摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

摘要： A process in which alumina is extracted from bauxite with an aqueous alkali solution, and a desilication product is precipitated such that the product is not contained in a bauxite residue and does not form a complex. The desilication product is mixed with a calcium compound, and the mixture is calcined, to thereby solubilize and recover an alkali component of the product. In addition, an alkali component is removed from a residue (a solid product), and the residue is effectively used as a resource.

摘要： The present invention provides a method of producing a highly pure aluminum primary base metal having a purity of at least 99.95 wt % (3N5), or a still higher purity close to the 4N that is a purity value of a secondary refined base metal. Alumina, the Si component of which is decreased by acid cleaning, is placed in a Hall-Heroult electrolysis cell as a main raw material. An aqueous solution of sulfuric acid, an aqueous solution of sulfuric acid plus hydrofluoric acid, or the like is used for acid cleaning. In order to remove Si, an acidic aqueous solution heated to at least 40° C. is preferred. Use of deashed coke and/or pitch as a carbon material for anode in addition to the use of acid-cleaned alumina produces a highly pure aluminum primary base metal in which the Si and Fe components are further decreased.
