Narrative:

On a recurrent instrument training flight under IFR conditions we descended from 7;000 ft with vectors to the localizer back course at ZZZ. We picked up unexpected mixed ice from 5;000 to 4;000 ft; totaling approximately 1/4 inch on leading edges and windshield; limiting forward visibility. Descent continued uneventfully to 3;000 ft; with no additional ice accumulation. We made an uneventful approach.for landing; we avoided flap use and kept speed higher than usual to compensate for ice accumulation. Despite this precaution; the aircraft stalled without a pre-stall buffet at 10 ft above the runway; 10 KTS above vmc. The left wing dropped with the stall; the landing gear impacted the runway and the aircraft bounced into the air. Pilot applied full power for an uneventful go-around.after landing; the left propeller tips were noted to be bent; consistent with a prop ground-strike. There was no other damage to the aircraft; no ground contact marks on the wing or fuselage; no landing gear damage; and no injuries to the pilot or instructor. The discovery of the bent prop tips came as a surprise to both the pilot and the instructor.the cause of this incident was inadequate airspeed into the landing; resulting in a stall at very low altitude. Contributing factors were the airframe icing; resulting in higher than normal stall speed and windshield icing limiting forward visibility and making height above the runway more difficult to judge.

Title: A PA30 pilot on a recurrent instrument training flight lost control of the aircraft when it stalled in the landing flare after accumulating ice on the wings and windshields during the approach. After striking the ground with the left prop a go around was initiated and a subsequent landing was without incident.
