Zinc prices fell marginally by Rs 0.10, or 0.11 per cent, to Rs 90.10 per kg in futures trade today, as speculators reduced their positions at prevailing levels in view of approaching monthly expiry.
Sluggish demand at spot markets also put pressure on the zinc prices in futures trade.
At the Multi Commodity Exchange platform, zinc for delivery in July fell by Rs 0.10, or 0.22 per cent, to Rs 90.10 per kg, with a turnover of 627 lots.
The metal for delivery in August contract also moved down by Rs 0.05, or 0.05 per cent, to Rs 91.35 per kg, with a business volume of 387 lots.
Market analysts attributed the weakness in zinc at futures market to sluggish spot demand and slight weakness in base metals overseas on weak US data and the Federal Reserve's downbeat view on the economy.
