At the Multi Commodity Exchange, zinc for delivery in current month traded lower by 15 paise, or 0.11 per cent, to Rs 140.20 per kg, with a business turnover of 126 lots.
The metal for delivery in October fell by a similar margin to trade at Rs 140.85 per kg in a turnover of 16 lots.
Marketmen said the fall in zinc prices at futures trade was mostly in line with a weak trend in select base metals at the London Metal Exchange.
