Potash Feldspar Recovery Process - 911 Metallurgist

2017-6-29  Over 95 pct of the Fe2O3 was removed by this process. The potash feldspar concentrate met the specification for electrical insulators, except that the soda content was below the 2.0 pct minimum. This deficiency could be remedied by blending the feldspar concentrate with soda feldspar, which is more abundant and cheaper than potash feldspar.

2015-9-10  From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percentmoisture. A rotary dryer is then used to reduce the moisture content to 1 percent or less. Rotary dryers arethe most common dryer type used, although fluid bed dryers are also used. Typical rotary feldspar dryers arefired with No. 2 oil or natural gas, operate at aboutE C 230(450E F), and have a retention time of 10 to 15minutes. Magnetic separation is used as a backup process to remove any iron minerals present. Followingthe drying process, dry grinding is sometimes performed to reduce the feldspar to less than 74 µm (200 mesh)for use in ceramics, paints, and tiles. Drying and grinding are often performed simultaneously by passing thedewatered cake through a rotating gas-fired cylinder lined with ceramic blocks and charged with ceramicgrinding balls.
