What does a alumina refining do?
Generally speaking, the chemical process is known as the Bayer process. It is used to turn mined Bauxite ore into alumina. The fist stage is known as Digestion. The Bauxite is ground in mills and then slurried up with hot, caustic soda solution. this dissolves the Alumina that is contained in the Bauxite ore. Other impurities found in the Bauxite such as silica, iron and titanium compounds are not dissolved. The next stage is known as Clarification. The Bauxite ore and Caustic soda slurry are passed into rows of Settler tanks (also known as thickeners or clarifiers). Usually with the help of a diesel based polymer known as flocculant and a defoamer, the mud and impurities will settle to the bottom of the Thickener, leaving a clear alumina charged 'pregnant liquor' overflow. This is further filtered and passed on to the next stage in the process known as Precipitation. During Precipitation, the liquor is cooled, concentrated and stirred in open top tanks until it forms crystals. Pure alumina is added to the mixture to encourage alumina trihydrate crystals to form. It is then moved along to the next stage of the process. In Calcination, the alumina trihydrate crystals are washed, filtered and heated in gas fired kilns (usually at temperatures exceeding 1 100 degress celcius). This removes the 3 molecules of water from the alumina trihydrate. The remaining fine white powder is known as alumina. It is then typically cooled and stored until it is ready to be sent to a Smelting facility to be made into Aluminium. Typically, you will use 2 tonnes of Bauxite to produce 1 tonne of Alumina. There are a number of side streams of the process but this is just a very brief overview..
What is blood a compound mixture or element?
mixture
Is syrup a compound?
Syrup is a mixture.
Is the water with which you just watered the lawn a mixture or a pure compound?
It is almost a pure compound but it will have had things in it so in effect it is a mixture.
Is a distilled water a mixture?
No . It's just heated to kill germs . Nothing is added .
How do you break aluminum alumina bond?
I'm not quite sure what you mean because alumina is a compound (aluminum oxide or Al2O3) and aluminum is an element. Therefore, there isn't a bond per se from aluminum to alumina... just aluminum-aluminum bonds and aluminum-oxygen bonds. I do know that alumina will dissolve in a strong base solution, such as KOH or NaOH, and so if you have a layer of alumina on an aluminum sheet, a strong base solution will remove it. Also, a strong acid will dissolve the aluminum. (I do have to admit I'm not entirely sure what the effect of a strong base on aluminum and a strong acid on alumina is, though... and that might be a problem... hmm...)

Is soda just opened a compound element or mixture?
This is a mixture of carbon dioxide and water.
Is it always possible to identify something as an element compound. Substance or mixture just by looking at it?
Very rarely is possible; generally to identify an element or compound it is absolutely necessary to realize a deep chemical/physical analysis.
Is it possible to identify something as an element compound pure substance or mixture just by looking at it?
Very rarely is possible; generally to identify an element or compound it is absolutely necessary to realize a deep chemical/physical analysis.
Can you use silica in place of Alumina?
assuming your talking about column chromatography. Yes, they are just two different absorbents that are polar to slow the polar eluate as it runs down the column.
Is soda just opened an element a compound a solution homogenous mixture or a heterogeneous mixture?
Unless the soda contains suspended solids, it is a homogeneous mixture.
Is syrup a compound?
Syrup is a mixture.
Is a solution a mixture or just a solution?
a solution is a mixture as a solution is made only when two substances are mixed together so a solution is definitely a mixture!
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
What is the sugar from a watery sweet mixture?
Sugare from a watery sweet mixture is just sugar (dissolved in water).
