Slime flotation is a kind of slime separation technology, which utilizes the difference of physical and chemical properties between coal and the refuse surface and enlarges the difference of surface wettability between coal and the refuse by adding specific flotation reagents. It selectively enriches low-lime coal at the solid-liquid-gas three-phase interface, thus realizes the separation of coal and the refuse.

Flotation reagents can improve the three-phase properties of gas, liquid and solid in the flotation system, so that the size, quantity, life and flotation speed of bubbles produced can meet the requirements. They can also adjust the surface properties of minerals, the role of minerals and other substances, and the properties of pulp, so that the minerals that can not be floated can be flotation better. The selectivity and recovery of flotation are very high.

At present, the quality of flotation reagents used in our country is uneven, mostly petrochemical wastes, the price is about RMB7000 /ton; the flotation concentrate yield is low, the consumption of reagents is large, the safety is low, the performance-price ratio is low, and the economic benefit of flotation is not significant; the irritating odor of reagents is large, the environment is not friendly, and the health of workers is affected; the appearance of the reagents is black, sticky and impurities. Many, easy to clog the pharmaceutical pipeline, often resulting in the production responsibility accident of coal flotation, resulting in a large number of resources and economic losses. International well-known brands such as Nalco, Germany,Ekof, their products are safe, environmentally friendly, energy-saving and efficient, and the price is RMB30,000 /ton. Because of their high price, the cost performance ratio is not high, so they have not been well promoted and applied in China.

Our company has been devoted to the research and development, production and sales of flotation additives for coal preparation for more than ten years since its establishment. We have established cooperative relations with domestic universities and scientific research institutes. Our products are energy-saving, efficient, safe and environment friendly. The consumption of our products is about the same as that of famous international brands Nalco and Ekof in the United States, but the price is half of it. The cost performance is superior to that of international famous brands. It is a renewal product of traditional flotation reagents. Compared with traditional flotation reagents, it has the following advantages:

1. Safety and environmental protection, conducive to safe production and the health of operators;

2. Good selectivity and adaptability to fine mud and high ash complex coal.

3. Bubble stabilization, increasing depth adjustment range, improving flotation fluidity and reducing tailings treatment cost;

4. It can reduce the surface tension of air bubbles, maintain the stability of air bubbles and reduce the power consumption of aeration stirring.

5. Energy-saving and high-efficiency, the dosage is about half of the general medicines, the recovery rate of clean coal is significantly improved, and the economic benefit is remarkable!

Now our company's products have developed in the direction of energy-saving, high efficiency, safety and environmental protection. In the future, we will increase our scientific research strength, develop more energy-saving, high efficiency, safety and environmental protection products according to different coal qualities, and maximize the benefits of enterprises on the premise of ensuring the high efficiency of pharmaceuticals, environmental protection and pollution-free.
