The mainstream scrap tungsten price maintains steady. The transaction price excluding tax of domestic blade is ￥171.00-￥174.00/kg; imported blade is ￥181-183/kg; scrap tungsten bit still concentrates on ￥187.00-￥190.00/kg scrap pure tungsten block is ￥208.00-￥213.00/kg.

The price of the content of scrap tungsten grinding material which is more than 70W is ￥1.70 per kilogram tungsten, 50W-70W is ￥1.60 per kilogram tungsten, 30W-40W is ￥1.40 per kilogram tungsten, 10-20W is ￥0.80 per kilogram tungsten while 8W-10W is ￥0.70 per kilogram tungsten, which keep steady constantly.

Tungsten concentrate spot prices stay weak. Other kinds of tungsten products cannot avoid dropping destiny. Under the support of short resource, scrap tungsten prices has been hold relatively, but small transaction volume has been realized. Scrap tungsten suppliers’ attitude becomes more cautious and more willing to wait and see. Chinatungsten Online predicts scrap tungsten prices will keep steady generally but falling feebly.

Tungsten Mining (ASX:TGN) has followed up yesterday's Initial Public Offering on the ASX with the announcement that drilling has commenced on its flagship Kilba Tungsten Project in Western Australia. 

Tungsten says it is concentrating on rapidly evaluating and developing the site, which hosts a high grade scheelite deposit with potential to support a mining project. 

The diversified miner holds a 100 per cent entitlement to a mining lease within the Kilba, and has completed the first phase of its drilling program, comprising 8 diamind core holes. 

Tungsten says the drilling program, alongside its admission to the ASX, represents a significant milestone towards becoming a developer. 

Tungsten Mining listed on the ASX yesterday, closing the day at $0.205.

Core tips: The need of sodium tungstate remains weak, transaction prices are running at low level while few deals can be seen in tungsten carbide market.

Situation of tungsten concentrate market is that raw material traders are not eager to ship and the quotation is under restriction. Prices of individual tungsten products from downstream reduce by lower purchasing cost. The need of sodium tungstate remains weak, transaction prices are running at low level while few deals can be seen in tungsten carbide market, and the prices focus on ￥270.00/kg. The overall tungsten concentrate prices keeps falling, and some traders hold low expectation toward tungsten concentrate market in near future.

Sergei Belousov and his colleagues at Moscow’s Kintech Lab in collaboration with scientists at the GE Global Research Center in New York state have discovered an application for photonics crystals that can improve light emitting efficiency of tungsten. This may lead to a complete redesign of the light bulb at we know it.

Belousov and his team wanted to find out whether a nanostructure of tungsten can be engineered to create a photonic visible light-emitting infrared light. The team studied the theoretical properties of nanoscopic tungsten log piles and spheres embedded in another medium. They tested their data after creating a tungsten photonic crystal to measure the amount of emitted light occurring at different frequencies. What they discovered is that the structure emits less infrared light while having 15% efficiency – much higher than standard bulk materials.

Why is this important? Belousov and team’s research indicates improvements on the technology are possible. However, more research and testing are needed to determine whether the use of tungsten in light bulbs can achieve widespread use. Compact fluorescent bulbs match the light output of a 100 Watt tungsten bulb using less than 30 Watts, and LED bulbs can by less than 20 Watts. Belousov and his team may have their work cut out, but they believe they have a chance.
