Aluminium sulfate - Wikipedia

Aluminium sulfate is used in water purification and as a mordant in dyeing and printing textiles In water purification, it causes suspended impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily This process is called coagulation or flocculationInnovative Process Solutions towards recycling of Salt ,“Leaching process investigation of secondary aluminium dross: The effect of CO 2 on leaching process of salt cake from aluminum remelting process” Peng Li, Min Guo, Mei Zhang, Lidong Teng, Seshadri Seetharaman Metallurgical and Materials Transactions B, DoI: 101007/s11663-012-9678-7 4Management of the Salt Cake from Secondary Aluminum Fusion ,The process carried out at the Iberian business of light alloys (Iberica de Aleaciones Ligeras, S L, IDALSA), a Spanish refinery, is presented This company has implemented several new technologies in order to minimize the salt cake generation from secondary aluminum fusion processes

Secondary Aluminum Processing Waste: Salt Cake

RUSAL Challenge: Cost-effective Processes to Recover and

Salt cake (‘slag’) is a toxic and hazardous by-product generated during aluminum processing It is mainly composed by salts (KCl and NaCl) that, instead of being wasted in landfills, can be recovered and re-used in the processEco-friendly aluminium salt cake recycling | Result In ,These are then used to evaporate the water by using a single-stage forced-circulation evaporator In this process, all available energy that is lost during the aluminium recycling process is reused, eliminating the need for additional energy for salt cake recyclingEfficient Aluminium Salt cake Recycling Technology ,This is a threat to the aluminium production industry as costs to process salt slag are becoming extremely high Due to the monopolisation of re-processing options, it is a financial security issue for the aluminium recyclers as they are in the hands of the nine salt slag recyclers in operation
