Benefits of Agglomeration in an SX-EW Process for Copper …
Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered. For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator.
Mechanism and Prevention of Agglomeration/Defluidization during

Moreover, a mathematical model was developed to predict the high-temperature defluidization …
Review of Organic Binders for Iron Ore Agglomeration
Iron ore agglomeration is a wet agglomeration process, and moist "green-balls" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from green-ball formation to pellet hardening.
Review of organic binders for iron ore concentrate agglomeration …
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make …
