is formed.Aluminum dross is a complex oxide material containing Al2O3 calcined aluminous ore is treated with a mineral acid such as H 2 SO 4. The treatment produces soluble aluminum salt (e.g. aluminum sulfate) and the silica appears in the residue with the bulk of the impurities. Iron andThe particles range in size from submicron to as much as 40 microns (equivalent spherical diameter). The kaolin is mined with diesel or electric shovels or draglines and loaded in trucks for transport to the processing plant or dropped directly from the dragline into a blunger. The blunger chews the kaolin into small lumps and mixes it with ...Kaolinite is a clay mineral
