And (3) sorting non-metallic minerals such as graphite, sulfur, diamond, quartz, mica and feldspar, silicate minerals, non-metallic salt minerals such as fluorite, apatite and barite, and soluble salt minerals such as sylvite and halite. Another important use of flotation is to reduce ash in fine coal and to remove fine pyrite from coal. There are billions of tons of minerals and materials that are flotated worldwide each year. Large ore dressing plants process up to one hundred thousand tons of ore per day. The production index and equipment efficiency of flotation are both high, the recovery rate of the sorted sulfide ore is over 90 percent, and the concentrate grade can approach the theoretical grade of pure minerals. The flotation method is suitable for processing fine grains and fine grain materials, the fine ore particles with the particle size smaller than 10 mu m are difficult to recover by other mineral processing methods, the flotation method can also be used for processing the fine grains by using a flotation technology specially used for processing extremely fine grains, the lower limit of the recoverable particle size is lower, and the superfine flotation and ion flotation technology can recover various substances from colloid particles to molecular and ionic states. The flotation can also select the fire metallurgy intermediate products, volatile matters and useful components in slag, treat wet metallurgy leaching slag and displaced precipitation products, and recover chemical products (such as paper pulp, surface active substances and the like) and inorganic matters and organic matters in wastewater.
