The non magnetic ore is sent to a series of rougher, cleaner flotation cells, and produces a 31% copper concentrate. The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate.
From Table 2, it is found that the nickel concentrate of each ore has increased the nickel content by 10 to 30%, compared with that of the raw ore, and as for a saprolite ore with low nickel content, nickel recovery rate is about 60%. Example 2 . Nickel concentration processing of a saprolite ore was carried out according to a flow-sheet of FIG. 3.
In many mining operations ore is crushed and wet milled to liberate the valuable mineral. This slurry is concentrated by flotation and then filtered to form a dry mineral concentrate that is shipped to refineries to produce metallic products. iron, lead, manganese, nickel and zinc concentrates. Shipment / Storage / Risk factors. The above
Concentration plant with a nominal capacity 11 Mtpa of ore. Nickel concentrate transported by road to Leinster nickel operations for drying and on-shipping. Combined production numbers are reported under Nickel West Operation
Hydromet Technology. Hydrometallurgy, or “hydromet” for short, is a metal processing technology that uses a chemical process combining water, oxygen or other substances in a pressurized or other vessel to dissolve a metal from its ore, concentrate or an intermediate product (such as matte). The nickel industry worldwide has traditionally
Concentrate. Operations; Products; Concentrate; Processed ore becomes concentrates. A large part of the ore mined is complex ore comprising several different metals. The ore is crushed to form several mineral concentrates which can then be processed into pure metals in our smelters. Production. We produce copper, lead, nickel and zinc
Aug 09, 2019· Low-grade disseminated sulphide ore is mined from Mt Keith, a large open-pit operation. The ore is crushed and processed on-site to produce nickel concentrate. High-grade nickel sulphide ore is mined at Cliffs and Leinster underground mines and Rocky’s Reward open-pit mine. The ore is processed through a concentrator and dryer at Leinster.
Nickel concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas.
Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte. Nickel (Ni) is a silvery-white, hard metal.
In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.
Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore. Because it is easier to recovery cooper from the nickel concentrate. The process has a best advantage-get the copper concentrate that has a low nickel rate directly. Cases
Apr 15, 2020· nickel concentrate can be obtained after the beneﬁciation process before smelting. Nickel ores are usually divided into three types: Nickel sulﬁde, nickel oxide, and nickel arsenide. Nickel arsenide As a nickel ore, it was discovered by Garnier in New Caledonia in 1863,
May 01, 2014· The samples of nickel ore and nickel concentrate were collected from the Hongqiling nickel deposit in Jilin province. The raw materials were crushed and passed through a 2.0‐mm sieve. The rough samples were then ground for 48 hr in a high‐alumina ball mill to a final size of < 0.074 mm. Homogeneity of the samples was tested by X‐ray
Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH …
Mar 24, 2021· The raw nickel ore is always companied by clay and impurities. The washing ore process can remove clay and impurities before crushing and beneficiation operations, which improves operating efficiency and helps to obtain high-grade nickel concentrate. The ore washing equipment used in laterite ore mainly is a coarse and fine material screw washer.
The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. A road network links our mining complex to a landing strip located at Donaldson, and to warehouses and seaport facilities located at Deception Bay.
Nickel + Cobalt 0.5 1 Selenium 0.03 15 Zinc 3 0.3 It is to be understood that, if an impurity is penalized, any corresponding metal value is not paid for presenting a “double” opportunity to the concentrate provider. For example, the penalty for excessive nickel may not appear to be high, but the lost nickel value itself can be appreciable.
Sep 16, 2011· The composite flotation tests were conducted at a moderately coarse grind size of 106 µm (P80) using a conventional concentrate processing technique for nickel sulphide ore.
Jul 06, 2020· The purpose of MHP agglomeration is the hydro-pyro integration, by which the nickel concentrate (MHP) can be used in ferronickel smelters through pellets with acceptable granulometry to be processed in furnaces. Complete processing route, from lateritic ore to nickel alloy, has advantages obtaining MHP as a nickel intermediate product.

Approximately 1.3 million tonnes of ore is treated annually at the concentrator resulting in more than 39,000 tonnes of nickel-in-concentrate annually. Mill capacity is 3,000 tonnes per day. The nickel concentrate is trucked 100 km to the Deception Bay seaport facilities, where it is stored in a dome warehouse until shipped to Quebec City via

Sep 06, 2019· The parts enriched with nickel, cobalt, and often also iron, are mixed with metallurgical coke. This coke is obtained from bituminous coal in ovens with an oxygen-free atmosphere, removing the volatile content and obtaining a porous coal suitable for these metallurgical treatments. The ore is mixed with calcium oxide and silica, producing a slag.
A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This
The ore is processed through a concentrator and dryer at Leinster. Nickel West’s concentrator plant in Kambalda processes ore and concentrate purchased from third parties. The three streams of nickel concentrate come together at the Nickel West Kalgoorlie smelter, a vital part of our integrated business.
