Nickel slag is produced during the smelting of metallic nickel and is a granulated slag of molten material that consists mainly of FeO-SiO 2; in addition, it is one of the largest industrial waste slag emissions. The main components of nickel slag are silica, alumina, calcium oxide, iron oxide, and so on, which are similar to those of cement.

In pyrometallurgy process involving drying, calcination and reductive smelting steps, Saprolite ore is subjected in an electric arc furnace to produce Fe–Ni alloy and Ni matte. To optimize the nickel smelting step, the slag consisted of MgO–SiO2–FeO and having a lower viscosity and high fluidity is required. In this study, a number of new slag samples with varied …
Nickel slag is a by-product of nickel smelting and was collected from a plant in China. It was crushed to particle sizes of less than 0.096 mm. The compo- ... The nickel slag was crushed with a vibratory crusher, sieved to leave particles with sizes less than 160 mesh, and the crushed nickel slag was mixed with CaO. The ingredients of the batches
The purpose of this study was to determine the compressive strength of concrete that used nickel slag as coarse aggregate. Nickel slagswere broken down with a stone crusher and filtered into coarse aggregates with the size of 1-2 cm. Concrete mix design referred to SNI 03-2834-200. The nickel slag was varied by a concentration of 0%, 25%, 50% ...

relative to otation recovery of the raw slag. Recovery of iron from nickel ash smelting (FS) slag at a nickel smelter in China, using direct reduction-magnetic separation pro-cess, has been investigated by Wang et al. [8]. In their study, calcium carbide slag was the additive and coke dust was the reductant.
Nickel smelting slag contains valuable metals including nickel and copper. Failure to recycle these metals wastes resources, and disposal of nickel slag in stockpiles results in environmental pollution. Nickel slag recycling is important, and metals can be recovered from slag by flotation. However, considering the complex forms in which valuable metals occur in …
nickel slag substitution 0%, 5%, 15%, 25% compared with normal concrete. The characteristics of the material examined are water content, sludge content, specific gravity and absorption, volume weight, abrasion with los angeles machines, and filter analysis. While the large increase in compressive strength of concrete can be ...
High-magnesium nickel slag is a hazardous waste from nickel smelting process with low pozzolanic activity. In order to improve the pozzolanic activity of high-magnesium nickel slag, this study produced a phase separation structure of high-magnesium nickel slag by activation treatment, and studied the effect of phase separation structure on the pozzolanic …
The nickel laterite in upper layer of the ore deposit, with higher content of iron (Fe) and lower content of silica (SiO 2) and magnesium (Mg) in general, belongs to the limonite type, and usually contains lower nickel of about 1%, but a certain amount of cobalt (Co), while the nickel laterite in lower layer of the ore deposit, with higher content of silica (SiO 2) and magnesium (Mg) and …
