Most of the new tungsten mining projects coming up are yet to secure funding, but some are fully financed — two in Spain, and two in Russia, which hosts the largest tungsten mineral resources outside China. The first two are producer W Resources' 1,400 t/yr La Parilla mine, which started operating in late 2019 and shipped its first concentrate in early 2020, and the 2,060 t/yr Barrecuopardo mine, which also started running and shipping concentrate in late 2019, and is majority owned by investor Oaktree, to whom Ormonde Mining recently agreed to sell its 30pc stake.
In Russia, Wolfram is developing the 560 t/yr tungsten-tin Zabytoe deposit in the far east, also with mining having started in 2019 with first shipments in early 2020. Russian state strategic resources corporation Rostec is developing the other tungsten deposit, Tyrnyauz, in North Caucasus, as a 3,570 t/yr mine with a view to a 2023 start, and with an offtake agreement already signed with Wolfram for its tungsten and molybdenum ore.
Elsewhere, the 600 t/yr RHA mine in Zimbabwe has been expected to restart in mid 2020, Mironenko said. China's decision last year to ban imports of 32 kinds of scrap has released more tungsten scrap and residues for recycling outside China, which has eased the pressure on some of the primary raw material supply, he added. Chinese tungsten processors have also since invested in recycling projects outside the country, including in Malaysia.
While industrial scale mechanised mining dominates primary tungsten raw material supply, a minor portion of it comes from artisanal mines including in Bolivia in South America, Myanmar in southeast Asia and the Democratic Republic of Congo, Rwanda and Burundi in central Africa.
But the quality of artisanal concentrate varies and comes with impurities. Concentrate from the new industrial mines in developed countries also comes with higher impurities than competing Chinese raw materials, Gorbachev told delegates.
"As a consumer you can choose concentrate on price, quality or availability — and very rarely all three go together, usually you only get two. So if sourcing outside China, you have to compromise," Gorbachev said.
In terms of demand, the tungsten market is evolving but at a slower rate than predicted, he said. Transport accounts for 31pc of tungsten consumption, with other major uses including mining and construction (23pc), industrial applications (13pc) and defence (6pc).
The use is set to change within the transport segment as the move from internal combustion engine vehicles to electric vehicles (EVs) is set to lead to loss of market in transmission and engines and lower share of metalwork in body parts and therefore less tungsten use in tooling. Tungsten is set to find a new market in copper-tungsten connectors and potentially in niobium-tungsten oxide for lithium-ion batteries, an area currently in research.
