| titleOfInvention | Improvements relating to the Manufacture of Titanic Acid. |
| abstract | 11,964. Matthews, D., and British Aluminium Co. June 8. Titanic acid.-A suitable bauxite, containing titanic acid, is finely ground, sifted, and then gradually stirred into sulphuric acid of 100‹ Twaddell contained in a circular wooden tank a lined with lead. The mixture is boiled by a steam coil b until it becomes pasty. Water is added, and the insoluble matter allowed to settle. The solution of aluminium and iron sulphates is siphoned off to the lead-lined wooden tank c, where it is diluted to about 50‹ or 60‹ Twaddell, and boiled by a steam coil d, whereby any titanic acid present is precipitated. After cooling and settling, the solution is run into an open evaporator e heated by a steam coil e<1>, and is run off into troughs k for crystallization. The cake is broken up into blocks by means of partitions in the troughs. The titanic acid from the tanks a, c is led to a small lead-lined tank f, in which it is boiled, by means of a steam coil g, along with strong sulphuric acid. Titanium sulphate forms, and is extracted with cold water. The solution is run through a filter h to a precipitating-tank i, which is heated by blowing in steam through a pipe j. Sodium carbonate is added to neutralize the free acid, and, if necessary, the iron is reduced to the ferrous state by treatment with sulphurous acid. Boiling is continued until all the titanic acid has separated out, the liberated sulphuric acid being neutralized at intervals. The titanic acid is then filtered, washed in a press, dried, and finally calcined in a small retort at a high temperature. |
