Rio Tinto goes ahead with $5.3 billion expansion of Oyu Tolgoi


In a fresh sign that the downturn in the resources industry may be finally over, mining giant Rio Tinto (LON:RIO) and its Canadian affiliate Turquoise Hill (TSE:TRQ) have signed off on a $5.3 billion expansion of their massive Oyu Tolgoi copper and gold mine in Mongolia.

The decision ends a three-year stalemate and political tension over revenue sharing and the foreign role in Mongolia’s mining sector.

Oyu Tolgoi’s development, set to cost about $400 million more than previously thought, will begin within months, the companies said. First production from the underground expansion is expected by 2020, when a shortage of copper is tipped to emerge.

Rio Tinto comapny as miner changed the world copper mateial condition , also it will drive the upper stream products market ,like wear resistant ceramic  market. alumina ceramic lining is mainly used for mining machinery wear protection . Chemshun Ceramics as wear ceramic liner manufacturer professionally solve mineral handling system wear damage with 92% or 95% Al2O3 high alumina ceramic tiles or pipes.contact email : office@chemshun.com

What are the characteristics of abrasion-resistant ceramic tiles?

What are the characteristics of abrasion-resistant ceramic tiles?  Abrasion-resistant ceramic tiles are widely used in many projects, in the pit furnace is also built with a wear-resistant ceramic tiles, wear-resistant ceramic tiles not only to fire resistance, high temperature requirements, but also to wear requirements, Introduce the impact of wear-resistant ceramic tile wear-resistant factors which have! Abrasion resistance of  abrasion-resistant ceramic tiles  depends on the composition and structure of wear-resistant ceramic tiles. When the abrasion-resistant ceramic tiles are composed of dense polycrystals composed of single crystals, the wear resistance depends on the hardness of the mineral crystals. High hardness, high wear resistance of the material. When the mineral crystals are non-isotropic, the grain size is small and the wear resistance of the material is high. When the material from the multi-phase composition, the wear resistance of the material with the bulk

What are interlocking wear-resistant ceramic tile liner ?

  The shape of ordinary wear-resistant ceramic tiles is a square sheet structure, and they are arranged in rows and columns. There are linear seams between the rows and columns of wear-resistant ceramic sheets. The linear seams along the direction of fluid flow are A smooth fluid scouring gap is formed.      In addition to the normal wear of the fluid on the surface of the wear-resistant ceramic sheet, the erosion gap becomes a breakthrough door for the fluid to wear the side of the ceramic sheet. Under the long-term erosion of the fluid, the seam will gradually widen and the degree of wear will become more and more serious. , the change of connection affects the service life of the wear-resistant ceramic sheet, which in turn affects the protection effect of the anti-wear parts. After this kind of wear-resistant ceramic sheets are pasted, the adjacent ceramic sheets do not have an interlocking effect with each other. The pasting is not strong during installation or they are easy to fal

Development of Ceramic Materials

图片
Ceramic is the oldest material, and it is the first chemical product made by human conquering nature. It appeared much earlier than metal materials. It is one of the symbols of human civilization and an important research object in the history of human civilization. For a long time, the development of ceramic materials relies on the teaching of craftsmanship. The products are mainly household utensils, building materials (such as bricks, glass), etc., usually called traditional ceramics. Due to the development of materials science, people have a deep understanding of the relationship between material structure and distribution. They can successfully control the chemical composition and micro - structure of lattice materials and successfully develop ceramic materials with different properties. For example, high-temperature structural ceramics and various functional ceramics (electronic materials, optical fibers, sensitive ceramic materials, etc.) have been more and more widely used, an
