    Processing of Nickel Laterite Ores on the Rise

    The Move to Nickel LateritesLateritic Nickel Ore ProcessingConclusionSulfides have long supplied the bulk of the global appetite for nickel. But dwindling resources combined with the need to mine at greater (and subsequently less economic) depths to obtain sulfide ores has many miners looking at nickel laterites. Additionally, nickel is expected to see growth in demand as developing economies spur a greater need for stainless steel. Similarly, demand is expected to grow as a result of nickel’s use in lit在feeco上查看更多信息

    Nickel processing Extraction and refining Britannica

    Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

Nickel Mining and Processing: Everything you Need to Know

The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899

Processing. After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then smelted (in a furnace) to produce a sulfide ‘matte

Hydrometallurgical treatment, by direct acid leaching of the ore at temperatures above 240°C, is however an alternative treatment option for several new projects. The basic steps in the process are as follows: There are a number of possible variations to the above basic flowsheet. Other metals, such as copper and cobalt, can also be recovered by HPAL. On the other hand, the HPAL process is

After the grinding process, the fine ore is mixed with fuel oil reductant and fed into 12 multi-hearth furnaces where the nickel and cobalt compounds are reduced at very high temperatures to reactive metals. The hot ore is cooled then leached in an ammonium carbonate solution and the nickel and cobalt dissolve into soluble amines. The nickel and cobalt amines are separated from the waste
