Garnet sand 60 80 120 usually is used for water jet cutting. A water jet manufacturer or the abrasive supplier can assist the business to determine the right abrasive type and grade.All the gold is in the undissolved residue, and after washing thoroughly it is dried and fused. It still contains traces of silver, but is suitable for most purposes without further purification. The silver solution is diluted with water, the metal precipitated by the action of copper, and the solution formed worked up for cupric sulphate.Slow sand filters have a surface load of 0.1-0.2 m m hour. Continuous sand filters have a hydraulic speed of 5-10 m 3 m 2 hour. Effectiveness. Sand filtration is primarily used for the removal of suspended matter. The yield in this case varies between 50 and 99.99 , depending on whether support aids are used. In addition to suspended.Oct 17, 2005 Its oxide form, known as silica or quartz, is dirt-common.
