agglomeration high clay copper ores

    Agglomeration technique improves heap leaching process

    Agglomeration technique improves heap leaching process. The impregnated solution can then be collected at the bottom of the heap so that the copper can be recovered. Ores with a high presence of fines and/or clayey particles result in poor heap permeability as the fines clog spaces The agglomeration of ore fines and clay,

Crushed ore agglomeration and its control for heap leach

Generally, drum agglomeration is practiced for ores containing high clay contents such as nickel laterite/saprolite ores (Kappes, 2005). Crushed ore is agglomerated much like fine tailings, but preferred operating conditions and equipment are different such as more binder (5–7.5 kg/t), considerably more water (16–22%), and longer curing times (typically 72 h).

2020-05-15· ABSTRACT This article reviews agglomeration practices for precious metal and copper heap leaching. Both industries prefer drum to conveyor agglomeration, particularly for clayey ore or ore having a high fines content. Precious metal heap leaching operations opt for cement in a dosage from 2.5 to 10 kg cement/t of ore (5–20 lb/ton) added to a cyanide solution. Copper ores are agglomerated

Evaluation of stucco binder for agglomeration in the heap

Agglomeration pretreatment is required for ores which either contain excessive amounts of clay or an excessive quantity of fines generated during mining and crushing. A feed requiring crushing to a nominal size i.e. ¾ inches (19 mm) or finer will need agglomeration, especially if clay constituents are present (McClelland, 1988).

Benefits of Agglomeration in an SX-EW Process for

Copper is a versatile metal used in many of the products that modern civilization relies on, from electronics to infrastructure. For decades, smelting has been the primary approach to copper extraction. Although this method has proven to be effective for high grade sulfide ores, it has not been an option for other ore types, namely oxide ores and low grade sulfide ores.
