Beijing Hengju - Flocculants and Coagulants for Mineral Processing Industries

Beijing Hengju manufactures and supplies specialty water treatment chemicals for oilfield, wastewater treatment, potable water, mineral processing, sugar and paper industries. The HENGFLOC range of anionic, cationic and non-ionic flocculants and coagulants are produced in both Beijing, our company's headquarters and in Shanghai with a total powder polymer capacity of over 50,000t/year.

Founded 15 years ago the company has grown rapidly as a result of its involvement in the Chinese oilfield industry where a variety of our products are currently used to improve the efficiency of oil production.

In addition to complete range of powder grade polyacrylamides, marketed under the HENGFLOC trade name, our company also supplies polydadmac, polyamine and dicyandiamide type liquid coagulants to cater for all requirements of the industries that we serve.

Crystal acrylamide production from microbiological technology

We produce all of our acrylamide requirements utilising microbiological technology to produce high quality crystal acrylamide, which enables our range of ultra high molecular weight polymers to be produced. As a result of these investments in new technology our products are capable of competing with other global suppliers and are now being exported around the globe.

HENGFLOC flocculants and coagulants for mineral processing industries

The extensive range of HENGFLOC flocculants and coagulants includes anionic, non-ionic and cationic charged polymers, all produced at varying molecular weights, so that all applications in the mineral processing industry are catered for.

Applications for our products are found in many industries including:

• Coal
• Copper
• Alumina
• Gold / silver
• Lead / zinc
• Nickel
• Uranium
• Iron / steel
• Titanium dioxide
• Potash
• Phosphoric acid
• Sand / gravel

HENGFLOC flocculants - a complete range

In most mineral processes where there is a flocculant requirement for either a sedimentation or centrifugation application then a high or ultra high molecular weight product is desired. The HENGFLOC product range offers ultra high molecular weight products, ensuring maximum performance and cost efficiency for sedimentation and centrifugation applications.

Our range of medium molecular weight HENGFLOC polymers are particular effective on sedimentation applications where reasonably high settlement rates are required although not at the expenses of poor overflow clarities. These products are also often the most effective choice when underflow densities from the clarifiers/thickeners need to be well controlled.

Our lower molecular weight HENGFLOC polymers are used as filtration reagents on applications such as membrane filter, vacuum filter or belt press applications. By using such low molecular weight flocculants the flocculated structure is strong enough to withstand the high-pressure conditions but also develops a permeable structure allowing rapid water release.

HENGFLOC coagulants

Our range of HENGFLOC polydadmac and polyamine coagulants are often used in conjunction with our flocculant range where high clay content substrates (or very finely suspended solids) require solid/liquid separation. The overall effect is very high quality supernatants with improved rates of solid/liquid separation.
