The fast precipitation agent of iron ore wastewater can adapt to the clear water quality of raw ore wastewater.In different grade of iron ore cleaner tailings in the sewage treatment has obvious advantages and economic advantages, the quality of the iron powder selection is solved clean. Concentrate contains a large number of gangue, resulting in the concentrate grade can not meet the requirements, QUANSEN polyacrylamide flocculant can improve the grade of concentrate to meet the requirements, reduce tailings run and and the process of the consumption of large quantities of drugs, thereby reducing the enterprise's large demand for products and unnecessary costs.
Application of QUANSEN PAM in iron mine
Iron mine water treatment flocculating agent, water treatment with iron ore price and molecular weight polyacrylamide big doesn't mean performance good, small molecular weight does not mean performance is poor, mainly depends on use, if used for desliming in sewage treatment field, also have to combine desliming equipment and the characteristics of the sludge, if it is used in conventional crawler type filter press, high molecular weight may lead to blockages in filter cloth and take off the water is poor, affect the dehydration effect. If it is used in centrifugal desilting machine, the requirement of molecular weight should be higher due to different operating principles, and the flocculation should be as strong as possible. It can also be understood that flocculation should be strong enough, so products with higher molecular weight should be selected.
【mechanism of QUANSEN PAM】
● Adsorption bridging
PAM molecular chains are fixed on the surface of different particles, and the Bridges of polymers are formed between the particles, which cause the particles to form aggregates and settle.
● The surface adsorption
Adsorption of polar group particles on PAM molecules.
● Enhanced role
PAM molecular chain and dispersed phase, through various mechanical, physical, chemical effects, the dispersed phase will be linked together, forming a network.Polymer polyacrylamide has high viscosity and is one of the most widely used water-soluble polymer compounds.
【selection of QUANSEN PAM】
Iron ore wastewater treatment anionic polyacrylamide not only should consider its actual molecular weight, price, etc., degree of hydrolysis is one of the indicators must be considered, because it is very important to use effect, generally speaking, the less the greater the degree of hydrolysis, adsorption, adverse to the adsorption and hydrolysis of spending small, dissolving ability is poor, not enough to make molecular chain extension, bridging, experiments show that the hydrolysis of polyacrylamide degrees at around 30%, flocculating ability strongest.

【QUANSEN PAM Product performance】
1. The unique flocculation sedimentation effect can be achieved by using this product in a small amount.
2. This product and tailings water reflection time is short, reflecting speed is fast.The knot is compact.
3. This product can be used for tailing sedimentation, tail slag sedimentation, tail slag centrifugal separation and so on.
The dissolving concentration is 0.2-0.4 %. Non-iron containers should be used.Use 60 ℃ below the water, will flocculant while stirring evenly and slowly into the water, make the flocculant with water in the container fully mixing, continuous mixing time can be used after 60 minutes, when the water temperature is too low to extend the time of mixing, mixing blade linear velocity depending on the container.
Dilute the dissolved tailings water with pure water, use the concentration between 0.05 and 0.1%, use the valve or metering pump to control the flow rate and evenly add to the tailings water (also can directly prepare the solution with concentration between 0.02 and 0.1%).
1. If the solution is not properly handled, the more insoluble floc will be suspended on the water surface, which should be filtered or slowly wait for dissolution before use, without affecting the use effect.
2. The added amount should be moderate, and too much or too little can't achieve obvious flocculation effect. Users should adjust the amount according to different conditions such as the quality of tailings water, water flow speed and solid content.
3. If the amount of flocculant is low, the effect is not ideal, but the increase of the amount of flocculant will lead to the occurrence of problem such as drawing. The method of reducing or increasing the concentration of flocculant solution and increasing the flow rate can be adopted to increase the amount of flocculant.Or the addition of flocculant to move back, so that flocculant and tailings water mixing time longer can also resolve the above problem.
