Airport; Weather
All Runways were wet; taxiway conditions were listed as poor to medium. After crossing Runway XX; I slowed to 5 knots to make the left turn onto Taxiway X. The aircraft began the turn; then 45 degrees into the turn began sliding forward. I applied the brakes; and came to a complete stop with all gear remaining on the runway. Ground was called; and they arranged for an escort for a [company] tug. The tug began to slide also; so a sand truck was called. The sand truck slid sideways initially; but began sanding the area and remaining taxiways. Following the application of sand; the tug was able to connect to the aircraft and put us back on centerline. We were then pulled forward out of the icy area. As the taxiways were now sanded; the taxi and departure were uneventful.Cause: Poor to medium taxiway conditionsSuggestions: Sand all taxiways when conditions are listed as poor to medium.
B767 Captain reported that ice on a taxiway resulted in a momentary loss of aircraft control.
