Of agglomeration of ores

Agglomeration and column leaching behaviour of nickel .

Agglomeration and column leaching behaviour of 3 different Ni laterite ores with varying sizes are reported in this paper. The results suggest that: • Agglomeration is shown to be a crucial pretreatment step for successful heap leaching of run-of-mine and/or comminuted Ni laterite ores.

Mechanism and Prevention of Agglomeration/Defluidization .

The mechanisms of agglomeration and defluidization and fluidization characteristic of iron oxide particles were investigated based on the theory of surface diffusion, interface reaction, surface nano/microeffect, and phase transformation. Moreover, a mathematical model was developed to predict the high-temperature defluidization behavior by the force-balance and plastic-viscous flow mechanism .

Agglomeration technique improves heap leaching process .

In the case of heap leaching, agglomeration relies on a binder (typically cement) and tumbling motion to cause coalescence, or the building of fines into larger particles. Agglomeration drums (sometimes referred to as ore drums or agglomerators) are the equipment of choice for agglomerating ore fines in preparation of heap leaching.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the .
