· Ferrochrome slag is a derivative of the manufacturing of ferrochrome, an alloy of Cr (chromium) and Fe (iron) with chromium by 51–69 percent of the mass and varying proportions of Fe (iron), C (carbon), and others [ 18 – 20 ]. In 2017, the worldwide production of FC was predicted to be approximately 12 million tonnes.
Ferrochrome slag Recovery Solution. is the Ferrochrome slag. Ferrochrome slag is a byproduct from the production of ferrochrome, an essential component in stainless steel. There is a certain amount of ferrochrome alloy in the slag. Recycling the alloy in slag can not only reduce the waste of valuable resources, but also get rich returns.

South Africa is a dominant global supplier of chrome ore and ferrochrome, and the biggest exporter to China in 2017, it accounted for 73% of ...
Ferrochrome production is done by a direct carbothermic reduction of chromite on three phase submerged arc furnaces. Ferrochrome and slag are the main two products tapped off at regular intervals from tap holes at the bottom of the furnace. Cascade tapping is used to tap slag and metal through the same tap hole into the same metal vessel.
To improve total ferrochrome recovery while maintaining a highquality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers and broken down to minus 15mm material.
· Hexavalent chromium removal by ferrochromium slag The aim of this study is to demonstrate the potential of Cr(VI) generation during jigging operation applied for ferrochrome recovery from slag. The Cr(VI) concentrations of water contacted with ferrochromium slag (W/FS=10) in a closed cycle after 50 batches were found as mg/l.

Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at RD, Tata Steel to develop a flow sheet for the recovery of metal from metalslag mix generated in its charge chrome (ferrochrome with 5060% chromium) plant, Bamnipal.
· This paper provides results from the EC process optimization for Cr (VI) solutions with initial concentration 1000 mg/L of Cr (VI). Influence of pH, current intensity and NaCl concentration on the efficiency of chromium recovery, energy consumption as well as solid product composition is discussed in detail.
Ferrochrome slag is treated with lime to conduct slaglime solidsolid reaction. Chromium present in the slag reacts with lime to form mixed chromates. The reaction is conducted at 973K, soluble chromium ion was extracted with water and is subsequently separated by adsorbing fly ash based zeolite which can be recovered. The recovery of chromium metal in the slag is .
The slags produced during testwork at Mintek were either MgOAl2O3SiO2, shown in Figure 4, or MgOAl2O3SiO2CaO types. The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone).

Since its formation in 1992 it has built eleven major metal from slag recovery plants in Southern Africa capable of processing between 120 and 200tph of slag. It has also constructed a 100tph plant for Sweden, a 60tph plant for France, a 50tph plant for Romania and has supplied 10 – 35tph mobile jigging plants to clients throughout the world.
the phase area of slag shifts from dicalcium silie (larnite Са 2 SiO 4 ) area into the helenite area (2 CaO ∙ Al 2 O 3 ∙ SiO 2 Key words:lowcarbon ferrochrome, chemical composition, aluminumsiliconchrome, reductant, recovery. INTRODUCTION Multicomponent FASCh alloy is used for deoxida tion and doping of steel and for recovery of LCFC. An
During the production of high carbon ferrochrome alloy, in ferrochrome smelters, a substantial amount of slag is produced. These slags are generally disposed of in slag dumps or containment facilities causing environmental and containment problems. The slags have found limited use as aggregate for road surfacing and civil construction.
