Micro-pelletizing is the process of agglomerating material fines into small pellets, ranging in size from 20-60 mesh. Like all agglomeration techniques, micro-pelletizing provides a host of benefits including: Significant dust reduction/elimination: micro-pelletizing prevents material from becoming windblown, and thus less product is lost due to …
Smelting is one of the primary routes to producing copper, and as such, plays an important role in meeting the ever-surging demand for the red metal in the transition to a low-carbon economy. While various smelting technologies exist, they all depend on a dry feedstock …
Fly ash is a fine, powder-like material generated from coal-burning power plants. And despite an increase toward more sustainable energy production, coal-burning power plants are still prevalent, producing fly ash that could serve as a valuable commodity. Thus now is an important time as any …
As one of the most recyclable materials around, aluminum recycling is a profitable business, both for industry and for the environment. According to the Aluminum Association, almost 75% of all aluminum ever produced is still in use today. The Aluminum Association also states that the …
Phosphate rock is mined all over the world to produce a number of phosphorus products that are essential to plants and animals- namely, fertilizers and animal feeds. Many predict that demand for phosphate, particularly for use as a fertilizer, will only rise, as the world …
Rotary kilns are used throughout various industries from mining to chemical production and even waste management. And while they are capable of processing a broad range of materials, one essential aspect of any rotary kiln operation is preparing the material – whatever it may be …
Catalysts have become a cornerstone of modern industrial processing, bringing otherwise-out-of-reach processes into the realm of practicality, maximizing the efficiency of reactions, and promoting more sustainable industrial processes; the extent to which catalysts impact modern industry are nearly immeasurable. The effectiveness of any catalyst rests …
Rotary kilns have become an essential bulk solids processing tool throughout a number of industries; their ability to facilitate physical and chemical changes through carefully controlled thermal treatment is nearly limitless in application. Because rotary kilns utilize high temperatures to initiate and carry out reactions, …
Catalyst regeneration via thermal desorption has emerged as a solution for industries grappling with spent catalysts, which pose liability risks and waste management challenges. As processors seek to lower operating costs and minimize their environmental footprint, many are turning to catalyst regeneration through this thermal …
Red mud, also commonly called bauxite residue, is a waste product left over from the Bayer process, in which alumina is extracted from bauxite ore. Produced in mass quantities (estimates hover around 1-2 tons of red mud per ton of alumina produced), red mud has …
