Production method for titanium-rich material

[0066] Take 500g titanium concentrate (TiO 2 The grade is 47.5%) and 240g of sodium hydroxide are mixed and placed in the reactor, the control melting reaction temperature is 480 ° C, the melting reaction time is 50min, and sodium metatitanate (Na) is obtained after melting and decomposing. 2 TiO 3 ), sodium silicate, sodium manganate, sodium aluminate, sodium chromate and mixed solid phase of iron, calcium and magnesium oxides.

[0067] The obtained sodium metatitanate (Na 2 TiO 3 ) The mixed solid phase was fully washed with water, and the washing temperature was 25 °C to obtain a solid-phase hydrated sodium titanate (Na 2 O 2TiO 2 ·xH 2 O), solid phase iron, calcium, magnesium oxides and dilute lye (NaOH dilute solution containing silicon, manganese, aluminum, chromium impurities), after filtering and removing the dilute lye, carry out re-selection to remove most of iron, calcium, Magnesium oxide.
