* Iron ore futures gain as much as 2.4%

* Steel mills’ improving margins fuel demand for high-grade ore - analyst (Adds details, chart; updates with closing prices)
BEIJING, May 13 (Reuters) - Benchmark iron ore futures in China jumped to their highest level in over nine and a half months on Wednesday, driven by higher demand for the steelmaking ingredient as steel mills ramped up output amid improving profit margins.
The most active iron ore futures on the Dalian Commodity Exchange, for September delivery, climbed as much as 2.4% to 647 yuan ($91.22) per tonne. The contract closed up 2.1%, its highest level since Aug. 1.
“The margins are improving over the last 15 days in China’s ferrous industry, this motivates the mills to ramp up their production and also use high-grade iron ore,” Singapore-based steel and iron ore data analytics company Tivlon Technologies wrote in a note.
Spot prices of iron ore with 62% and 65% iron content for delivery to China have both jumped 5% so far in May, and stood at $88.8 and $105.5 per tonne, respectively, on Tuesday.
Tivlon Technologies however warned that with rising utilisation rates at blast furnaces and electric arc furnaces, profit margins might narrow, leading to lower interest in high-grade iron ore.
