SCALE-UP OF MAGNESIUM NEW RHEOCASTING FROM A LABORATORY LEVEL TO AN INDUSTRIAL PROCESS

摘要

Sludge, dross and black dross are among the most demanding byproducts of Magnesium handling and recycling. They are reactive when coming into contact with water including hydrogen and ammonia formation. Especially black dross is a recycling problem being very reactive with its fine magnesium particles and high salt and magnesium oxide content. Together with LKR Non-Ferrum developed a way of treating these by-products either in a dry or a wet way, depending on the incoming material and recovering its components that are magnesium, magnesium oxide and salt. The products from both processes can be reused and are not reactive. With the recovery of metallic Mg the treatment is an economical and ecological feasible way to process sludge, dross and black dross.
