This week’s highlighted resource is a project profile on copper ore drums. Agglomeration drums (aka copper ore drums) are used in the heap leaching process to agglomerate ore fines so that the leaching agent can more effectively percolate through the heap, maximizing metal recovery. FEECO …
There are many choices on the market when it comes to agglomeration equipment. Additionally, new uses are being developed all the time, making current equipment options increasingly flexible. Below, we’ve provided a quick overview of some of the most common types of agglomeration equipment. Click …
Granulation can be considered the same as pelletization, the method of agglomeration or particle size enlargement, but it often refers specifically to applications within the fertilizer industry. Granulation is generally carried out in a granulation/agglomeration drum if a chemical reaction is involved. The process works …
This week’s photo highlights a rotary drum temperature inspection. An IR gun, pictured, is directed at the rotary drum, to record the surface temperature of the object in sight. Items such as the drum shell, drive components, bearings, and even the material as it discharges …
This week’s photo shows an agglomerator used for processing gold ore. The agglomerator, or agglomeration drum, agglomerates ore fines after they are crushed. This process creates a more proficient leach because the leaching solution is better able to permeate through the heap when the particles …
This week’s photo highlights several rotary dryers under production at FEECO. The photo was taken in FEECO’s fabrication facility, just shortly after our founding in 1951. For decades, many industries have been faced with the same problem: product moisture. Depending on material composition, moisture can …
Tailings, or the material remaining after a valuable component has been separated from the gangue, have long plagued the mining industry with management costs, liability risks, and disposal challenges. Due to their toxicity, tailings pose a number of risks if not properly managed. Furthermore, the …
While nickel is perhaps most commonly known for its use in coins, it is also an important material in many industrial processes. Nickel’s high melting point, ductility, and resistance to corrosion when alloyed lends itself to a wide range of industrial applications and materials, making …
The solvent extraction electro-winning process (SX-EW) is a hydrometallurgical means of extracting, purifying, and concentrating metals. SX-EW has continued to demonstrate successful use in effectively extracting and recovering copper from low grade and oxide ores. As a result, SX-EW has quickly become a staple in …
This week’s post highlights a series of images: rotary tire wear patterns. A rotary drum tire is a support structure for the drum, and provides a place for pressure to be absorbed. As with any piece of equipment, they must be inspected and serviced, if …
