The coarse product of the flotation test can be directly filtered. If the product is very fine or contains a lot of mud, it is difficult to filter. At this time, it can be directly placed on a hot plate or an oven to evaporate. It is also possible to add a coagulant, such as adding a small amount of acid or alkali, alum, etc. to accelerate the sedimentation, extracting the clear liquid and drying it. dry. During the drying process, the temperature should be controlled below 110 °C; if the temperature is too high, the sample will be oxidized and the result will be scrapped. For example, when the sulfide mineral is at a high temperature, S oxidation becomes SO 2 volatilization, resulting in sample grade change. After the flotation product is dried and weighed, it must be shrunk and ground for chemical analysis. The particle size of the sample for chemical analysis should be less than 100 mesh or 150 mesh.
