Review of Agglomeration Practice and Fundamentals in Heap Leaching

Scrutton in 1905 is one of the earliest references to agglomeration. Scrut-ton agglomerated ore by rolling it down a chute inclined at 60 and stacked the agglomerates in a vat leach (very large vessel filled with ore and completely saturated with leaching solution). The initial work on iron ore pelletization began a few years later, in 1911 ...

Mechanism and Prevention of Agglomeration/Defluidization during ...

In the case of fluidized-bed reduction of iron ore, earlier works [8, 9, 10] indicated that sticking occurred mostly during metallization of ore. The defluidization tended to be preferred at a high fractional reduction and metallization degree. Some ore particles were precipitated by the metal iron with the fibrous shape on the particle surface.

Heap leaching a stack of gold - MiningFeeds

Agglomeration drums are also called ore drums, agglomerators, and heap leaching drums. Agglomeration is based on a rotary drum design that tumbles ore fines, in the presence of the leachate, through its interior to promote uniformity and to mix the leachate and fines. The agglomeration step happens after the ore is crushed, but before it is heaped.
