In this thesis, the use of the formation of macromolecular metal complexes, restore - precipitation reaction of metal Insoluble and volatile oxide polyvalent metal compound Insoluble series is generated to explore certain metal enrichment and separation problems encountered in the metallurgical process. The full text includes a total of five parts: First, the enrichment and separation technology in the metallurgical process development and research progress do a literature review. Synthesis of terephthalic acid copper (II) coordination polymer (Cu-BDC Figure a) and fumaric acid copper (II) coordination polymers (Cu-FMA, Figure b), and copper ion adsorption behavior of terephthalic acid and fumaric acid. Above copper (II) complexes were characterized by elemental analysis, infrared spectroscopy, atomic absorption, scanning electron microscopy and other means. The results show that the synthetic polymer complex has a fixed composition, insoluble in most organic solvents. Relative to the traditional separation technology, the process is simple separation technology, raw materials can be recycled, is a new type of green separation technology, with potential applications in the recovery of low concentrations of valuable metals, governance toxic heavy metals pollution. Synthesis of rare earth and polystyrene / 4 - (4 - bromophenyl)-4 - oxo-2 - butenoic acid macromolecules metal complexes, complex structure shown in Figure c: at the same time, also studied polystyrene / 4 - (4 - Bromophenoxy) -4 - oxo-2 - butenoic acid adsorption behavior on the part of the rare earth ions, the results show a strong adsorption effect of such ligands on the rare earth ions. Fourth, the paper uses restore - precipitation method, the addition of anti-copper agent to make it precipitated copper with a reducing agent to a price, of a similar nature metal copper, nickel can be effectively separated. Using this method for the removal of trace copper in Jinchuan Nickel anode liquid metallurgy technical problems conducted in-depth study to examine in addition to the amount of copper reaction process, the reaction temperature, reaction time, and reducing agent and in addition to copper agent and other conditions in addition to copper effect. Fifth, the use of part of the variable valence metal such as nickel, cobalt, manganese, lead and capable of changing the nature of the valence state, will be easy to obtain and inexpensive chlorine gas is bubbled into the containing these metals with calcium, magnesium mixed solution through the oxidation reaction, so that they Mg (OH generate smaller solubility insoluble compound precipitates, thus generated with coexisting calcium, magnesium separation: 2Ni (OH) 2 Cl2 2OH-= 2Ni (OH) 2Cl-reaction of OH-from alkali ) 2 precipitation reaction resulting precipitate particles lower valence state hydroxide, calcium, magnesium separation effect is remarkable, the process is simple, the separation process is expected to be applied to industrial processes nickel, cobalt, manganese, lead, calcium, magnesium .
