Salt slag is a waste material generated by secondary aluminium processing (the recycling and smelting of new aluminium from scrap, aluminium dross and other wastes). Due to the nature of the contaminants it contains, salt slag (or salt cake as it sometimes known) is classed as a hazardous waste in most countries and banned from landfill ...
Slag is a typical byproduct generated during high-temperature metallurgical processes. It must be treated appropriately to meet the increasingly strict environmental requirements and to realize the economic benefits. 1, 2 The present topic, “Slag Metallurgy and Metallurgical Waste Recycling,” collects eight articles, which demonstrate the ...
Having continued to develop slag and dust recycling technologies and explore new uses for recycled materials at our Kobe, Kakogawa and Takasago works, we managed to reduce the volume of waste sent to landfill in fiscal 2011 by approximately 30,000 tons compared to the previous year.
Recycling of materials avoids processing costs for waste treatment. In addition, some spent batteries are classified as hazardous wastes, increasing transportation, treatment, and disposal costs, as well as the effort needed to achieve regulatory compliance. Lithium-ion batteries are classified as Class 9 miscellaneous hazardous materials,
Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to
