No survivors have been found from Aseman Airlines flight EP3704, which disappeared from radar on Sunday morning, around 45 minutes after taking off from Tehran on a domestic flight.
Search helicopters finally located the crash site after a break in the weather on Tuesday at a height of around 4,000 metres in the Dena range.
But the altitude and weather conditions have meant that helicopters cannot land to recover the bodies of the dead and they are being brought down on the backs of emergency personnel to a road at the foot of the mountain.
"We decided that those bodies that can be carried down would be brought down by army commandos or by the emergency services," he said.

Mohsen Mehralizadeh, the governor of Isfahan province from where part of the recovery operation is being coordinated, said 32 bodies had been found so far.
The first seven were being brought down on Wednesday morning, state television reported.
Crevasses and the risk of avalanches made the operation hazardous and time-consuming, emergency officials said.
Aseman Airlines was blacklisted by the European Commission in December 2016.
It was one of only three airlines barred over safety concerns -- the other 190 being blacklisted due to broader concerns over oversight in their respective countries.
