Nov 23 (Reuters) - Shanghai zinc prices jumped 4.6% on Tuesday to their highest in nearly three weeks amid global supply concerns after miner and commodity trader Glencore floated plans to put its zinc sulphide operations in Italy on hold for maintenance.

The most-traded January zinc contract on the Shanghai Futures Exchange was up 3.9% at 23,805 yuan a tonne, as of 0324 GMT, having hit its highest since Nov. 4 of 23,980 yuan a tonne.

Three-month zinc on the London Metal Exchange eased 0.1% to $3,345 a tonne, having scaled on Monday to its highest level in more than two weeks.

Glencore said the zinc plant in Portovesme, with a capacity of 100,000 tonnes a year, will be put on care and maintenance until there is "a meaningful change in power market prices".

The premium of LME cash zinc over the three-month contract rose to $52.80 a tonne, its highest since Oct. 29, indicating tightening nearby supplies as LME inventories of the metal fell to the lowest since July 2020 to 175,025 tonnes.
