As Cyanex 272 is a commercialised solvent for cobalt and nickel separation, differences of cobalt and nickel's pH50 values are larger than 1.3, implying a good separation between cobalt and nickel. In contrast, difference of cobalt and manganese's pH50 values using Cyanex 272 is approx. 0.3, suggesting difficulty separating cobalt …

Manganese plays a considerably important role in the steelmaking industry, which is often used as desulfurizer, deoxidizer, or alloy additive. ... Sodium salts were used in the reduction roasting and magnetic separation process to separate and recover iron and manganese from the high-iron manganese oxide ores to utilize the complex ores.
Iron and manganese removal efficiencies of 90-99 percent can be achieved reliably. There are many factors that go into determining the type of iron and manganese problem your customer has, but the good thing is that there are ways to prevent them from happening and there are ways to treat them once the problem occurs. Solving the …

The formation of ferromagnetic MnxFe3−xO4 with strong magnetism resulted in an inferior separation of manganese and iron by magnetization roasting-magnetic separation process. With the increase ...
Several treatment methods may be used to remove iron and manganese from drinking water supplies. This chapter provides an overview of treat- ... and increased cost for media disposal. In most cases, separate treatment for radiological contaminants may result in a lower life-cycle cost. EXCERPT. 38 Iron and Manganese Removal Handbook
