Projects that will deliver more zinc concentrate to market include Vedanta's Gamsberg mine in South Africa and three Australian projects, namely Dugald River owned by MMG, another mine run by New Century Resources and Glencore's Lady Loretta mine.
Wood Mackenzie analyst Jonathan Leng expects supplies of zinc concentrate to rise by 300,000 tonnes in 2018, 900,000 tonnes in 2019 and 1.25 million tonnes in 2020.
Stocks of zinc in LME approved warehouses, which now stand at 239,625 tonnes, are down 60 percent since September 2015 when Glencore slashed 500,000 tonnes of annual zinc production.
China accounts for about half of global zinc consumption estimated at around 14 million tonnes this year.
Goldman sees a zinc deficit of 522,000 tonnes in 2018 and a shortfall of 120,000 tonnes in 2019, while Citi sees a 335,000 tonne deficit this year and 164,000 tonne surplus next year.
The construction industry accounts for about 50 percent of global demand, while the rest is mainly distributed between transport, infrastructure, consumer products and industrial machinery.
