In the case of flotation coarse granules, due to the large weight, the ore detachment force is increased, it is necessary to:
1 use a sufficient amount of the most effective collector ;
2 increase the aeration of the slurry, causing larger bubbles and increasing the amount of microbubbles precipitated in the water;
3 The mixing strength of the pulp should be appropriate;
4 to increase the concentration of pulp properly;
5 Scraper should be quick and smooth when scraping.
In the case of flotation of very fine particles (usually referred to as less than 5-10 μm of slime), you need to:
1 Because the quality of the slime is very small, it is easy to adhere to the surface of the coarse particles, so that the floatability of the coarse particles is lowered, and the selectivity is deteriorated;
2 Because the slime is larger than the surface, they will adsorb a large amount of flotation agent in the pulp, which will reduce the concentration of the agent in the slurry, destroy the normal flotation process and reduce the flotation index;
3 Because the slime has a very fine surface area, the surface activity is increased, it is easy to work with various chemicals, it is difficult to sort, and it has strong hydration, so that the foam is excessively stable, and the selection may cause difficulty. Reduce the quality of the concentrate and reduce the fluidity and concentration efficiency of the foam product.
Sodium Lauryl Ether Sulfate (SLES),white or yellowish paste, an anionic Detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.). SLES is an inexpensive and very effective foaming agent.SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. They behave similarly to soap. It is derived from palm kernel oil or coconut oil.
Its chemical formula is CH3(CH2)11(OCH2CH2)nOSO3Na. Sometimes the number represented by n is specified in the name, for example laureth-2 sulfate. The product is heterogeneous in the number of ethoxyl groups, where n is the mean. Laureth-3 sulfate is common in commercial products.
SLES is prepared by ethoxylation of dodecyl alcohol, which is produced industrially from palm kernel oil or coconut oil. The resulting ethoxylate is converted to a half ester of sulfuric ACID, which is neutralized by conversion to the sodium salt.[1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. SLS and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.
SLES is a kind of anionic surfactant with excellent performance.
It has good cleaning, emulsifying, wetting, densifying and foaming performance,with good solvency, wide compatibility, strong resistance to hard water, high biodegradation, and low irritation to skin and eye.
1.SLES(Sodium Laureth Sulphate) widely used in liquid detergent.; e.g. Shampoo, dishwashing detergent, bubble bath liquid, hand washing etc.
2.If using SLES(Sodium Lauryl Ether Sulfate) to replace LABSA partially, phosphate can be saved or reduced, and general dosage of active matter may be reduced, in washing powder and detergent for heavy dirty.
3.SLES(Sodium Lauryl Ether Sulphate) can be used as lubricant, dyeing agent, cleanser, foaming agent and degreasing agent.; e.g. printing and dyeing industry, petroleum and leather industry.
