The photoresponses of the Copper and Cobalt electrodes come from Cu 2O and Co 3O 4 respectively,while those of the Copper-Cobalt alloys electrodes result from the joint contribution of Cu 2.

Studying on some plant cobalt aqueous phase,it carried out high-purity cobalt oxide or cobalt oxalate preparation tests in the laboratory.

Under normal temperature and pressure,a hydrometallurgical process is presented for extracting cobalt,manganese,copper and nickel from earthy cobalt by reduced leaching with SO2-ion flotation-P507 solvent extraction.
