| Abstract: | Sodium polytungstate is a new inorganic heavy liquid with no toxic compounds and no odors. Solutions with densities ranging from 1.0 g/cm 3 to 3.1 g/cm 3 can be prepared. It is easily diluted, has excellent stability, a high recycling rate, and is convenient and safe. Sodium polytungstate has been used to separate zeolites and clay minerals with success. This paper describes in detail the preparation and recycling of sodium polytungstate, the method of separation of the Jinyun zeolites and associated clay minerals, and an outlook on the future application of sodium polytungstate. |
| Keywords: | Sodium polytungstate heavy liquid fine-grained minerals zeolite separation and purification |
