nickel concentrate containing some copper, and iron. The copper concentrate is sent to the copper smelting furnace, the nickel concentrate to the smelter roasting fur-naces, and the iron concentrate to the iron-ore recovery process.
The bubbles break and solids from the froth solution settle at the bottom of the tank. The solids are then filtered to remove excess water, which can be reused in processing additional batches of sulfide ore. The final product of the thickening stage is a combination of 30% copper and other metals; this copper concentrate is then sent to the ...
The plant design incorporates conventional flotation, magnetic separation, and concentrate thickening and filtration to produce nickel concentrate. The plan is for an expansion in …
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% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...

Nickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal with a relatively high melting point and excellent corrosion resistance. Nickel is commonly found in the Earth's crust, but it is typically …
(TSF). The nickel cleaner circuit doses promoter at a lower rate to upgrade the grade of the rougher concentrate. Nickel cleaner concentrate reports to the nickel concentrate thickening and filtration area. Nickel cleaner tailings report to the nickel re-grind and cleaner-scavenger circuit.
The Savannah Nickel Plant produces a bulk Nickel Concentrate via single-stage crushing, closed circuit SAG Mill, flash and non-sequential flotation, thickening and press filtration dewatering. Tailings are also re-processed into backfill paste via disc filtration and binder agent batching prior to down-hole reticulation. SCOPE:
Most of the world's minerals pass through solid-liquid separation in a thickener at some point in their processing. Thickeners are used to either: concentrate mineral slurries prior to extraction of commodities. create a liquid free of solids for subsequent extraction of dissolved metals. wash contaminants from mineral solids.
Key Benefits. Reduced costs. Maximised soluble metal recovery. Increased process throughput. After-market service.
The key processing stages include crushing, milling, flotation, thickening, filtration, and end product packaging. The concentrator has two processing lines. Copper and iron ore concentrates are sold via third parties, while gold concentrates are …
How much you feed a thickener and how/where you feed it will determine how well slurry or concentrate settles it it as well as the level of ease or difficulty you will have at obtaining a good underflow density and overflow clarity. By using the head assay of the concentrator, and the metallurgical test results that determined the percentage of ...
