Vacuum crystallization of titanium dioxide

In the process of titanium extraction from lime nite， a large amount of ferrous sulfate needs to be crystallized out from the mineral solution made by dissolving the limonite in acidic water.The objective of vacuum crystal l zation is to cool the mineral solution for the ferrous sulfate to precipitate out.Under vacuum and decompression， the boling point of the mineral solution lowers to lead to a boiling and the solvent evaporates.In the vaporization， a large amount of heat is absorbed， so that the solution is cooled quickly and ferrous sulfate crystals precipitate out.
