Is there a way to extract magnesium from talc(Mg₃Si₄O₁₀(OH)₂). If so how?

Magnesium is usually obtained by an electrolysis of molten MgCl2. Of course, you can decompose talc, but there are many cheaper sources of Mg for producing MgCl2 (eg mineral MgCO3)

I think that it is cheaper to produce elementar magnesium from magnesium oxide with elementar carbon (MgO + C ? Mg + CO)...but check me on this

i was thinking, wouldnt magnesium bond more strongly to the oxygen than the carbon?

i think I'll react it with an acid to get a magnesium salt then melt that over high flame... I'm doing this because  i need Mg on short notice

Buying will be probably faster.
