If the tailings were exposed to the surface environment, by the influence of physical and chemical weathering, the harmful materials such as Pb, Zn, Cd and As would enter into the water and soil through the process of dissolution, leaching and so on.
Dachang ore-field of Guangxi is the important raw materials production base for Sn, Sb, Pb, Zn and other nonferrous metals mineral resources, and the ores mainly occurred in the Devonian and Triassic carbonate strata.
Materials and methods Organization of the Text The two tailing samples collected from Changpo and Lutang reservoirs of Dachang were named as A and B respectively.

Conjoint analysis was used to analyze how the attributes such as the brand, the price, the raw materials, the environmental certification and the fluorescent additives of the rolling paper affect its purchase on the basis of the data from a survey among the consumers in Changsha.
It was based on those attributes influence most to consumer preferences.On the basis of survey from consumers, analyzed on literature concerning rolling paper,and consulted from papermaking enterprises on information of paper attributes,the attributes of brand, price, raw materials, environmental certification and fluorescent additives were selected for investigation.
After all kinds of papermaking raw material were in detail, many consumers had changed their view of regenerate pulp, as the data showed that the part-worth of regenerate pulp was 0.177, more higher than other two materials.

The spent Li-ion battery contains not only LiCoO2 as anode material but also other materials, such as lithium cobalt oxide, lithium hexafluorophosphate, organic carbonate, polyethylene, carbon materials, copper foil and aluminum foil and so on[1,2,3].
The broken materials were treated in ultrasonic field for 10 min.
The pretreated materials were mixed with water, H2SO4 and Na2SO3, and then were tested under the optimal condition.
Fig. 3 Effect of temperature on leaching rate Fig. 4 Effect of Na2SO3 adding amount on leaching rate In the experiment, the electrode materials are taken out from four pieces of spent lithium-ion battery as the raw materials.
