What are the Fairly reactive metals found as ores compounds often oxides and carbonates and can be extracted using carbon to reduce the metal compound to the pure metal?

Why oxides of high reactive metals cannot be reduced by carbon?
Except through electrolysis a metal in an oxide can only be replaced by a more reactive metal. If fact that is one of the measure of reactivity. Highly reactive metals such as magnesium are actually stronger reducing agents than carbon, so rather than carbon reducing their oxide, they will reduce oxides of carbon.
What metals can be extracted from their oxides using carbon?
The first few in the reactivity series... copper, lead, platinum and silver.. Gold occurs native.
Is carbon dioxide an acidic gas?
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
Can you burn metals to make metal oxides?
Yes, many of the more reactive metals can be burnt to produce their oxides. Magnesium is a good example of this which burns with a white light to produce MgO. Not all metals need to be burnt. Iron is oxidised by oxygenated water to form Iron oxide (rust) and aluminum is oxidised in air. Less reactive metals however, will need different conditions to be oxidised. The least reactive metals such as platinum and rhodium are very difficult to oxidise.
Which metal oxides will not react with carbon?
Metals which are above Carbon in the reactivity series, eg. Magnesium. These metals need to be extracted by electrolysis.

Fairly reactive metals found as ores?
no because if the metals were reactive then they would react with elements in the air non reactive metals are found in there native state like gold and silver.

Why is carbon reduction process not applicable for reduction of oxides of metals like Mn and Cr?
carbon can not reduce more electropositive metallic oxides like of Mn and Cr. Thus carbon reduction process not applicable for reduction of oxides of metals like Mn and Cr .

What metal oxides can be converted to the metal by carbon reduction but not by hydrogen reduction?
any metals below carbon in the reactivity series. :)
What type of chemical reaction is used to extract metals from their naturallly occurring compounds like oxides or chlorides?
For example reduction with hydrogen and carbon from oxides, reduction with other metals from chlorides, etc.
Is aluminium extracted by heating their oxides with carbon?
No, it cannot be extracted this way as aluminium is a much stronger reducing agent than carbon and has greater affinity to oxygen. It is rather extracted by the process of electrolysis by passing electricity through molten aluminum ore which is bauxite mixed with cryolite.
Which oxide can be reduced to the metal using carbon?
Anything below carbon on the reactivity series.
