Ecological treating method for blast furnace slag containing titanium

Abstract

The invention relates to biology process method for titanium contained blast furnace slag that the TiO2 is over 16.03% titanium contained as raw material. After crashing, magnetic separation, pulverizing, and baking for 1 hour under the condition of 800 degree centigrade and strong magnetic field of 0.8-4.0, tesla cooling naturally, the ZnO, CeO2, or AgCl could be mixed in it. The invention has simple process, low cost and could be used in kinds of fields.

Description

technical field

[0001] The invention relates to a treatment method for slag produced by blast furnace smelting pig iron, in particular to an ecological treatment method for titanium-containing blast furnace slag produced by blast furnace smelting ilmenite. Background technique

[0002] At present, there are a large number of research reports on the treatment and application of titanium-containing blast furnace slag at home and abroad.

[0003] The ilmenite ores used in foreign blast furnace smelting generally contain TiO due to their low titanium content. 2 Not more than 3 to 4%, the TiO contained in its blast furnace slag 2 Generally, it is lower than 10%. Therefore, foreign titanium-containing blast furnace slag is similar to ordinary blast furnace slag, and does not require special processing in utilization, and is completely utilized as ordinary slag.

[0004] my country has relatively large reserves of vanadium-titanium magnetite, which has been proven to be 6.19 bill...
