Iron-Ore Depletion Including Recycling roperld. Jul 03, 2001 Before the leap to prominence of the electric arc furnace (EAF), the food chain in steelmaking went something like this: at the top of the chain was iron ore, next was scrap and at the bottom was a variety of feedstock going by the names of direct reduced iron (DRI), hot briquetted iron (HBI—a form of direct reduced iron), pig

Treatment and Recycling of the Process Water in Iron

In order to ensure iron concentrate grade and iron recovery, a large number of processing reagents are selected and applied in the iron ore beneficiation. The process water carried plenty of residual processing reagents, and such wastewater with color depth and strong smell could seriously affect the environment and the local people.

Study of the recovery and recycling of tailings from

2014-12-1  The iron ore tailings in this study have particle sizes and particle shapes, which become easy to substitute other materials in the ceramic mass, as the clay used traditionally as a prime material is constituted of hydrated alumino-silicates with high contents of SiO 2 and Al 2 O 3, and commonly with some contamination of Fe 2 O 3, all of these

Soil Quality and Heavy Metal Pollution Assessment of

Mining activities have resulted in the existence of dumps, which generally present a perpetual danger of moving and transforming toxic elements. The experimental study was carried out in Nizna Slana (Slovakia) where the main source of emission was the iron-ore mining–processing factory focused on siderite mining. Siderit from Nizna Slana is highly ferrous with an increased level of the Mn
