Advantages and disadvantages of separation-flotation method

Separation flotation is a method that combines pyrochemical treatment with flotation. For example, the segregation flotation of refractory copper oxide ore is to crush the ore to a certain particle size, mix it with a small amount of salt (..%) and coal powder (..%), and heat it to about 100 degrees Celsius with oxygen. Copper precipitates in the metallic state on the surface of the carbon particles. The roasted sand is cooled in oxygen isolation and then ground and flotated to obtain copper concentrate.

The biggest advantage of the separation and flotation method is that it can solve the problems of ores that cannot be processed by conventional mineral processing methods. It can comprehensively recover useful metals in the ores. For example, in copper ores, when the ore contains a large amount of chrysocolla cuprite and combined copper, or when it contains a large amount of slime, the flotation method of this type of ore often has very low indicators, while the segregation method is more effective. Effective. The segregation method can also process mixed ores of copper oxide ores and copper sulfide ores, and can comprehensively recover useful metals such as gold, silver, and iron. In addition, several metal compounds such as gold, silver, nickel, aluminum, cobalt, antimony, palladium, bismuth, tin, etc. are easy to reduce and easily generate volatile chlorides, and are also suitable for treatment by segregation. r >< (,, r >Sand making production line

The disadvantages of the separation method are higher costs, larger infrastructure investment, and higher production costs. It is estimated that the infrastructure investment of the separation method is about that of a flotation plant with the same capacity. Twice, the production cost will be ~ times higher. Therefore, when using the segregation method to process difficult-to-separate copper oxide ores, it is believed that the copper grade in the raw ore should be greater than % to obtain better economic results. Therefore, the segregation method is only used to solve Those ores that cannot be processed by other methods. Therefore, before using this method, a comprehensive study should be conducted on the ores to be processed. If the ores can be processed by other methods, the segregation method is not suitable.
