The construction of a 38,000 tonnes per annum (tpa) nickel process plant for the Enterprise project was completed in 2016. The process plant, however, has been integrated with the Sentinel copper circuit in order to produce additional copper concentrate till mining activities take place at the Enterprise openpit. The environmental approval for the Enterprise project has already been granted ...
The Direct Nickel Process DNi is an atmospheric hydrometallurgical processing route designed to treat all types of nickel laterite ores, in a single flow sheet to produce a number of final saleable products. The key to the Process is the use of nitric acid as the leaching agent and the subsequent use of a patented recovery and recycling process returning +95% of the nitric acid for reuse. See ...

Nickel laterites are becoming a priority for mining companies as traditional nickel sulphide reserves are depleted. In 2010, global nickel production from laterites exceeded nickel sulphidebased ...
· 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, flatbottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...
· Thickeners are used in many mineral refining processes, including alumina, gold, nickel, mineral sands and coal washeries. In fact, most minerals go through a solid – liquid separation in a thickener at some point in their processing. Most mining process operators agree that one of their major challenges is to accurately and reliably monitor the bed level and bed mass of their thickeners ...
· This dearated slurry should help decrease the nickel particle losses that report to the thickener overflow because of the flotation effect within the the deaeration cyclones has been a slow and ongoing process, however, initial testing is encouraging. The latest test results indie a 50 % reduction ( to % solids) in nickel losses to the concentrate thickener ...
Thickener modernization improves process performance in . Thickener modernization improves process performance in Russia Installed as part of a wider modernization project at the Norilsk Nickel (Nornickel) Talnakh concentrator in Norilsk, Russia, seven radial thickeners used for middlings thickening were upgraded with Outotec High Rate Thickener (HRT) technology
The Agata Nickel Processing Project site is loed in a 4,995hectare Mineral Processing Sharing Agreement (MPSA) area loed in the adjacent municipalities of Tubay, Jabonga and Santiago in Agusan del Norte province. It is accessible by land (approximately driving time) from the provincial capital of Butuan. The project site is loed inside the contract area of the Agata DSO ...
· Nickel concentrate example. Nickel concentrate thickener (HRT, 11 m) with 2 underflow lines and UF recirculation. The existing situation included: High variation in incoming mass flow; Underflow consistency target not constantly met; Overflow dirty solids load to circulation waters; Bed pressure (level) never stabilizes ; Lot of underflow ...
Processing Nickel Ores . One Mine's Nickel Processing of Pyrrhoite, Chalcopyrite and Pentalandite Ores The ore is crushed to 5 inches in primary cone crushers, then reduced to 1/2" in short head cone crushers. The ore is then ground to 100 mesh in ball mills. Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to 200 mesh in a ball mill ...
· The key step in this process is the separation of nickel and cobalt from iron. Iron, which typically constitutes 50% of the ore, is separated by precipitation at high temperature and pressure in an acid leaching step. It is possible to achieve the selective dissolution of nickel and cobalt with less than 1 g/L iron in the leach liquor. The leach liquor is neutralized using limestone mud, and ...
Improved PAL thickener control reduces flocculant usage by 80,000 over six months. Case study: Australia Nickel Refinery upgrades their PAL thickener by installing a new SmartDiver system and integrating the output signals to their DCS to enhance their thickener control strategy.
· Installed as part of a wider modernization project at the Norilsk Nickel (Nornickel) Talnakh concentrator in Norilsk, Russia, seven radial thickeners used for middlings thickening were upgraded with Outotec High Rate Thickener (HRT) technology. The upgrade was performed to enable expansion of the crude ore processing capacity without the need to install new dewatering equipment. The .
The pyrometallurgical processes were assumed to produce nickel in metallic iron, ferronickel or nickel pig iron. Pressure acid leaching appears to offer the best economics for treating the limonite if the Neomet and DNi processes do not produce saleable byproducts. If the byproduct hematite and magnesia turn out to be saleable, particularly if the hematite can be sold for more than the ...
