In slicing a crystal bar into silicon wafers, an average about 40% of silicon would be loss due to the widths of slicing wires themselves. The fact that the silicon slurry is discarded as sludge or discarded after recovering silicon carbide particles causes a large waste of cost. If the silicon slurry (40% of silicon) could be recovered as the raw material for growing silicon crystal bars, the production cost would be lowered. The recovery method of silicon slurry according to the present invention could effectively obtain silicon raw material after removing impurities, which could recover the raw material used in solar crystals, further capable of increasing the silicon crystal production and lowering the cost.

A slidable mobile phone includes a main body, a sliding cover and a positioning device. The main body includes a first combining component and an upper casing. The sliding cover includes a second combining component and a lower casing. A first sliding part is provided on the first combining component, and a second sliding part and a pointing device by detecting the pressed direction are provided on the second combining component. The second sliding part is connected to and relatively slides along the first sliding part, and the pointing device by detecting the pressed direction is used for controlling the slidable mobile phone. The positioning device includes two magnetic elements which are provided on the first combining component and the second combining component, respectively.
