Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of .
Nickel laterite ores have high moisture contents (typically up to 40%) as well as chemically bonded water in the hydroxide form. Dehydration as a minimum, and some prereduction of the ore in a rotary kiln is used to optimize the utilization of electric energy for smelting operations in the conventional submergedarc furnace process. During the dehydration of the ore, a large fraction of fines is generated.
Historically, most nickel production has been derived from sulfide ores with laterite ores providing only a modest source. In terms of known nickel resources, approximately 60% is found in laterites while 40% is contained in sulfides  – the reverse of production.

the storage and recycle of plant process water. However, there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper, and precious metals, and consideration should be given to further processing for their recovery.
The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or. magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe)9S8].
May 13, 2019· Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. The next process in nickel smelting is refining the liquid matte, which is typically done with one of two processes. With fluid bed roasting, sulfides are added to the liquid matte and the two are roasted together,...
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Nickel Processing 15 is organized between 13 May and 14 May 2015.. The venue of the Symposium has been decided on as St Michaels Hotel in Falmouth, UK..
