Experimental processing of salt slags from an aluminum ...The conventional recycling process using salt rotary furnaces is thermally inefficient and environmentally unacceptable because of the salt slags produced. HydroQuebec has developed and patented a new saltfree more » technology using a rotary furnace heated by an electric arc between two graphite electrodes, called DROSCAR{reg_sign}.
ArcelorMittal honored for slag recycling effort ... · Using slag in this way increases the sustainability of the mill's operations and saves money compared to extracting and using primary natural resources, says the firm. In 2016 ArcelorMittal Ostrava recycled on average 1,900 metric tons of enriched slag per month and in the process saved a more than 865,000 (€735,000).
RECYCLING OF PLATINUM GROUP METALS FROM AUTOMOTIVE ...hydrometallurgical or pyrometallurgical processes. Pyrometallurgical methods Today the recycling of spent alysts is carried out mainly by pyrometallurgical processes. The principle of these methods is to generate a liquid slag that is formed by the ceramic part of the alyst and to collect the precious metal fraction in a metal bath.
Slag: From Byproduct to Valuable Construction MaterialJul 29, 2014 · Slag is a byproduct 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 stay in the melt while the others are removed.
