Data Mining for ERW Welded Tube Scheduling Rules Based on Decision Tree ZhaoNing a, Dong Shaohuab , Tian Qingc Mechanical school of university of science and technology Beijing 100083, Beijing China azhning@sina.com, bdsh-dle@me.ustb.edu.cn, ctianqingycy@163.com Keywords: Data mining, Scheduling rules, Decision-Tree, Welded tube Abstract.
Data mining for welded tube scheduling rules based on decision tree The strip is the raw material of ERW welded tube production whose technological process has three main stages: (1) Vertically trim product line of wide strip steel to obtain appropriate band steel
Combined with related thesis [7] [8] and present condition of enterprise, order attribute of selection includes the following aspects: Absolute remaining sorting time (ARST): in the project, ARST refers to all the time from the raw materials received to finishing warehousing.

The plastic deformation resistance of the material is one of the key factors that directly affects the safe operation of equipment and insurance of the plastic deformation during thermal processing[2].
Strengthening (hardening) and softening (recovery and recrystallization) of metallic materials takes place in the process of plastic deformation.

Some stable complex substances can be formed by a chiral stationary phase (CSP) and isolate material.
When hydrogen bonding, dipole - dipole interactions and π-π seize dominant position, the isolate material can be separated from CSP.

Recovering Gold from a Gold-bearing Pyrite by flotation and chemical process Qing Li1,a,Baoliang Ge1.b,Jie Liu1,c,Chao Zhu1,d 1Faculty of Land Resource Engineering, Kunming University of Science and Technology, Kunming 650093, China a735406880@qq.com, b411977506@qq.com c527245266@qq.com,d231652466@qq.com Keywords: gold-bearing pyrite; flotation; cyanide leaching; regrinding Abstract: The ore assays 2.5g/t Au, 23.4% S and 56.6% Fe.
The gold can be found as metal or alloy(silver，copper, bismuth), as a distinct mineral in combination with tellurium ,or it can be contained in carbonaceous material, pyrite, marcasite, arsenopyrite and siliceous gangue[1], which are difficult to recover.
Materials and Methods Representative ore samples were taken from Sichuan, China.
