Direct Nickel Process – Breakthrough Technology Dr Fiona McCarthy and Graham Brock Australian Minerals Research Centre, PO Box 7229, Karawara, Western Australia 6152 Email: Corresponding Author [email protected] Abstract. Direct Nickel (DNi), in partnership with PT ANTAM, is commercializing its technology, which leaches the full nickel laterite profile in nitric acid. This .

The segregation process as applied to nickel laterite ores involves the formation of gaseous nickel and iron chlorides which are subsequently reduced to form ferronickel on the surface of a solid carbon reductant. A fundamental study of the process has been carried out .

A typical nickel laterite profile can be divided into four zones (Figure 1). The weathering effect progressively increases from bottom to top with the magnesium content of the ore decreasing and the iron content increasing with increased weathering (Elias, 1981; Burger, 1996). Saprolite. The lowest layer reflects early stages of weathering of ...

26/05/2011 · The United States has no active nickel mines or nickel reserves. Ni-Co laterite deposits provide one of two major natural sources of nickel and cobalt. The economic importance of this deposit type expands in direct relation with industrialization of developing countries. Until now, the world nickel supply has been predominantly from sulfide ...

In late 2017, the Company began a programme of project assessments for nickel-cobalt, focussing on lateritic style mineralisation. Australia is well endowed with nickel laterite regions that earlier explorers and developers had mostly defined nickel resources and reserves with cobalt being the by-product of this resource definition.

Where are the world's top nickel deposits located? As some of you may know, 65 percent of nickel used in the Western World is used to produce stainless steel. There's money to be made in the silvery-white metal as it plays a significant role in the preparation of alloys.

The Ravensthorpe Nickel Operation (Australia) was sold by BHP Billiton to First Quantum Minerals Australia on 9 December 2009. Due to reduced profitability prospects, decreasing scope of the nickel market, and a gap between projected capital expenditure and production volumes, BHP Billiton decided to sell the operation for $340m.

The pper examines the pressure acid leaching processes characteristics of three West Australian nickel-cobalt laterite projects, Murrin Murrin, Cawse and Bulong, and compares them with the only ...

Regolith and Landscapes in Eastern Australia L. Foster & R.A. Eggleton. The Marlborough nickel laterite deposits. 34 discontinuity. Dyke (DYK) - Dykes consist of dolerite, micro-gabbro and dunite.Dykes vary in width from 30 cm to 5 m.

Direct Nickel Ltd. successfully tested its DNi laterite leaching process in a 1-t/d pilot plant, a section of which is pictured above. The plant used feed from PT Antam's Buli nickel mine in Indonesia, where Direct Nickel is considering building a 10,000-20,000 t/y commercial-scale plant.

Greenvale Nickel Mine (Greenvale Laterite Mine), Greenvale, Charters Towers Region, Queensland, Australia : Nickel laterite 376 KM SSE of Conjuboy Homestead, 5KM W of Greenvale Township, 190 km WNW of Townsville.

Nickel Laterites in SE Asia Presented by: Mick Elias Principal Consultant CSA Global BALI 2013 East Asia: Geology, Exploration Technologies and Mines May 27, 2013 • What are nickel laterites and how do they form? • Range of deposit types • Global distribution of lateritic nickel resources • Exploration and resource delineation • Processing options for nickel laterite ores ...

its -owned Kalgoorlie Nickel Project (KNP or the Project) located immediately north of Kalgoorlie in the Eastern Goldfields mining district of Western Australia • The KNP, with a 2012 JORC-compliant Mineral Resource of 796Mt grading 0.70% nickel and 0.048% cobalt, is one of the largest undeveloped nickel laterite deposits in the world

Nickel laterite deposits – geological overview, resources and exploitation M. Elias Mick Elias Associates, CSA Australia Pty Ltd, PO Box 139, Burswood WA 6100, Australia

20/06/2018 · Laterite nickel versus sulphide nickel. Manufacturers have two potential main sources: nickel laterite and nickel sulphide deposits. Nickel laterite deposits are more common and comprise 60% of the world's nickel resources. This form of nickel covers a larger area, is usually near surface, and is therefore amenable to a less costly open pit ...

The laterite is composed of two separate distinct mineralized zones characterized by a nickel silicate zone and a residual iron oxide–nickel phase (Fig. 8.3). The silicate zone contains Ni concentrations reaching up to 1.5 wt.% with lateral and vertical variation. The silicate zone is composed of olivine and serpentine at the base of the horizon and is gradually replaced by secondary ...

NICO YOUNG COBALT-NICKEL LATERITE: UPDATED MINERAL RESOURCE HIGHLIGHTS ... Ltd ("Geostat"), have completed a re-assessment of the owned Young Cobalt-Nickel project in New South Wales, Australia "Nico Young" or "the Project"). The focus of these initial efforts is an update of the Nico Young mineral resource by Geostat, who had earlier prepared the previous resource estimate ...

In 2013 world production of nickel metal was 2.5 Mtonne, with Indonesia, Phiippines, Russia, Canada and Australia the dominant producers. Australia's production was 240,000 tonne nickel metal mainly from sulphide and laterite deposts in Western Australia.

Australia's nickel production is dominated by komatiite deposits (82%) that are associated with Archean (>2 500 million years old) greenstone sequences, whereas the majority of Australia's nickel resources are located in laterite deposits (69%). This is in contrast to the world situation where komatiite deposits (18%) provide the fourth largest ...

Laterite-hosted nickel deposits form by the weathering of ultramafic rocks and are a near-surface phenomenon related to tropical climates. Although Australia holds large resources of lateritic nickel, very large deposits of this type also occur in Indonesia, New .
