Production of purified iron chloride by a vacuum process in the manufacture of titanium dioxide |
| abstract |
This invention provides a process for the recovery of purified ferrous chloride resulting as a by-product during the production of titanium dioxide by the chloride process. The process involves a two-step cooling of a filtered solution containing ferrous chloride and other material in a manner to crystallize the ferrous chloride as a pure product. Such product can then be sold commercially including to companies involved in the waste water treatment business. |
