Description
Technical field
The invention belongs to the precious metals metallurgy field, be specifically related to a kind of beneficiation reagent and using method that reclaims noble metal of from copper anode mud, separating.
Background technology
Copper anode mud is the byproduct of copper electrolyzing refining, is the important source material that reclaims noble metal, and in copper electrolytic process, its current potential calibration of gold, silver and platinum group metal is not carried out electrochemical dissolution and come off in cell bottom from anode with superfine particle on copper anode; The elements such as sulphur, selenium, tellurium exist with stable compound form on anode, do not carry out electrochemical reaction to sink to cell bottom; Insoluble nickel is sunken to cell bottom with the compound state.From the earth of positive pole, reclaim both at home and abroad the representative technique of noble metal such as gold and silver and mainly contain three major types: the one, full wet processing flow process is " selenium is leached in the earth of positive pole-pressure leaching copper, tellurium-chlorination, gold-alkali soaks minute lead-ammonia and soaks minute silver-gold and silver electrolysis "; The 2nd, take wet method as main, (partly) wet processing flow process that pyrogenic process, wet method combine, by domestic most producer is adopted, the trunk flow process is " earth of positive pole-sulfating roasting is steamed selenium-diluted acid and divided copper-chlorination parting-Ya sodium to divide silver-gold and silver electrolysis "; The 3rd, take pyrogenic process as main, the firing method process that wet method-pyrogenic process combines, the trunk flow process is " earth of positive pole-pressure leaching copper, tellurium-pyrometallurgical smelting, blowing-Yin electrolysis-silver anode slime are processed gold ", its capital equipment is Kaldo Furnace and pressure leaching still.In existing technique, the following shortcoming of ubiquity: noble metal spread loss in each operation is very serious; The direct recovery rate of noble metal is low; Complex procedures, returning charge is many; The tailing gold content is high, and the impurity content such as copper tellurium bismuth is many in the noble metal products, and it is residual serious that plumbous arsenic etc. are poisoned element; Automation degree of equipment is low, and energy consumption is large.Adopt floatation process to process copper anode mud, can improve widely the disposal ability of copper anode mud, for smelting has been created advantage, has been reduced flux consumption, and that domestic employing the method removes to process copper anode mud is also few, relevant experimental study is also insufficient, particularly immature to the research of the beneficiation reagent that is used for the earth of positive pole and beneficiation method, cause results of ore dressing and refining undesirable, the mine tailing bullion content is high.
Summary of the invention
Problem for noble metal separation and recovery technology existence in the existing copper earth of positive pole, the invention provides a kind of beneficiation reagent and using method that reclaims noble metal of from copper anode mud, separating, purpose is by efficient beneficiation reagent of the present invention, particularly earth of positive pole collecting agent is efficiently isolated noble metal in conjunction with suitable dressing and smelting process method again from the earth of positive pole.
A kind of beneficiation reagent that reclaims noble metal that from copper anode mud, separates, according to weight proportion, formed by collecting agent 1 ~ 10 weight portion, inhibitor 1 ~ 10 weight portion and foaming agent 1 ~ 10 weight portion, wherein said collecting agent is pine camphor xanthate and pine camphor black powder, the mol ratio of pine camphor xanthate and pine camphor black powder is 1:(0.01 ~ 25), inhibitor is calgon, and foaming agent is terpenic oil.
