Developed a test using column flotation device, this experiment device in the structure designing considerate multifunctional traits, realizing continuous and respectively working. In the testing platform, installing two diameter vertical and inclined floatation column, so the device can complete roughing, selection and sweep the election testing. On researching the inflatable way, designing and testing two kinds of inflatable devices, one is jet, the other is sand core type. And testing three kinds of into ore ways, conical nozzle atomizer, atomizer grid and bar nozzle device. Through a series of contrast testing, making useful testing data, the testing provide the basis for designing the floatation column.
