It can be seen that these methods consume too much time. When an abnormal situation is detected, the actual production has passed for several hours. Therefore, these methods have poor guidance on production indicators and are likely to cause metal loss, thereby affecting the normal production of the concentrator. , causing a loss in production

The invention discloses a method for judging the content of a magnetic substance. The method comprises the following steps: acquiring a sample by utilizing a container with a preset capacity; weighing the weight of the sample; obtaining the concentration of the sample and the dry weight of the ore according to the weight of the sample and the corresponding relation between the weight of the sample and the concentration; performing magnetic separation on the sample, and weighing the weight of a magnetic substance obtained by magnetic separation; and calculating the content of the magnetic substance according to the weight of the magnetic substance and the dry weight of the ore. According to the method for judging the content of the magnetic substances, the condition of metal loss in the tailings in the production process can be quickly judged, quick adjustment in the production process is facilitated, metal loss is reduced, the recovery rate of metal is increased, and production benefits are increased.
Description
technical field [0001] The invention belongs to the technical field of magnetic mineral beneficiation, in particular to a method for judging the content of magnetic substances. Background technique [0002] At present, in the production process of iron ore concentrators, the detection of magnetic substances mainly depends on the laboratory testing of total iron and magnetic iron. In this case, it takes at least 2 hours for sampling and testing, or using laboratory magnetic separation tubes for separation. Then carry out the total iron assay and calculate the magnetic iron. In this case, the sampling, experiment and assay time will take at least 3 hours. It can be seen that these methods consume too much time. When an abnormal situation is detected, the actual production has passed for several hours. Therefore, these methods have poor guidance on production indicators and are likely to cause metal loss, thereby affecting the normal production of the concentrator. , resulting...
