Continued weakness in demand for tungsten terminal, guidance prices also fell, buyers were continued stalemate, tungsten concentrate market this week stable and slightly lowered. Downstream tungsten smelting enterprises product unsalable, production operation, but with the current material tungsten prices hit bottom, manufacturers want hunters buy tungsten, tungsten market leads to low increase in inquiries, but the actual transactions remains weak, it is expected that the recent market mainstream price still lower risk, but limited range.

Shippers hand inventory costs are higher, the current price of shippers will ship is still low, shippers much hope in the traditional peak season "golden nine silver ten", the current difficulties in the capital turnover and forced to small unless the goods now, hold the goods market, under the support of tungsten concentrate prices decline, the mainstream.

Since August the tungsten concentrate agency guidance price decline, tungsten, business mentality remains in the doldrums, waste tungsten market atmosphere has been deserted, low-cost resources to further increase. Because the mind differences, businessmen price slightly high price confusion, poor widened. Expected short-term waste tungsten market or remain vulnerable to run.

The weakening of waste tungsten prices stable. At present, the waste tungsten bit is not including tax price concentrated in the mainstream 188-189 yuan /kg, domestic waste tungsten blade 168-170 yuan /kg, imports of scrap tungsten blade 178-180 yuan /kg, scrap wire drawing die 1780-180 yuan /kg. Waste tungsten grinding material 30-40 traders purchase price concentrated in the 1.45-1.5 yuan / degrees, 50-70 degrees concentrated in the 1.55-1.7 yuan / degrees, 70 degrees or more concentrated in the 1.7-1.75 yuan / degree.

Plymouth Minerals has reported bullish assay data from multiple prospect areas within its brownfield Morille Tungsten Project in Spain. Early work programmes are indicating potential for annualised output of 100,000 MTU’s of ATP valued at US$38.8 million.

A first pass drilling programme seeking very shallow tungsten values across 6 of 16 historic mines contained within the Morille Project area may exceed earlier conceptual resource targets of 4 – 11 million tonnes grading 0.25% - 0.5% WO3. Historic tin production (poorly recorded) on site as well, but main economic value is tungsten.

The Morille Project area was historically mined by small groups of undercapitalised miners who typically operated within small tenements of typically less than 10 hectares and at very shallow depths. Production data show that that Morille produced high grade tungsten concentrate that was well received by global markets.

First pass drilling is indicating that historic mining boundaries were constrained by small tenement holdings as well as limited access to capital and that mineralisation extends well beyond mined areas.

Peer group tungsten miners and developers that are proximate to Morille are reporting cash operating costs that are as low as US$120 –US$130 per Metric Tonne Unit “MTU” of Tungsten Paratungstate (APT) or WO3, which currently sells for US$388 per MTU. This has resulted in current operating margins that are as high as 70% and feasibility studies for new projects with Internal Rates of Return as high as 52%.

High margins that are targeted are being driven by the strategic nature of tungsten and growing demand that is currently controlled by China with 85% of the market.

High margins at Morille will also be driven by the shallow nature of the resources and the simple and low cost gravity methods that are needed to produce high quality tungsten concentrate.

Tungsten market: Tungsten Association guidance prices lower, the business mentality downturn, although very few transactions, tungsten overall price stability, but the purchaser demand greater intensity, clinch a deal the price lower actual, powder market high price cut, price closer to the low. Sodium tungstate market demand remains in the doldrums, with tungsten Association guidance price declines, Minmetals has not buy in large quantities, this week the sodium tungstate inquiry lowered again, although the smelting manufacturers cut and dimension stability quote, but the actual transactions is still slightly lower. The latter is expected price or have tungsten products slightly down.

Tungsten products prices dropped significantly. At present, tungsten powder and tungsten carbide market the actual transaction price of mainstream concentrated in between 253-255 yuan /kg, fell 2-3 yuan /kg. Because Ganzhou tungsten co guidance price cut, tungsten, business mentality also weakened, powder market high price cut, price closer to the low.

