Pyrometallurgical processingProcessing requires the handlingHandling of metallics and slagsSlag within integrated smelterSmelter flowsheets. Such handlingHandling is typically done through slow cooling methodsCooling methods, such as casting, or through rapid methods such as water granulationWater granulation. Examples for metallics handlingHandling include casting into pits or into casting machinery. Such methods bring about risks related to moltenMolten materials handlingHandling, dilution via excavation of pits, or machinery down-time and consequently curtailed production time. Examples of water granulationWater granulation for metallics and slagsSlag include disintegration technologyTechnology with impinging water jets or pond-type coolingCooling baths. For metallics as well as slagsSlag, such granulationGranulation methods present an inherent risk of explosions, which are managed through engineered safeguards. As is noted, although these methods have been practiced for centuries, they are not ideal tools for the metallurgist as they continue to present risks. The advent, development, and commercialization of large-scale atomizationAtomization technologyTechnology by Ecomaister Korea, now known as UNECO, have, however, created a new tool for metallurgists that permits the granulationGranulation of moltenMolten materials such as metalsMetal, mattesMatte and slagsSlag without the use of water. The absence of water and the rapid processingProcessing of these moltenMolten streams, in turn, creates the potential for energy recoveryEnergy recovery and reintegration from moltenMolten streams into metallurgical flowsheets. Thus, atomizationAtomization technologyTechnology creates new possibilities for the processingProcessing of metalsMetal, mattesMatte, and slagsSlag and the recoveryRecovery and reuse of their energy in nickelNickel and copper smelterCopper smelter designsDesign. We elaborate on practiced examples of atomizationAtomization technologyTechnology and its advancing use in metallurgyMetallurgy.
