Chrome is a critical industrial metal known for its hardness and resistance to corrosion, widely used in stainless steel production, nonferrous alloys, pigments, and leather processing. The beneficiation process of chrome typically involves four stages: ore preparation, coarse chrome beneficiation, fine chrome beneficiation, and water recovery.
Ladle furnace (LF) slag plays an important role in modern steel making in terms of quality and productivity. The major challenge of using LF slag is its dusting problem. The polymorphic transformation of β-dicalcium silicate (monoclinic) to γ-dicalcium silicate (Orthorhombic) at about 450 °C is the leading cause of its disintegration. …
Lump Iron and Steel Slag Beneficiation Applications. Iron and steel factories produce waste steel slag, which depending on their production methods and volumes that contains high rate iron. Since these steel slags contain high amounts of unwanted minerals, it is not possible to reuse them in this way.
Introduce Stainless Steel Slag Processing IMAG2258. The solution is designed according to the nature characteristics of nickel-iron slag, using the concept of recovering coarse particles before fine particles, which avoids the damage to the crusher caused by large pieces of nickel-iron alloy that cannot be crushed.

In case of SS slag and low carbon (LC) FeCr slag a wet high intensity magnetic separation can up-concentrate Cr in the SS slag (fraction <150 µm) from 2.3 wt.% to almost 9 wt.% with a yield of 7 ...
There are two type methods for nickel enrichment plants. Depending on the mineralogy of nickel ores, high magnetic intensity magnetic separation and hydrometallurgical methods can be used in the pre-enrichment stage. In the final stage, the desired nickel grade can be reached by leaching method under high pressure and temperature.
Spinel phase is considered to be the optimal phase for stabilization of chromium in stainless steel slag. In order to restrain chromium leaching from slag for the effective environmental protection, Al 2 O 3 was utilized for the modification treatment, and the effects on the enrichment and stabilization of chromium were investigated. The …
