EQUIPMENT SPOTLIGHT: THE PUG MILL (PADDLE MIXER)Pug mills serve to mix and condition feed components for the smelter. Mixing not only conditions the agglomerates and de-duststhe material, but it also ensures a uniform product.
Pug mills increase efficiency in the smelting process so much so, that companies often will purchase two mixers (one as a spare). Learn more at: FEECO.com/copper-pug-mills/
EQUIPMENT SPOTLIGHT: THE AGGLOMERATION DRUMAgglomeration drums help to maximize recovery rates by makingore fines more uniform in shape and size, which allows the leachate to more effectively percolate through the heap (as seen in theillustration above). The agglomeration step also serves to begin the leaching process prior to the heap. This increases overall efficiency and ultimately, recovery rates.

METAL PROCESSINGTransforming Ores into a Refined Product
METAL PROCESSING SOLUTIONSFEECO is a leader in metal and mineral processing. We provide custom pug mills for concentrates, and agglomeration drums for the heap leaching/SX-EW process. Our agglomeration drums are utilized in some of the world’s largest and most environmentally advanced mines.
We can also provide all of the handling equipment to support the process. For more information, contact us today at FEECO.com/contact
Metals make up the world around us. From structures to electronics, much of the world around us wouldnot be possible without metals. Various processing techniques are used to transform metal-bearing oresinto a refined metal product, ready to be transformed into various components for application.

PYROMETALLURGY HYDROMETALLURGY
AKA: SMELTING AKA: SOLVENT EXTRACTION ELECTRO-WINNING
PRODUCTION METHODS
USED FOR:
WORKS BY: Concentrating metal-bearing oresand then smelting them
WORKS BY: Leaching metals from ore and thenextracting metal from the impregnated solution
Sulphide ores USED FOR: Oxide ores and low-gradesulphide ores
PYROMETALLURGY
The pyrometallurgical approach for processing copper is illustrated below. Please note that the processmay vary depending on the type of metal being processed.
HYDROMETALLURGY
The hydrometallurgical approach for processing copper is illustrated below. Please note that the processmay vary depending on the type of metal being processed.
