Flotation Use
May 21, 2018

The flotation method is widely used in the sorting of fine-grained inlaid metal minerals, non-metallic minerals, and chemical raw material minerals. The country's alleged beneficiation is the "oredressing" ore dressing from Western languages. The original meaning can be similarly translated as ore conditioning (preparatory work before smelting). Nowadays, due to the expansion of technological content, Western countries usually use "mineral processing" ( "Mineral processing". At present, popular scholars have said that the accepted flotation, to be precise, should be a mineral "froth flotation".

Another important use of flotation is to reduce the ash content in the fine-grained coal and remove fine-grained pyrite from the coal. There are billions of tons of ore and material processed by flotation every year throughout the world. Large concentrators handle up to 100,000 tons of ore per day. The production index and equipment efficiency of flotation are both high. The recovery rate of sulfide ore is more than 90%. The concentrate grade can be close to the theoretical grade of pure minerals. Flotation is used to treat polymetallic symbiotic minerals. For example, copper, lead, zinc, and pyrite can be separated from polymetallic ores such as copper, lead, and zinc, and a high sorting index can be obtained. Flotation is suitable for the treatment of fine-grained and fine-grained materials. It is difficult to recover finer ore smaller than 10 μm by other beneficiation methods and can also be treated by flotation.
