| titleOfInvention | Method for improving grade of magnetic concentrate by using reagent |
| abstract | The invention discloses a method for improving the grade of a magnetic concentrate by using a reagent. Fine fraction magnetic minerals can be easily mixed with impurities in the magnetic separation process to cause a low grade of the concentrate. By the method, dispersing agents such as sodium carbonate, sodium metasilicate, sodium tripolyphosphate, sodium thiophosphate or a mixture of the sodium carbonate, the sodium metasilicate, the sodium tripolyphosphate and the sodium thiophosphate, organic dispersing agents such as starch, humic acid, polyvinylpyrrolidone, polyvinyl alcohol, a polyvinyl alcohol homolog or a mixture of the starch, the humic acid, the polyvinylpyrrolidone, the polyvinyl alcohol and the polyvinyl alcohol homolog, or organic dispersing agents and a mixed dispersing agent of the organic dispersing agents are used for preparing a 5 to 30 weight percent aqueous solution, the using amount of the aqueous solution is 1 to 50mg/L, and mineral particles are dispersed in ore pulp and then are subjected to magnetic separation, so that the grade of the magnetic concentrate is improved, and the problem of complicated processes due to a low grade of the magnetic concentrate or requirements of flotation and reconcentration after the magnetic concentration is solved. By the method, extremely good magnetic separation effects on ferromagnetic mineral resources or low-magnetic mineral resources such as various iron minerals, chromite, iron pyrite, manganese minerals, wolframite, copper sulfide ores and copper oxide cobalt ores can be achieved. |
