Anionic polyacrylamide Rheomax DR 1050 can be replaced by Chinafloc A0109
Rheomax DR 1050 is a member of the Rheomax DR 1000 series of advanced polymers with are designed to enhance thickener performance by providing a strong aggregate structure and tolerance of flux variations,resulting in superior solids liquids seperation .
The function of polyacrylamide flocculant in water treatment is obvious to all. Anionic polyacrylamide reagent is widely used in mining, mineral processing and metallurgy and enjoys a good reputation in the industry.
Anionic polyacrylamide reagents are popular because they can be used by manufacturers to promote rapid sedimentation of effective solids or accelerate concentration of fine objects, improve solid-liquid separation, reduce tailings losses and environmental pollution, and reduce production costs. The superior efficacy of the drug gradually raised its position in the industry.
After coal is mined, it is processed and sorted to obtain the product. Flotation cleaned coal is recovered by precipitation, filtration or centrifugation. In this process, anionic polyacrylamide is used as a flocculant to facilitate solid-liquid separation, then filtered and centrifuged in a concentrator, and the anionic polyacrylamide flocculant is used again.
After crushing and sifting the gold and silver, the minerals are further ground by adding water and lime to the mill, which is then precipitated in the next concentrator. At this stage, anionic polyacrylamide is used to facilitate rapid settlement of solids and the substrate is filtered through a series of filter tanks. Anionic polyacrylamide flocculant is added to the thickener before filtration
In addition to coal beneficiation, there are iron, manganese, copper, gold, zinc, etc., these mine wastewater is generally acidic, the treatment of this kind of wastewater is generally to use neutralization method, adjust its PH value, the most commonly used limestone and lime to do adjustment agent. For example, after neutralization of iron ore wastewater, the main components of wastewater sludge are ferric hydroxide Fe(oH)3 and colloid, Ca(OH)2 calcium hydroxide and colloid, Fe(OH)2 ferrous hydroxide particles, and other ions. Cationic polyacrylamide (CPAM) can be used to dehydrate iron ore sludge. It is not difficult to find out from some common cases. In fact, there are two real applications in mineral processing
1. It is often used for dewatering concentrate, accelerating settling of frame mud, purifying backwater and improving the working efficiency of thickener.
2. Selective flocculation is adopted for the pulp of fine-grained minerals to change the surface characteristics of the target mineral particles and appropriately increase the particle size, so that flocculation and precipitation are conducive to the separation from gangue.
Whether in coal preparation or other metal ore, flocculant is undoubtedly a necessary agent, but also a relatively economical agent, the process of mineral processing is actually the process of creating value, polyacrylamide as the current mainstream flocculant
