Tungsten consumption from other electronic and electrical applications, including electrical contacts, electron emitters and lead-in wires, is forecast to grow at 5.4% per annum through to 2018, more than double the overall trend.

The resistance of tungsten to wear and corrosion and its ability to withstand arcing make it a suitable metal for use in contacts and voltage regulators. Demand from these applications however is minor in term of volume, meaning by 2018 their share of demand would only be 2%.

This report seeks to examine the financial viability or otherwise of mining tungsten ore 10% and processing same into tungsten ore 65%. Processing and separation of the tungsten would be done in any of the processing plant stated in the body of the report.

The business would entail using mechanized method of mining to produce 250 tons per month of tungsten ore in which minimum of 25 tons of 65% tungsten would be extracted.

In the above projections 100tons of rocks with 10% tungsten content will give 10 tons of pure 100% tungsten which should translate to approx. 15 tons of 65% grade but putting recoveries and loss of material during processing and to allow for low expectations associated with mineral processing. We use a 10 tons of 65% grade in our estimates, possibilities are there that we might be able to achieve more than 10 tons.

The required start-up capital estimate of the business is N 64,000,000.00 and it would be funded from 30% equity N 19,200,000.00 and 70% loan N 44,800,000.00. the loan would be  used to finance our purchase and installation of the production plant and the working capital.

Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tungsten directly translatable to heavy stone.

Tungsten is a grayish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.

Tungsten（W）is a metal with a wide range of uses, the largest of which is as tungsten carbides in cemented carbides. Cemented carbides(also called hardmetals)are wear-resistant materials used by the metalworking, mining, and construction industries.

Tungsten metal wires, electrodes, and/or contacts are used in lighting, electrical, electronic, heating, and welding applications. Tungsten is also used to make heavy metal alloys for armaments, heat sinks, and high-density applications, such as weights and counterweights; superalloys for turbine blades; tool steels; and wear-resistant alloy parts and coatings.

Tungsten composites are used as a substitute for lead in bullets and shot. Tungsten chemical compounds are used in catalysts, inorganic pigments, and high-temperature lubricants.

Global tungsten demand has increased on average by 2.7% per annum since 2008, although estimates suggests that this will slow to 2.6% per annum in the years to 2018 as its direct use in lighting applications diminishes.

Representing 12% of total demand in 2013, tungsten used in lighting applications is forecast to decline by around 5% per annum in the year to 2018. the drop-off in demand is caused by the replacement of incandescent bulbs by fluorescent and LED bulbs in both industrial and domestic applications. On a positive note, however, these new lighting products require greater volumes of refractory tungsten alloys indirectly in their manufacture, boosting demand in the alloy sector.

The entrance angle of nozzle affects inner flow path abrasion directly. When the convergent angle of entrance is narrowing, the rate of wear will increase linearly. In addition, the bumps on the inner wall surface of the nozzle will also have a greater impact resistance against the sand-blasting, which expands the cracks on the surface and accelerates the abrasion of nozzle. Therefore, enhancing the fineness of inner wall can decrease the abrasion to some degree. Nowadays, many new materials appeared in succession, such as complex carbide, whose density and hardness is as good as tungsten carbide, but its lifespan is several ten times longer than tungsten carbide.

The diameter of nozzle entrance is determined by the flow and pressure. If we narrowing the exit diameter, the pressure and the flow velocity will become greater when the flux is constant so that the sand impact kinetic energy is enhanced and the abrasion of nozzle entrance is severer. Compared with nozzles with different convergent angle, as conical nozzle, the smaller convergent angle, the flow is more stable and the less loss of energy. In addition, lengthen the nozzle appropriately is beneficial for decreasing abrasion, which lengthen the path of the abrasive curve arriving.

Erosion from air at room temperature; the main purpose for the manufacture of filaments and high-speed cutting steel, hard mold, also used in optical equipment, chemical equipment.

tungsten ore dressing production line equipment from the jaw crusher, ball mill, classifier, magnetic separator, flotation machine, concentrator Crusher Machine and dryer and other major equipment components, with the feeder, elevator, conveyor can form a complete dressing production line. The tungsten ore dressing production line with high efficiency, low energy, high capacity, economical advantages. 

Tungsten, a metallic element, a refractory metal tungsten is rare. Steel is part of non-ferrous metal tungsten, is also an important strategic metal, tungsten ore in ancient times was called tungsten. W is a chemical element, is very hard, steel-gray to white transition metal. China is the Raymond Mill world’s largest country store tungsten, tungsten content in the crust is 0.001%. Tungsten Deposits are generally accompanied by granitic magma activity and the formation. Minerals containing tungsten are wolframite and scheelite and so on.
