METAL, PRECIOUS METAL RECOVERY FROM EFFLUENT
It is very worthy to recover precious metal like Gold, Cobalt, Copper, Nickel, Zinc, Platinum, Palladium, Cadmium, Scandium, Gallium, Rhenium, Molybdenum and essential to remove Mercury, Arsenic, Fluoride, Iron, Boron Radium, Phosphorus , Perchlorate, Nitrate and Lead from effluent
Heavy Metal Recovery from Effluent: A Solution to Mining and Electroplating Industries. Effluents from mining and electroplating industries contain various heavy metals, such as chromium, nickel, gold, copper, cobalt, and zinc, etc. which are considered valuable resources. However, these heavy metals are often present in low concentrations in effluent and are difficult to extract using conventional methods. As a result, the industry has become highly interested in the recovery of these metals from wastewater.
The metal recovery from effluent is not only beneficial to the environment but also has economic benefits. The use of chelating resins has shown great potential for the recovery of heavy metals from effluent. Chelating resins are synthetic polymers that contain ligands that have a high affinity for heavy metals. These resins can be used to selectively extract and recover heavy metals from effluent. METAL RECOVERY FROM EFFLUENT
Chelating Resin Process
The chelating resin process involves passing the effluent through a resin column containing the chelating resin. The heavy metals in the effluent bind to the ligands on the resin, forming a complex that can be easily separated from the effluent. The resin can then be regenerated by passing a solution of a strong acid through the column, releasing the heavy metals from the resin. The recovered heavy metals can then be further processed for reuse.
Advantages over conventional methods
The use of chelating resins for heavy metal recovery has several advantages over conventional methods.
First, the process is selective, allowing for the recovery of specific heavy metals.
Second, the resin can be reused multiple times, reducing waste and lowering costs.
Third, the process is environmentally friendly, reducing the discharge of heavy metals into the environment.
