Изобретение относитс к способам получени пигментной двуокиси титана, а именно к способам осветлени сернокислых растворов титана, получаемых при переработке титансодержащего сьгрь , в Частно- сти тлтановых. шлаков.The invention relates to methods for producing titanium dioxide pigment, in particular, to methods for clarifying sulfuric acid solutions of titanium obtained by processing titanium-containing gold, in particular tltanic. slags.
Известен способ осветлени растворов сернокислого титана, получаемых при переработке титансодержащего сырь , например титанового шлака, путем отстаивани их в присутствии поверхностно-активного вещества (ПАВ). В качестве ПАВ используют проксанол в виде 0,2-1%-ного раствора из расчета 45-55 мг, счита на сухое вещество , на 1м суспензии.There is a known method for clarifying solutions of titanium sulphate obtained during the processing of titanium-containing raw materials, such as titanium slag, by settling them in the presence of a surfactant. As a surfactant, proxanol is used in the form of a 0.2-1% solution at the rate of 45-55 mg, calculated on dry matter, per 1m of suspension.
Однако дл данно1 о способа характерны невысока скорость отстаивани (15см/ /час), а также относительно высокое содержание шлама в осветленном растворе (1,27 г/л).However, this method is characterized by a low rate of settling (15 cm / / h), as well as a relatively high content of sludge in the clarified solution (1.27 g / l).
С целью повь(шени скорости отстаивани растворов сернокислого титана и снижени содержани шлама в осветленном растворе, предлагаетс в качестве ПАВ использовать оксифос Kii-6 (простой эфи2 In order to increase the speed of settling titanium sulphate solutions and reduce the sludge content in the clarified solution, it is proposed to use oxyphos Kii-6 (ether 2

фосфорной кислоты). При этом ПАВ примен ют в виде 0,2-10%-ного водного раствора из расчета 5О-75 г вещества на 1 м раствора сернокислого титана.phosphoric acid). In this case, the surfactant is applied in the form of a 0.2-10% aqueous solution at the rate of 10 ~ 75 g of substance per 1 m of titanium sulphate solution.
Указанное отличие повышает скорость отстаивани раствора до 40 см/час и снижает содержание шлама в осветленном растворе до 0,96 г/л.This difference increases the rate of settling of the solution to 40 cm / hour and reduces the sludge content in the clarified solution to 0.96 g / l.

The solution is settled for 18 minutes. Then the ½ volume (free fall zone) is decanted and the solids content is determined in the decanted solution. The rate of settling was 4 cm / h, the solid content in the clarified solution was 0.96 g / l. 3 The subject matter of the invention 1.
