Alex Newth Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which ...

world's accessible nickel reserves are oxidic ores called "laterite" (Sudol, 2005), and are the result of chemical weathering and supergene enrichment of mafic/ultramafic rocks. They vary greatly in depth, nickel grade and mineralogy (Dalvi et al., 2004). The lower layers are called "saprolite" and have nickel contents from 1.8 to 3 wt-%, relatively low iron contents
The wet smelting plant for nickel oxide ore (20) comprises two or more series of the processing facilities, each processing facility including a step operating facility, a utility feed facility (8a), (8b), a hydrogen sulfide feed facility (10a), (10b), a flocculant feed facility (14a), (14b), and a neutralizer feed facility (12a), (12b) and is featured in that connecting installations are ...
12-07-2021· Comprised an open-cut nickel mine and a pyrometallurgical plant, Koniambo Nickel Project is located in the North Province of New Caledonia and was officially inaugurated in November 2014. It is one of the world's biggest and highest-grade undeveloped nickel laterite deposits.
Our Operation. PT Vale produces nickel in matte, an intermediate product, from lateritic ores at our integrated mining and processing facilities near Sorowako on the island of Sulawesi. Our entire production is sold in US dollars under long-term contracts for refining in Japan. Since the establishment in July 1968, PT Vale has been operating ...
Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very different ores—lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weathering will, with time, extract and deposit it in layers at varying depths below the surface. Lateritic ores are excavated using large
NICKEL SULFIDE VERSUS LATERITE : THE HARD SUSTAINABILITY CHALLENGE REMAINS ... through conventional mining, smelting and refining, compared to laterite ores which require intensive hydrometallurgical processing ... from all Ni laterite projects (especially HPAL plants).
Modelling of Nickel Laterite Smelting to Ferronickel Douglas R Swinbourne School of Civil, Environmental and Chemical Engineering, RMIT University, 124 Latrobe Street, Melbourne 3000, Australia. Keywords: nickel laterite smelting, ferronickel Most nickel is produced as the metal, but about a third of the world's new nickel is ferronickel.
01-05-1987· Nowadays, there are four ferro-nickel smelting plants using laterite in Japan. Table 4 shows their equipment and capacity. The Hachinohe Works of the Pacific Metals Co. is one of those using the rotary kiln - electric furnace process and has the largest electric furnace for ferro-nickel smelting, with an actual load of 36,500 kW, an outer diameter of 18 m and an electrode diameter of 2 m.

Lateritic Nickel Ore Processing. While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below.
a smelter plant at South Konawe. The purpose is to increase the value-added of lateritic nickel ore that have been sold as raw materials. According to Astuti et al. (2012). The laterite nickel ore is usually found in a tropical or sub-tropical area containing high Fe and Mg-weathered ultramafic rocks. The

The Direct Nickel Process can treat the full laterite profile, not just the saprolite material favoured by the smelting route or the limonite favoured by high pressure acid leaching plants It can treat the lower grade resources remaining after smelters have taken their pick of the Test Plant achieving the full flow sheet.

Example 2 - 120 kW test . A 120 kW DC-arc furnace was used for the processing of laterite calcine blends, with the objective being the study of the smelting behaviour of materials with SiO 2 /MgO ratios ranging from 1.2 to 3.0. The smelting of laterite types having a range of Fe contents from 15 to 20% was tested at the same time. A part of the test was devoted to the smelting of lateritic ...
concentrates of nickel and cobalt to produce both refined nickel and cobalt. The process was tested in an integrated pilot plant campaign in 1996. 1 More recently, CESL has adapted the process to treat lateritic ores. Acid pressure leaching of laterite ores is quite
