(I) Ion flotation of copper smelting wastewater When ionic yellow flotation is used for ion flotation, the amount of yellow medicinal is equivalent to Cu 2+ and Pb 2+ , and the equivalent ratio of Cd 2+ is 1.5 to 2.0. Treatment water having a Cd 2+ ≤ 0.05 mg · liter -1 can be obtained. They can be selectively separated by adsorption flotation. The adsorption flotation process is shown in Figure 19. As can be seen from the figure, the first stage is carried out by using Fe(OH) 3 as an adsorption carrier, sodium oleate as a collector, and pH of 6.0 to 8.0. Floated 144 Ce, 106 Ru, y5 Zr ; second stage adsorption carrier is calcium phosphate, sodium naphthenate as collector, float 90 Sr at a pH of 10.5 to 11.0 under the conditions; the third stage is iron-cobalt cyanide as ethylene adsorption carrier, octadecyl amine acetate as collector, float 37 Cs 7.0 to 9.0 in pH conditions. Do you need a high capacity concrete batch plant or require a ready mix plant that will produce higher quality concrete repeatedly to meet precise mix designs? Shine machinery designs and manufactures customized concrete batching plants, also called wet concrete batch plants, that meet any capacity and requirement, whether you're planning to retrofit existing facilities or start from the ground up. Shine machinery designs and produces high technology concrete batch plants(mobile and stationery, wet and dry), our ready concrete mix plants are intended for both domestic and international concrete producers and contractors. From the design and specifications stages to the manufacturing, installation and commissioning of the ready mix plant, the Shine machinery experts will guide you through the process until your Concrete Plant is up and running. The new type of No Foundation Concrete Batching Plant is a Concrete Batching Plant that can act as Mobile Concrete Batching Plant when it is trailed by tow truck. Besides this type of concrete Batching Plant can also work in one site to produce concrete to meet the customer's need. 40 No Foundation Concrete Batching Plant 40 No Foundation Concrete Batching Plant,Wet Concrete Batching Station,Wet Mobile Concrete Mix Machine,Dry Concrete Batching Plant Shandong Shenghuai Trading Co., Ltd. , https://www.shinebatchplant.com
The ion flotation method using xanthate is worried that the residual xanthate in the treated water is too high, which affects the quality of the treated water. The above process can be used to treat COD in water up to 20 mg · l -1 , which meets the discharge requirements, but the treatment water is slightly yellow. When mixed with other drainage and neutralized, the final treatment water is transparent and clear.
(II) IPU flotation The so-called IPU flotation is the abbreviation of ion flotation-precipitate flotation-Uitra fine particlotation.
For example, in lead-zinc processing plant, the thickener overflow zinc concentrate containing copper, zinc, cyanide, cadmium, xanthate and a frother, flow of the process in Fig. 18 can be used.
(C) adsorbing a low concentration of radioactive waste flotation nuclear fuel reprocessing process, a low concentration of radioactive waste discharged, contain uranium fission products which have long half-life of strontium, cesium, cerium, ruthenium, zirconium five kinds. 
The removal rate of various radioactive materials is high, and the amount of slag is greatly reduced compared with the conventional flocculation precipitation method.
