The slag is however not suitable in cement making due to the presence of high percentage of iron oxide. In many instances it is usually subjected to metal recovery before its application in steel and iron industries. Most of the materials of sludge and dusts from steel industries are recycled through sinter making in more advanced countries.

slag interface lead to an increased recovery of the precious metals from the slag. The recovery of very small particles in particular is improved by this principle. Owing to their high melting points (e.g. rhodium: 1966°C), the PGMs are not always liquid during this process. Also in this case the collector metal droplets improve the recovery ...

The process in industry, including in mining industry, would surely give negative effect such as waste polluting to the environment. Some of waste could be potentially reutilized to be a commodity with the higher economic value. Tin slag is one of them. The aim of this research was to recover the tin contained in tin slag.

NEW DELHI: Jindal Stainless Ltd (JSL) today said it has commissioned a metal recovery plant in association with Harsco Corporation at Jajpur in Odisha. The company said it will help in reducing wastage by recovering trapped metal from the slag generated during the production of ferro chrome - a key raw material for making stainless steel.

The slag products include a metallurgical powder for desulfurization of steel, hydraulic binder and slag stones for construction applications. The metals obtained are rich in Fe, Mn, V and Cr depending on the treated slag and residues. The environmental compatibility and mechanical properties of the slags have been improved after slag reduction.
