       China's stricter environmental regulations and depleted mine supplies could lead to a shortage of tungsten if no new mining projects come online in the next few years, research firm rosekill has reported. Despite a 5 per cent year-on-year increase in demand, global mine production of key metals fell from 82,100 tonnes to 82,000 tonnes in 2018.
Government environmental regulations have forced some producers in jiangxi, hunan and fujian, China's largest tungsten mines, to suspend production. Moreover, as mines mature, their products and grades decline.

Russian production is expected to increase in the short term, but many of the country's established tungsten mines have the same problems as older Chinese mines, face grade depletion and may be shut down, meaning new mines will need to be developed in the next few years, said Jessica Roberts, manager of rosekill.
Vietnam, the second-largest producer outside China, also has mine supply problems. In 2017, the country produced 6,600 tons of tungsten, but that number fell to 6,000 tons in 2018 and may not grow. According to Roberts, Masan Resources, Vietnam's leading tungsten producer, is running at full capacity and is increasingly buying concentrate from third parties to boost its tungsten production at the chemical plant. All this points to the need to develop new tungsten deposits.
While the uncertainty may be bad for end-users, it is certainly good news for tungsten prices, which hit a four-year high of $350 a tonne in June 2018 as Chinese smelters were forced to shut down, according to the report. As domestic production resumed, prices fell back and hit $275 in January, where they are now. "So far, APT prices have been very stable in 2019," Roberts said. There are a number of factors that could drive prices higher for the rest of 2019.

In addition, Roberts pointed out that the tungsten demand base in the tool industry is large and stable, mainly for cemented carbide tools and other tool materials, such as high-speed steel, which is directly related to manufacturing activities. Among them, auto parts processing is a large market for tungsten - containing tools. Tungsten applications in automotive and aerospace have grown over the past few years and are expected to continue to increase, increasing the traditional use of metals.
Roberts said conditions for APT to meet a modest price increase in 2019 include: a planned launch of new mines in Spain; Positive results have been achieved between China and the United States. APT prices rose slightly from the end of the second quarter to the third quarter, and then continued to decline due to seasonal factors in the fourth quarter.
