IRON AND STEEL

Briquetting. Briquetting, another form of agglomeration, involves heating the ore and pressing it into briquettes while the materials are still hot. Once the briquettes are c ooled, they are sent directly to the blast furnaces. Reduction of the Iron Ore There are two basic met hods for reducing iron ore: C direct reduction; and

Ultrafast Plug Flow Agglomeration—Exploiting Hydrophobic ...

The selective agglomeration of a fine coal tailings stream using a high internal phase emulsion binder was investigated using a continuous steady-state plug flow through a high shear constriction. The emulsion binder effectively switches off the viscous resistance to particle–binder collision and adhesion, revealing the remarkable underlying speed of hydrophobic interactions.
