Introduction Copper is one of the earliest human discovery and use of metal, copper and its alloys, good electrical conductivity and thermal conductivity, corrosion resistance, easy processing characteristics and are widely used in metal material consumption after steel and aluminum, with a wide range of applications in the electrical industry, mechanical industry, chemical industry , defense industry and other sectors[1].
For a single sulfide copper ore, because the copper minerals and gangue minerals floatability difference is bigger, So is the better flotation, but is restricted by the factors of ore oxidation rate, structure and tectonics.
It use Pharmaceutical processing to change their conductive properties, and help to improve the separation efficiency.

The characteristics of tencel fiber in addition to the traditional fiber moisture absorption, elegant thereof, but also has great strength and the unique characteristics of the original fibrosis, mechanical friction, can become a style of peach skin velvet, in general, the advantages of tencel fiber, in addition to the above characteristics, its comfortable, soft, smooth, cool, and good vertical etc. 1.2Rose protein fiber application in textile and garment industry Rose protein fiber is to utilize renewable green natural plant fiber, modification of cellulose fiber, is a kind of degradable environmental protection new type of fiber.
Knitted products can reflect the stand or fall of elastic fiber, the structure of the knitting products is the main reference data of the length of the coil, because the length of the coil can affect the density of the coil, the fabric handle, elasticity, and the volume of knitted fabric, in addition, the factors influencing the quality of knitted fabric, and the tension of yarn.
PPT fabric because of its good dyeing properties, so often made into colored yarn, color fiber, before knitting, in actual production, the PTT fabric with printing process and grey fabric dyeing, PTT fiber is often used in atmospheric dyeing, because most of disperse dye stability at low temperature is stronger, therefore, the PPT dyeing range is wide, the PH range is between 4 to 10. 2.Conclusion As new type fiber textile raw material, has excellent performance and health care performance, embodies the people to the pursuit of life, more is recognized as the green environmental protection material on ecological environmental protection, protect the ecological environment.

The field enhancement factor on the tip can be as high as 1000[28].
The better sensitivity of this kind of PDMS composition depends on the mechanical properties of the samples.

The heat partition factors between the tip and chip are solved by using the inverse heat transfer analysis, which utilizes temperature on the carbide tip's surface measured by infrared as the input.
Fortunately, the temperature and cutting speed affected on BUE formation are relatively well defined, and can be controlled.
Sreejith et al. [16] showed the wide difference in thermal properties of the fiber and matrix material and also the relatively poor thermal conductivity of composites make it rather difficult to adopt any of the unconventional technique for machining the polymeric composites.
Table 2 shows some of the physical and mechanical properties of GFRP prior to carrying out the cutting experiments.
This model can be extended to on-line control domain in addition to the factors of time and thermal effect.

However, one of the main requirements to extend the design life is to ensure the integrity of the vessel itself, for which it is required to know the evolution of material properties of the vessel.
STP notched specimens: Master Curve approach In the last few decades, the development of methodologies such as Master Curve [2] has allowed a direct estimation of fracture properties for vessel steels to be carried out.
In eq. (7) “dn” is a parameter that depends on tensile properties and can be obtained from [10].
The tensile properties required by the analysis have been calculated using eq. (1) to (4)

A plethora of factors need to be considered while employing such design methodology.
It is equivalent of changing the viscosity index of the MR fluid, which affects the yield behaviour of the MR fluid.
The properties of these materials are given in Table 2.

The performance of asphalt directly affects the mechanical properties and performance of asphalts mixture.
Group 17 is a comparing group that is for the influence factors on the test results.
Also the DSR and BBR test should be done to study the rheological and mechanical properties change after salt freezing cycles.

Temperature is a common changing factor that is easy to measure and regulate and thus serves as a common regulating factor for intelligent biomaterials.
Some existing biological materials are based on temperature changes to transform the physical or chemical properties of the material itself to achieve the desired intelligent control.
A single material is often insufficient in properties such as mechanical strength or range of temperature sensitiveness.
Other nanomaterials that are sensitive to infrared and near-infrared light have been developed, but long-wavelength light will cause the temperature to increase, thereby affecting the structure and function of the material.
pH-sensitive materials generally contain groups that are sensitive to H+, and will change their structure and properties with changes in response to the external pH.

Their main drawback is their poor dynamic properties, which limits their range of possible applications, e.g. in control systems.
The breadth of the zone and pressure losses within it depend on random factors and cannot be described mathematically.
The linear part of the model describes the dynamic properties of the valve, and the non-linear part describes its static properties.
Analysis of dynamic properties of the valve can be limited to the linear part.
Research to begin soon will focus on synthesising an actuator that would minimise the valve’s hysteretic properties.

It has been reported that the irregular particles have larger conduction losses due to large surface area, consequently affects the microwave absorbing properties [4].
