Method for producing nickel chloride solution with noble-metal leaching agents as raw materials

The invention discloses a method for producing a nickel chloride solution with noble-metal leaching agents as raw materials. The method includes: the noble-meta leaching agents are taken as the raw materials, and requirement on final pH value of deironing noble-metal leaching agents is 3.5-4.0; during oxidation process of the deironing agents, reaction potential is controlled to be 450-550mv, chlorine feeding time is controlled to be 4-6 hours, and the pH value of the chlorine-fed solution is adjusted to 3.5-4.0; during extraction of P507, the volume ratio of an extracting agent P507 to a thinning agent of sulfonated kerosene is 1:3, the saponification rate of sodium soap is 70%, the volume ratio of extracted organic phase to water phase is 3:1, the extraction stage is grade 7, the phase ratio:O:A=4:1, and the extraction form is counter-current extraction. The method has the advantages that nickel of the noble-metal leaching agents is recycled, the qualified nickel chloride solution is produced, requirements
