Nickel Slag an overview ScienceDirect Topics
In terms of chemical compositions, nickel slag is very siliceous that may contain up to 50–55% silica and has high magnesium content Compared with copper slag, it contains less iron, lime, and alumina The chemical composition of nickel slag is presented in Table 33 Table 33Granulated blast furnace slag should contain calcium oxide (CaO), magnesium oxide (MgO), and silicon dioxide (SiO 2), the sum of which should account for at least twothirds of the mass The remaining third contains aluminium oxide (Al 2 O 3), with small amounts of other compoundsGranulated Blast Furnace Slag an overview Granulated nickel slag is essentially an angular, black, glassy slag "sand" with most particles in the size range of minus 2 mm (No 10 sieve) to plus 0150 mm (No 100 sieve) (15) It is more porous, with lower specific gravity and higher absorption, than aircooled nickel slagUGMat Nonferrous Slags Recycled Materials Resource CenterABSTRACT In the production of base metals by smelting of sulphide ore concentrates, large amounts of iron are rejected with iron silicate slags These slags contain Ni, Cu and Co in concentrations up to several percent unitsDissolution of Valuable Metals from Nickel Smelter Slags The granulated slag was found to consist mainly of a silicate glass phase, which reflects the composition of the molten slag in the furnace Nickel occurs as free matte granules, as matte phases locked inside the glass, and in the glass phase itselfFactors affecting nickel recovery from slags produced

producing a liquid matte (up to 45% nickel) and a fluid slag Furnace matte still contains iron and sulfur, and these are oxidized in the converting step to sulfur dioxide and iron oxide by injecting air or oxygen into the molten bath Oxides form a slag, which is skimmed off Slags are processed in an electric furnace prior to discard to recover nickel Process gases are cooled, and Since 1918, The NSA has promoted the use of Blast Furnace and Steel Furnace Slag Blast Furnace slag has been called the "AllPurpose Aggregate" as it can beNational Slag Association Iron and Steel Slag Products Iron and sulfur are oxidized, and the heat that results from exothermic reactions is adequate to smelt concentrate to produce a liquid matte (up to 45% nickel) and a fluid slag Furnace matte still contains iron and sulfur that are oxidized in the converting step to sulfur dioxide and iron oxide by injecting air or oxygen into the molten bathEnvironmental Guidelines for Nickel Smelting and Refiningnickel iron granulated slag processing stainless steel Currently Indonesia mineral slag nickel slag and iron slag processing is still in its infancy almost no processing some of them used for reclamation or fill the crater The nickel iron alloy is the main raw material for stainless steel Whatever your requirements, you 'll find the perfect serviceoriented solution to match your specific nickel iron granulated slag processing stainless steel The metallic and slag phases are removed systematically from the furnace The metallic phase for further treatment, nickel enrichment and refinining and the slag for side exploitation and dumping The electric furnace slag produced comprising about 85% of the feed is granulated LARCO GMMSA The Smelting Plant
