Three of the rescued Chilean miners left hospital and returned home on Friday.
Doctors in Copiapo declined to identify which of the miners had been discharged for privacy reasons.
Medics say most of the men are in surprisingly good shape and should be able to leave within the next 48 hours.
Three miners have had minor dental surgery, while the oldest of the group 63-year-old Mario Gomez is receiving treatment for pneumonia.
Gomez and his colleague, Mario Sepulveda, also have the lung disease silicosis.
The world’s media has now surrounded the hospital where they are being treated.
The Chilean government says it will care for the miners for at least the next six months.
The group spent 69 days buried 700 metres underground after the mine they were working collapsed on August 5.
