London copper slipped on Friday and was heading for its largest weekly loss since the start of 2015, as steel and iron ore prices plunged, speeding a pull back in commodities on concerns over China’s economy and a stronger dollar, Reuters reported. Three-month copper on the London Metal Exchange edged down by 0.2% to 36,560 a ton, extending losses from the previous session when prices fell 1.7% and reached the weakest since April 18 at $4,764 a ton. Prices were tracking for a 5.4% weekly loss, the largest weekly decline since January 2015.
