Because this material has a precise structure, uniform quality, and Large surface area, so excellent filtering effect.<\/p>\n<p><strong>The production of aluminum ingots consists of bauxite mining, alumina production, and aluminum electrolysis.<\/strong><br \/>\nThe bauxite ore is first mined, and aluminum ore powder is produced through water washing and grinding processes, and then four complex processes such as roasting are used to obtain alumina. There are three main types of bauxite for the production of alumina: gibbsite and monohydrate. Water diaspore, boehmite.<br \/>\nOf the proven global reserves of bauxite, 92% are weathered laterite-type bauxite, which belongs to the gibbsite type. These bauxites are characterized by low silicon, high iron, and high aluminum-silicon ratio, and are concentrated in Africa. West, Oceania and Central and South America. The remaining 8% is sedimentary bauxite, belonging to boehmite and diaspore type, of medium and low grade, mainly distributed in Greece, the former Yugoslavia and Hungary.<br \/>\nDue to the different characteristics of the three types of bauxite, each alumina production enterprise adopts different production processes, mainly including Bayer method, soda lime sintering method and Bayer-sintering combined method. Generally, high-grade bauxite is produced by the Bayer method, and medium and low-grade bauxite is produced by the combined method or the sintering method. Due to its simple process and low energy consumption, the Bayer process has become the most important method used in alumina production at present, and its output accounts for about 95% of the total global alumina production.<br \/>\nAlumina is electrolyzed to produce aluminum metal under the action of a strong current. This process is called electrolytic aluminum.<\/p>\n<p><img class=\"alignnone size-full wp-image-8310\" src=\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/02\/Alumina-Ceramic-Foam-Filter-Casting-Filtration.jpg\" alt=\"Filtraci\u00f3n por colada con filtro de espuma cer\u00e1mica de al\u00famina\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/02\/Alumina-Ceramic-Foam-Filter-Casting-Filtration.jpg 1024w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/02\/Alumina-Ceramic-Foam-Filter-Casting-Filtration-300x200.jpg 300w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/02\/Alumina-Ceramic-Foam-Filter-Casting-Filtration-768x512.jpg 768w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/02\/Alumina-Ceramic-Foam-Filter-Casting-Filtration-700x467.jpg 700w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Alumina Ceramic Foam Filter Casting Filtration can filter out the source of pollution generated in the aluminum casting process.
