| titleOfInvention | Acid leaching technology for eroding silicon, preserving iron and removing phosphorus in high phosphorus oolitic hematite |
| abstract | The invention discloses an acid leaching technology for eroding silicon, preserving iron and removing phosphorus in high phosphorus oolitic hematite. The technology comprises the steps as follows: 1, the high phosphorus oolitic hematite is subjected to mineral separation with a conventional mineral separation process so that ore pulp of rough iron concentrate is obtained, and a mass percentage concentration of the rough iron concentrate in the ore pulp is adjusted to 50-70%; 2, the ore pulp with adjusted concentration is added to an agitator, technical hydrochloric acid, an iron preserving agent and a silicon eroding agent are added to the agitator, and agitation leaching is performed for 15-45 min; and 3, filtration is performed, so that a filter liquid and a filter cake are obtained, and the filter cake is low-phosphorus iron concentrate. According to the acid leaching technology, the technology route is simple, the production cost is low, the operation is simple, the energy consumption is low, and the ore adaptability is high; and with the adoption of the acid leaching technology, the iron grade of the rough iron concentrate can be improved, the iron recovery rate in a leaching process can reach 90-95%, and the low-phosphorus iron concentrate with an iron grade no less than 60% and a P2O5 content not higher than 0.15% can be finally obtained. |
