and larger and greater specifications are desired. The initial step of metallurgy should be to create aluminium oxide. In alumina oxide production with sintering process‚ we need to first create the raw materials compounded by bauxite‚ limestone and alkali into clinker. The sintering process is completed within the vertical roller mill whose inner temperature is 1300℃. The final phase of aluminium oxide manufacturing is to roast aluminum hydroxide into alumina oxide. The inner temperature is about

The graduations are oversized by a proportionate amount‚ for example‚ when constructing a pattern for aluminium alloys‚ the pattern maker uses a contraction

known as an ore. The method used to extract metals from ores depends on the reactivity of that metal. Some unreactive metals can even be found in the native state‚ like gold. On the other hand‚ most metals are too reactive to exist on their own like aluminium‚ which has to be extracted using a method called electrolysis. And some moderately reactive metals that are in the middle of the reactivity series can be extracted using reduction of oxides like iron. Gold is not found in a mixture or
