·A new way to efficient utilization of eggshell waste As green dephosphorization agent and accelerator for reduction roasting of high phosphorus oolitic iron ore Reduction roasting of high phosphorus oolitic iron ore HPOIO requires the addition of expensive alkali metal compounds to enhance dephosphorization In this paper the eggshell
·The extent to which iron ore tailings are produced at different washing plants in India from iron ore mining activities is presented in Table 1 From the foregoing it is evident that large quantities of iron ore slimes are annually produced in India and the iron content of such waste streams varies between 52 and % Fe
·Utilization Potential of Iron Ore Tailing Waste in Various Applications S R Bharath N Lavanya H B Bharath Kumar R K Chaitra and Rahul Dandautiya Abstract Iron ore tailing IOT is the wastes generated during the salutariness process of iron ore concentration These wastes are abundant in quantity which can be utilized in many ways
·Iron rich industrial waste steel slag red mud nickel slag copper slag and iron ore tailings is characterized by high yield low utilization and rich iron content ≥29% Their utilization as resources can be valuable in creating a circular economy
·Iron ore tailings IOTs are an important solid waste in the mining industry which can pollute the environment and endanger human health However the disposal and high value added utilization of iron tailings have always been a challenge Notably superconducting high gradient magnetic separation S HGMS technology is a promising technology in mineral
·Keeping in view the rising demand for iron and steel in India fresh exploration of iron ore resources and thereby generation of mining wastes is on the anvil Iron ore overburden which is generated during selective mining is one of such low grade iron resources which cannot be directly subjected to iron making because of the low iron content
·Zinc extraction residue a solid waste generated from the treatment of zinc containing dust in rotary kilns is commonly stockpiled in steel companies for extended periods It poses significant disposal challenges and environmental pollution risks So far research on the treatment of zinc extraction residues has been slow inadequate and sporadic For this gap a
·The cold rolling oily sludge CROS is a solid waste generated from the cold rolling process comprising a mixture of iron powder and rolling oil or grease with complex components and containing pollutants such as heavy metal Biswal et al 2009 Liu et al 2011 Based on the Chinese "National Hazardous Waste List" CROS are classified under the
·In order to comprehensive utilization of iron ore tailings this experimental research was to investigate the possibility of using the residues after iron recovery from iron ore tailings as raw materials for the preparation of cementitious material abbreviated as TSC including analyses of its mechanical properties physical properties and hydration products
·The zero waste technology is developed for recycle and utilization of iron and steel plant ore fines and coal fines are also generated during mining and transportation
