Enhanced column bioleaching of copper sulfides by forced aeration Mingqing Huanga, Yiming Wangb*, Shenghua Yinc, Aixiang Wud School of Civil and Environment Engineering, University of Science and Technology Beijing, Beijing 100083, P.
From then on, forced aerations have been applied in series of bioleaching practices worldwide and regarded as a key technology to enhance the bacterial leaching of sulfides[7-9].
Materials and methods Mineralogy.
When the aeration rates are higher than 60 L/h, Cu leaching rates increase dramatically on day 4~20.These phenomenon attributes to mineralogy of the raw materials.

Introduction At present, the technique of recycled concrete is the subject which every country cares about together and becomes one of the hottest spots and frontierest problems in engineering and academia[1-5].Recycled concrete is the concrete which takes abandoned concrete debris removed from the old buildings as coarse aggregate and mixes with cement mortar.
As the research and application being in-depth, recycled concrete has been applied to more and more structures as a common kind of building material.

The normalized peak contact pressure and the contact length along the male sides are numerically evaluated. 1 Introduction Polygonal contacts are encountered in keyless polygonal joints, employed as an alternative mechanical coupling to keyed joints in the transmission of torque between two shafts, [1, 2].
In [5], on the basis of engineering judgment, it is assumed that a) the pressure profile is triangular; b) one half of the length of each side of the polygonal profile is in contact, whereas separation takes place in the remaining side portion.
A linear elastic material with elastic constants typical of steel was adopted.
