Aiseolas Teachtaireacht
Ore treatment plant, also called dressing plant or concentrating mill, is heavy water consumer. The reason is the mineral processing process need huge volume water, which is used in the washing process and flotation process to separate valuable mineral and useless mineral. Valuable mineral will form hydroxide or salt in acid or alkali. The undissolved matter will be separated by flocculation. The tailing wastewater of mineral processing contain multiple harmful substance, namely heavy metal ion and mining chemical. Heavy mental ion includes copper, zinc, lead, nickel, barium, cadmium and rare element. In some special cases, there will be arsenic or mercuric phenate. Mining chemical includes cyanide, xanthate, black catching agent and pine oil. If the wastewater of mineral processing is not treated well, it will be great harmful or hazardous. 
Mining Polyacrylamide has the role of precipitating agent and stabilizer. In the treatment of tailing, polyacrylamide separates the water and gangue mineral. It acts as precipitating agent and bridge the organic colloidal particle and water-soluble substance. After the bridging, the sedimentation efficiency is greatly increased. With the help of mining polyacrylamide, the separation speed of solid and liquid  in the tailing wastewater is increased. In the same  time, the recovery rate and yield of mineral are also increased. 
In the mineral process, polyacrylamide acts as stabilizer to prevent the sediment and coherence of rock particle, which help keep the stability and mobility of ore pulp. The mining efficiency and mineral recovery rate are both increased. Many mineral industries need polyacrylamide in the mineral process, including: coal, gold, silver, copper, iron, lead, zinc, aluminum, uranium, nickel, phosphorus, potassium,  manganese, salt, tungsten and a bunch of rare metals. For different mineral industry, the mining polyacrylamide used is different. There are two main types polyacrylamide used: anionic polyacrylamide and nonionic polyacrylamide. For minerals that use washing and flotation process, like coal ore, iron ore, phosphate, aluminum ore, copper ore, gold ore, zinc ore, sand washing, anionic polyacrylamide and nonionic polyacrylamide are used normally. Nonionic polyacrylamide are mostly used in the acid or high salinity solution.
Below are application samples of polyacrylamide in mineral process:
1. Aluminum ore: the suspension, clarification, waste water treatment, concentration, sediment and filtration process all need polyacrylamide
2. Calcium carbonate: the concentration process need polyacrylamide
3. Copper ore, nickel ore, zinc ore and titanium dioxide: after dissolve in acid, the clarification need polyacrylamide
4. Phosphate: the waste water treatment need polyacrylamide
5. Sand washing and coal washing: the sediment and filtration process need polyacrylamide
6.  Gold ore: after dissolve in acid, the clarification need cationic polyacrylamide
7. Coal with too much clay: the suspension particle  is tiny. Weak anionic (low hydrolysis degree, around 10) polyacrylamide is used.
To find the most suitable polyacrylamide for ore treatment plant, lab test is needed first. After lab test, pilot test is needed on machine in the plant to check performance in the real situation. After test, the polyacrylamide type will be finally confirmed.

What types of mining operations commonly use polyacrylamide?
Mining Polyacrylamide, a versatile polymer, finds widespread application in various types of mining operations due to its unique properties and benefits. Its usage is particularly prevalent in the treatment of tailings, where it serves crucial roles as a precipitating agent and stabilizer.
1. Gold and Silver Mining:Polyacrylamide is commonly employed in gold and silver mining operations. In these settings, it aids in the separation and removal of impurities from ore pulp, enhancing the efficiency of sedimentation processes. The improved sedimentation efficiency contributes to increased mineral recovery rates.
2. Coal Mining:In coal mining, polyacrylamide is utilized to address challenges associated with tailings management. It acts as a flocculant, promoting the aggregation of fine particles, and facilitates their settlement. This aids in the dewatering of coal tailings and reduces the environmental impact of waste disposal.
3. Copper and Other Metal Mining:Mining operations involving copper and various other metals benefit from the use of polyacrylamide. It serves as a stabilizer, preventing the sedimentation and coherence of rock particles in the ore pulp. This stabilization enhances the fluidity of the pulp, making it easier to handle and process.
4. Iron Ore Mining:Polyacrylamide plays a role in iron ore mining by improving the sedimentation of particles during the tailings treatment. The bridging effect of polyacrylamide helps in the formation of larger aggregates, leading to more efficient settling and separation of solids from liquid components.
5. Phosphate Mining:Phosphate mining operations utilize Mining Polyacrylamide to enhance the efficiency of sedimentation processes. By acting as a precipitating agent, polyacrylamide aids in the removal of suspended particles and organic matter from tailings, contributing to clearer water discharge.
6. Uranium Mining:Polyacrylamide is applied in uranium mining for its role in sedimentation and tailings treatment. It helps improve the clarity of liquid components, facilitating the extraction and recovery of uranium while minimizing environmental impacts.

How does polyacrylamide contribute to increased sedimentation efficiency in tailings treatment?
Mining Polyacrylamide plays a pivotal role in enhancing sedimentation efficiency during tailings treatment in mining operations. Its unique chemical properties make it an effective precipitating agent, facilitating the separation and removal of suspended particles from the liquid phase. 
1. Flocculation and Bridging:Polyacrylamide is known for its ability to induce flocculation, a process where fine particles aggregate to form larger clusters. In tailings treatment, polyacrylamide molecules create bridges between individual particles, bringing them together into larger, denser flocs.
2. Increased Particle Size and Weight:The bridging effect of polyacrylamide results in the formation of larger and heavier aggregates. As a consequence, the settling velocity of these aggregates during sedimentation is significantly increased. Larger and heavier flocs settle more rapidly, promoting the separation of solids from the liquid component.
3. Enhanced Clarification:The introduction of Mining Polyacrylamide leads to the formation of well-settled flocs, which improves the clarity of the liquid phase in the tailings. This enhanced clarification allows for more efficient separation of water from solid particles, reducing the turbidity of the discharged water.
4. Reduction in Turbidity and Suspended Solids:Polyacrylamide aids in reducing turbidity by promoting the settling of suspended solids. The bridging mechanism ensures that even fine particles, which might otherwise remain in suspension, are effectively brought together and settled, leading to clearer water.
5. Improved Dewatering:By promoting the formation of larger and denser flocs, polyacrylamide contributes to improved dewatering of the tailings. This is particularly crucial in reducing the moisture content of the solid residues, making them easier to handle and transport.
