| titleOfInvention | A kind of method of comprehensive utilization of ferrous sulfate purification removal of impurities waste |
| abstract | The present invention relates to waste's reclamation fields, and in particular to a kind of method of comprehensive utilization of the ferrous sulfate purification removal of impurities waste in the production process using sulfuric acid method titanium pigment.It includes the following steps：(1) waste is acidified detaches to obtain synthetic rutile；(2) filtrate detaches through precipitation, roasts to obtain iron oxide red；(3) concentrating filter liquor obtained by a process dries to obtain ammonium chloride on.The present invention is comprehensively utilized using the ferrous sulfate purification removal of impurities waste in sulfuric acid method titanium pigment production process, realize the comprehensive utilization of solid waste and the promotion of value of the product, make the ferrous sulfate in sulfuric acid method titanium pigment production process purify removal of impurities waste to rise in value, by single solid waste, it synthesizes to obtain three kinds of chemical products by precipitation and separation, it is easy to implement, turn waste into wealth. |
