The separation of nickel, copper, zinc, and cadmium by anion-exchange chrornatography has been found to be particularly suitable for the analysis of most commercial silver solders.
The ground ore is usually treated by a differential flotation process to separate the zinc-bearing particles from the waste rock, yielding a high-grade zinc concentrate and a waste product calling tailings. The cadmium content of the zinc concentrate is usually around 0.3% to 0.5%.
The separation of cadmium, zinc, and lead from aqueous solutions using inorganic solid-phase extractants has been examined. An inorganic solid-phase extractant (ISPE-302) was prepared by attachment of bis (2,4,4-trimethyl)monothiophosphonic acid on a functionalized silica surface.
(d) cadmium is usually associated with zinc minerals; and (e) the mutual separation of Zn 2+, Cd 2+, and Hg 2+ is analytically difficult because of their similar physicochemical properties.
Cadmium and zinc concentrations in kidney and liver have been measured under different exposure situations in different species including man. The results show that zinc increases almost equimolarly with cadmium in kidney after long-term low-level exposure to cadmium…
A pH‐DEPENDENT MODEL FOR THE CHEMICAL SPECIATION OF COPPER, ZINC, CADMIUM, AND LEAD IN SEAWATER Alberta Zirino. Marine Environment Division, Naval Undersea Center, San Diego, California 92132. ... Separation Science and Technology, 53, 6, (863), (2018). Crossref.
D2EHPA is a widely used metal extractant for separation of different metal ions, but the work on separation of cadmium and zinc by using D2EHPA as a mobile carrier is scanty. The present work examines the possibility of using a SLM technique to separate cadmium and zinc from dilute solutions by using TOPS-99 as an extractant.
Metalcess provides cadmium distillation furnace to recover cadmium material. The high cadmium-zinc can be treated by the distillation furnace directly to separate cadmium and zinc. Sponge cadmium is reduced and then purified by distillation furnace.
The authors studied the effect of the pH, temperature, and trilon B concentration on the reaction rate of the interaction of zinc and cadmium dithizonates with trilon B. A method was developed on the basis of these experiments for the separation of small and approximately equal quantities of zinc and cadmium.

The use n-octylaniline have been extended to zinc (II), cadmium(II) and mercury(II) which can extracted quantitatively from there aqueous acid solutions with the reagent in different organic solvents as the diluents. The proposed method permits separation of zinc(II), cadmium(II), mercury(II) and …
Cadmium is a by-product of zinc production, much rarer and used only in small amounts. Cadmium is prettier than zinc, since it is whiter, like tin or silver. A few percent hardens and strengthens copper without decreasing its conductivity greatly.
Therefore, in the present study, separation of zinc from manganese, magnesium, calcium and cadmium solutions using batch countercurrent extraction simulation followed by scrubbing and stripping was carried out to provide a suitable pregnant solution for zinc electrowinning.
The separation of cadmium and zinc from a dilute aqueous sulfate media using supported liquid membrane (SLM) technique has been studied. The microporous polypropylene film Celgard‐2400 was used as the solid support for the liquid membrane and TOPS‐99 was used as the mobile carrier.
