Solution- Distillation method is based on the difference in between the boiling points of components of mixture Thus distillation is very good method for low boiling metals like zinc and Mercury As they will seperate by boiling fastly Liquation Process is used for refining the metals having low melting point compared to high melting impurities For eg: lead, tin Zone refining is a process which is based on the principle that the impurities in an ore of metal are more soluble in the melt state when compared to the corresponding solid-state of the impurities This method is used for semiconductors like Silicon, germanium Answer- From the above statements we can say that correct statement are A, B and D

Solution-

Distillation method is based on the difference in between the boiling points of components of mixture. Thus distillation is very good method for low boiling metals like zinc and Mercury. As they will seperate by boiling fastly.
Liquation Process is used for refining the metals having low melting point compared to high melting impurities. For eg: lead, tin
Zone refining is a process which is based on the principle that the impurities in an ore of metal are more soluble in the melt state when compared to the corresponding solid-state of the impurities. This method is used for semiconductors like Silicon, germanium

Answer- From the above statements we can say that correct statement are A, B and D.
