Mercury pollution treatment Mercury pollution includes pollution of mercury-containing wastewater and mercury vapor. Gold mines now employ of amalgamation coarse gold recovery is common, mercury-containing wastewater treatment method relating to the lot, boron, sodium reduction, metal reduction, sulfide precipitation, adsorption and ion exchange method. In the production of gold mines, mercury vapor is a serious pollution. Mainly due to the amalgamation operation. Up to a concentration of 0.9mg / m3, in general in the 0.1mg / m3, it has exceeded the plant health standards (0.01mg / m3) 10 times, therefore, must take protective measures such as purification and condensation - adsorption, adsorption of potassium permanganate method. According to the survey, gold mines using amalgamation operations (such as Erdaogou Gold Mine) have not experienced mercury poisoning in recent years due to enhanced operational management and protective measures and the use of operator rotation. Robot has been used widely in modern industry. With the deeply urge for automation in polishing field, robot has been a smart mehtod to realize grinding automation. Our active contact flange connects with robot, can work in grinding polishing sanding, high working efficiency, low cost and cleaning working environment. More and more manufacturers choose this method to realize automation reform. So this method has been used in metal,plastics,acrylic, wood, compound material processing in 3c, household sanitary ware, auto parts, transportation tools etc. polishing use robot,robot use in polishing,robotic polishing machine DARU Technology (Suzhou) Co., Ltd. , https://www.yiwufizz.com
