The recovery increases with time and reaches maximum at 4 minutes which is an equilibrium concentration of chromium on zeolite. Further experimentation was carried out at a time of 7 minute: VII.CONCLUSIONS • Recovery of chromium from ferrochrome slag is 64% by treatment of slag with lime at 973K in solid phase.
Nov 01, 1997· Recovery of ferrochrome from slag 1255 While being attractive financially, the process also allows metal free tailings to be disposed of in a more environmentally friendly manner. Where required, a window of opportunity is also provided for the removal and disposal of potential pollutants from slag dump sites.
This study assessed chromium pollution in soils, plants, water and slag from a ferrochrome smelting plant in Gweru, Zimbabwe. Speciation of chromium in plant leaves, soil and slag samples was carried out by selective leaching of Cr (VI) using a sodium carbonate leaching procedure prior to the spectrophotometric determination of Cr (VI).
Production, Characteristics and Use of Ferrochromium Slags 173 2.1 Ferrochrome slag The temperature of the slag in tapping is 1700 °C and that of the ferrochrome 1600 °C. The smelting point of the slag has to be higher than the metal smelting point, because metal is heated up by using slag . Ferrochrome slag ore beneficiation process and device
Ferrochrome alloy recovered from slag. Most ferrochrome plants lose considerable amounts of metal in their slag and metal–slag mix. Depending on the smelting process and the age of the slag dump, the ferrochrome contents vary between 3% and 15%. Recovery of ferrochrome from mixed metal and slag through mechanized means is widely practiced and ...
Jun 19, 2020· "Ferrochrome is not the only commodity that we have successfully tested," says Refentse Molehe, process engineer at Multotec. "We have even seen improved recovery in heavy minerals below 1 mm size, alluvial chrome, manganese slag and there is potential in industrial recycling."

Granulated slag samples were collected when the industry adopted water cooled slag granulation process. Lumped slag samples were collected from the air cooled slag after material recovery. Pictures of the slag samples are shown in Fig.3.1. and 3.2. Fig. 3.1 Photographs of water cooled granulated ferrochrome slag Chapter 3
To improve total ferrochrome recovery while maintaining a high-quality 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.

es, ferrochrome alloy and slag, are tapped into ladles at 2.5 hour intervals. The ferrochrome slag production is 1.2 t / t FeCr. It is mainly granulated and the rest is air-cooled. There is an in-house special handling and metal recovery process for the air-cooled slag, where it is made into finished products. In addition to recov-
Ferrochrome slag Recovery Solution. 1.What is the Ferrochrome slag. Ferrochrome slag is a by-product 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. 2.
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 R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome (ferrochrome with 50–60% chromium) plant, Bamnipal.