Steelmaking with the price dropped to 275 yuan /kg, high pure tungsten bar 295 yuan /kg, fell 3-5 yuan. Tungsten electrode polished rod price has remained around 405 yuan /kg. Powder manufactured goods prices fell, prices have to fall. Expected short-term tungsten products prices or will continue weakening trend.

Sodium tungstate market demand remains in the doldrums, with tungsten Association guidance price declines, Minmetals has not buy in large quantities, this week the sodium tungstate inquiry lowered again, although the smelting manufacturers cut and dimension stability quote, but the actual transactions is still slightly lower. According to the current understanding of 96 sodium tungstate mainstream cash prices in the 12.4-12.5 yuan / ton near, part processing or slightly lower.

Ammonium paratungstate market continued to slump, price stability test, the cash price of the mainstream in 16.2-16.3 yuan / ton, compared with last week, down 1000 yuan / ton. Analysis of the causes of the ammonium paratungstate market down: one is the terminal consumption ability is poor, resulting in ammonium paratungstate downstream demand is difficult to release, ammonium paratungstate market demand not flourishing; two is the latest August tungsten Association guidance prices down again, the business mentality of weakness, high price decline. Is expected in the short term the ammonium paratungstate price or in the 16-16.3 yuan / ton.

Tungsten market: yesterday Minmetals guidance prices flat, Ganzhou tungsten co guidance prices down slightly as expected, 65 degree black tungsten from 110000 to 107000, closer to the actual market price 105000, because the two big institutions offer the disagreement continued weak demand downstream, Shang Jiamu, before the main wait-and-see, late funds hold the goods business shipment or slightly increased, expected short-term tungsten price stability and fall.

Yesterday the Minmetals Nonferrous and Ganzhou tungsten co published guidance price is different, Minmetals flat 65 degree black tungsten concentrate bid to 110000 yuan / ton, Ganzhou tungsten co down 3000 to 107000 yuan / ton, the two price is still higher than the actual price, in this price spot market sale does not ship. It is understood, now a 65 degree black tungsten concentrate 105000 yuan / ton are difficult to sell, 65 degree white tungsten concentrate even now 103000 yuan / ton low price.

The two institutions offer the differences, continued weak downstream demand, businesses at present mainly wait-and-see, late funds tense shippers shipping intention or slightly increased, the short term price of the tungsten vulnerable, there is still risk small fell.

Hardide Coatings has supplied its Hardide T nano-structured tungsten carbide coating for a new range of trunnion-mounted ball valves for the UK energy sector.

The ‘Phase’ range includes numerous variations of soft and metal seated side entry ball valves, used for the safe isolation of pipeline production and process equipment. These valves are often used in erosive operating environments, so the new valve required a durable protective tungsten carbide coating. The Phase range comes in both metal to metal and soft seated options which posed additional considerations.Metal to metal seated valves often suffer wear by erosion when there is particulate in the process fluid. Most ball valves are soft seated, but wear can also cause scratches and resultant leakage.

Heap & Partners selected Hardide-T for use in the range, particularly in the smaller diameter valves, for several reasons, including the inherent hardness of Hardide-T, at 1100 to 1600 Hv with a typical tungsten carbide coating thickness of 50 microns. Hardide-T is produced in a gas-phase CVD (chemical vapour deposition) process.

“The Hardide coating achieved excellent results, meeting all the required leakage rates and delivering consistent results on various substrates,” said Peter Burnett, business development manager at Heap & Partners. “We also chose to partner with Hardide Coatings as we worked with the team previously on a project in the nuclear sector to tackle a corrosion issue and carry out re-engineering of valves.”

Corrosion resistance

Heap & Partners has now utilised Hardide-T on many ball valve applications for both oil and gas and nuclear clients. There have been no wear issues since employing the tungsten carbide coating and it has provided protection from erosion. In some cases the Hardide coating has also improved the corrosion resistance of the base material.
