The Kaolin General White Compact Block Kaolin Group Minerals as

Kaolin flotation techniques. The kaolin general white compact block kaolin group minerals as the main ingredient. Mixed with feldspar, quartz, there is a rough feeling. Also often due to the inclusion of impurities such as iron sulfide, iron hydroxide, and reduce product quality. With the exploitation of low-grade deposits, its process include: broken → grinding → classification → bleach → concentration → drying → flotation (magnetic separation). The kaolin may as ceramic, refractory bricks, art printing paper, coated paper, synthetic rubber, wire and other raw materials.

The kaolin deposits associated with a lot of mineral impurities, including iron status and the number of outstanding problems of kaolin deposits in the mining and use of. Even at veryAAC Block Machinery low iron content, but also may not meet the requirements, in general, can be used a flotation removal, but containing amorphous or near amorphous particulate ferric hydroxide, are difficult to remove.

Kaolin flotation can be dodecylamine, triethanolamine, pyridine and the like for collecting agent, and for adjusting agent Sodium lignosulphonate or calcium. PH of the medium in acidicLime Kiln medium (pH value of less than 3), kaolin grade up to 80% recovery rate of 60% to 68%.

Can be applied to ultra-fine particles flotation to sorting difficult to froth flotation processing fine particles less than 44 microns the carrier mineral, the floating particles attached to the ball millcarrier mineral separation with the foam products . Carrier available calcite, barite, sulfur mineral. Superfine flotation specialized pharmacy, general and removal of ore impurities in the same flotation reagent and sodium silicate as dispersant to improve the separation efficiency.
