Two key issues for low recovery of nickel by the above process is that metallic nickel disperses in the ore and unreduced Ni 2+ are incorporated into the fayalite structure as substitutes. Therefore, the metallic reduction roasting process followed by magnetic separation provide an effectively method for laterite ores.
The priority flotation process of copper-nickel sulfide ore usually adopts the process of "floating copper and suppressing nickel". The separation of copper and nickel is achieved by adding inhibitors of nickel sulfide minerals and high-efficiency collectors of copper. It is suitable for processing copper-nickel minerals with higher copper ...
HL is an industrial process, and ore is left for steady-state operation at ambient temperature. The process has low recovery, with ~ 68–71% nickel extraction. The heap leach operation prefers a low ratio of limonite to saprolite ore [ 12 ]. Two commercial operations were reported for HL in the literature [ 12 ]: a.

In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are …
The solid-liquid-separation processing method according to claim 1, wherein the slurry is a leach slurry obtained by applying leaching processing to a nickel oxide ore in a hydrometallurgical method for the nickel oxide ore, and a leach residue in the leach slurry is separated therefrom to obtain a leachate containing an impurity element ...
The contents of silicon dioxide and magnesium oxide in the ore are high, therefore it is considered as the typical garnierite. As discussed in the literature, reduction-roasting magnetic separation …
A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
The selective reduction method at a low-temperature process, which continued with the lateritic nickel ore's magnetic separation process, has been developed [8]. Metalization of iron is inhibited, increasing the nickel content in concentrate (magnetic particle) using additives, such as sodium sulfate, sodium carbonate, and sodium chloride …
Nickel laterites contain a significant amount of water, making drying an important aspect of processing. A rotary dryer is typically used to remove free moisture from the ore, while bound moisture is removed later via a …

The results indicated that the high‑nickel concentrates produced from direct reduction-magnetic separation process, ... With the continuous depletion of sulfide nickel ore, nickel laterite ore, accounting for as high as 72% of global land-based nickel, gradually become a preferable alternative resource for the recycling of nickel [4]. ...
Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise and surpassing conventional sulfide deposits. The efficiency of mining and processing nickel laterites is defined by …
Nickel-oxide ore treatment by pyrotechnics: Raw materials, such as lime and pulverized coal, are needed to control the ore size at 50–100 mm. Ni matte production involves reduction–sulfurization smelting. The process involves smelting of Ni–Fe in a blast furnace to produce Ni–Fe. The ore size can be controlled from 50 to 100 mm.
