Flotation Introduction
May 21, 2018

Graphite, sulfur, diamond, quartz, mica, feldspar and other non-metallic minerals and silicate minerals and non-metallic salt minerals such as fluorite, apatite, barite, and soluble salt minerals such as potassium salt and rock salt do not. 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 and fine-grained materials. The use of other beneficiation methods makes it difficult to recover finer ore particles smaller than 10 μm. It can also be handled by flotation. Some flotation technologies that deal with very fine particles have lower recoverable particle size limits. Ultrafine flotation and ion flotation technology can recover everything from colloidal particles to molecules and ions. Flotation can also be selected from pyrometallurgical intermediates, useful constituents in volatiles and slag, hydrometallurgical leachable slag and displaced precipitated products, recovery of chemical products (such as pulp, surface active substances, etc.) and wastewater Inorganic and organic matter.
