What is Goldschmidt Aluminothermic process?

Hans Goldschmidt improved the aluminothermic process between 1893 and 1898, by igniting the mixture of fine metal oxide and aluminium powder by a starter reaction without heating the mixture externally. The process was patented in 1898 and used extensively in the later years for rail track welding.

Which is not Goldschmidt thermite process?

With the help of this process, metals like chromium and magnesium are extracted in a highly pure state on a commercial scale. Hence, aluminium metal is not extracted by Goldschmidt thermite process. Therefore, the given statement is incorrect.
