Separation of Iron from Cobalt or Nickel

Hydrochloric. Acid Separation. In the qualitative analysis of Group III, cobalt and nickel sulfides are separated from the other sulfides and hydroxides by treatment with 1.2 hydro- chloric acid. However, no combination of time, temperature, or strength of hydrochloric acid could be found which dissolved all of the iron and none.

Iron and sulfur reaction- Learn Chemistry

This demonstration or class experiment shows the exothermic reaction of two elements, iron and sulfur, to form the compound, iron sulfide. The two solids are mixed and heated in a test-tube (or ignition tube). The reaction can be used to illustrate elements, mixtures and compounds.

Magnetic separation - Wikipedia

Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or.

Abstract. Since sodium dithionite (Na2S2O4) is often contaminated with zinc (Zn) and can form metal sulfide precipitates, it is not suitable for solubilizing iron (Fe) oxides in fractionation schemes for soil microelements. The objective was to find an alternate method to solubilize crystalline Fe oxides that would fit into a.
