Nonioic polyacrylamide of N100 can be replaced by Chinafloc N0009
N100 and N300 are two kinds of nonionic flocculant with 0 hydrolysis degree and medium molecular weight and medium viscosity ,mainly used for mineral processing .Chinafloc N0009 and Chinafloc N0010 can replace of them totally with good result.
Beneficiation requires the use of a large amount of water, through the mineral washing and flotation will be useful minerals and useless minerals for separation, useful minerals dissolved in acid and base to form hydroxide or salts, and undissolved substances through flocculation separation, polyacrylamide in mineral processing is the main role of water and gangue separation, so that the recycling of water, In addition, polyacrylamide can dehydrate the gangue settling and separating sludge.
Many minerals use this flotation and washing process, such as coal, iron ore, phosphate, aluminum, copper, gold, zinc ore, sand washing and so on. These mines usually use anionic polyacrylamide and non-ionic polyacrylamide. Non - ionic is suitable for acidic and high salt solution use.
The following examples illustrate the application of polyacrylamide in mineral processing:
1, aluminum ore in suspension, clarification, wastewater treatment, concentration and sedimentation filtration need to choose polyacrylamide.
2, calcium carbonate need to choose polyacrylamide when concentrated.
3, copper ore, nickel ore, zinc ore, titanium dioxide in the acid after the clarification need to choose polyacrylamide.
4, phosphate in wastewater treatment also need to choose polyacrylamide.
5, sand washing, washing glaze, coal washing need to choose polyacrylamide when settling and filtering.
In addition to the above examples, there are many examples of the use of polyacrylamide beneficiation, and it is not limited to the use of anionic and non-ionic processing, such as gold, in the acid solution clarification needs to choose cationic polyacrylamide, some coal mines contain more clay substances when washing coal, The suspended particles in water may choose weak Yin (that is, about 10 degrees of hydrolysis) polyacrylamide.
