Aluminum Salt Cake, what is salt cake? salt cake definition


Rotary furnace operations processing scraps and drosses use salt flux for the same reasons mentioned earlier, but the ratio of the salt flux to the contained oxide in the resulting by-product is different.


Two modes of operation are common: “wet” and “dry” with the difference being the amount of salt flux added and the rheological consistency of the molten black dross.


In the wet mode, enough salt flux is added to make a liquid pool of molten salt with the approximate consistency of water.


In the dry process, less flux is added and the salt cake has a much drier consistency. The metal content of salt cake is generally lower than that of black dross.
