A high molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable.
US4617359A - High molecular weight polyacrylamide
This invention discloses a process for the polymerization of acrylamide and for the copolymerization of acrylamide with other monomers. It employs a ferrous/hydroperoxide redox initiator system that greatly enhances the molecular weight of the polymer formed. These high molecular weight acrylamide polymers offer outstanding advantages in enhanced oil recovery as injection water viscosifiers.

Isolation and Characterization of Polyacrylamide-Degrading
The degraded PAM samples were analyzed by gel-filtration chromatography, Fourier transform infrared and high-performance liquid chromatography. The results showed that high-molecular-weight PAM was partly cleaved to small molecular oligomer derivatives and part of the amide groups of PAM had been converted to carboxyl groups.
Polyacrylamide (PAM) is a synthetic, potassium based long-chain polymer. It has a high-molecular weight and is a kind of water-soluble polymer, that is produced through polymerization of acrylamide. The global polyacrylamide market will grow at an impressive rate owing to its increasing use mainly in petroleum and wastewater sector.

cosmetics (Yan 1998). For the same applications, high molecular weight polyacrylamide (PAM) has been widely used because of its effectiveness and low price, but it is nonionic. If a polymer has charged groups on its chain, it will be more effective as a retention aid in papermaking and as a flocculant. Hence, many cationic polymers are prepared by
- How much energy does a wastewater treatment plant use?
- The acquired data showed that the specific energy consumption at the investigated WTP (depending on the period and location) was between 1.561 and 2.580 kWh/m 3 treated wastewater, the annual averages being between 1.786 and 2.334 kWh/m 3 (depending on WTP).
- Does Russia have a good sewage treatment plant?
- In Russia, the amount of pollution per capita is several times less than in other countries and this fact determines the quality of waste water, which comes at the sewage treatment plant (table 2) [1–3]. The pollutants ratio needed for normal biological treatment is far from required.
- What factors influence the energy consumption for wastewater treatment?
- Many factors influence the energy consumption for wastewater treatment. The energy demand depends on the plant location, plant size, type of a treatment process and aeration system employed, effluent quality requirements, age of a plant, and knowledge and skills of the operators.
- Can biogas be used in a wastewater treatment plant?
- The US Environmental Protection Agency (USEPA) 8 noted that 25–50% of a WWTP’s energy needs could be met by biogas, even with conventional methods involving aerobic treatment. In fact, wastewater contains approximately five times more embedded energy than is required for its treatment 9.
