Introduction Metal bonded superabrasive tools are extensively used in precision machining of hard brittle materials because of their high hardness, thermal resistance and long tool life [1].
The special fillers, which can be metal, metal oxide or non-metal oxide materials, are added in the metal bond material.

Materials and Methods Sample Selection As a heavy industry, thermal power generation consumes much coal, and emits much carbon dioxide, nitrogen oxides, sulfur dioxide, etc.
It is very possible to gain win-win situation of these two performances, if the listed corporates tend to use advanced materials and technology and optimize environmental management strategy under the guideline of reducing, reusing and recycling principles.

In the meantime, the canopy can be optimized because its biggest stress is far smaller than the allowable stress of the material.
Hydraulic support often determine its numerical parameters only by experience or limited prototype experimental spots in the traditional design and selection process.We can calculate the strength by the material mechanics knowledge, but the safety coefficient often get very large which caused hydraulic support frame bulky.
So, reducing weight is converted to reduce canopy's cross-sectional area, this paper use a objective function which canopy's section of the actual material area is the smallest.
(4) Type: -material bend limit, Mpa, -allowable safety coefficient, take 1.2, -the maximum bending stress of section, Mpa, Shear strength conditions:When the shear strength of this section is the maximum, we should check shear strength.Now test to shear stress in neutral axis place

Fluorite flotation of a fluorite-bearing Pb-Zn tailings Siqing Liua, Xiujuan Lib, Min Zhang c, Wanping Wang d Department of Mineral Processing Engineering, Kunming University of Science and Technology, Kunming 650093, China a647647@163.com, b497522449@qq.com, c 282179895@qq.com, d 578607690@qq.com Keywords: Pb-Zn tailings; fluorite; flotation; modifier Abstract: Beneficiation of a Pb-Zn tailings containing 44.98% CaF2 was conducted by flotation using sodium hexametaphosphate and new reagents S180.
Seventy percent of fluorite products were used as metallurgy and building materials.
In addition, fluorite is the only raw material for producing hydrofluoric acid [2], so the consumption of fluorite in chemical industry increases in recent years Fluorite deposit includes single and associated types with some accessory minerals such as Pb-Zn sulphides, W-Sn sulphides and pyrite.
