The invention relates to a method of recovering copper , the method comprising the steps of:
(a) biologically oxidizing copper sulfide concentrate in the form of a slurry to dissolve copper into soluble copper sulfate;
(b) subjecting the slurry to solid/liquid separation to produce a solution having a high copper concentration;
(c) treating the solution with a solvent extractant to exchange copper ions with hydrogen ions by the reagent to produce a residual liquid which is high in sulfuric acid and low in copper sulfate;
(d) eluting the solvent extractant with a sulfuric acid solution;
(e) accumulating copper from a sulfuric acid solution;
(f) using at least a portion of the raffinate from step (c) in step (a).
TDS water quality detection pen is a detection device used to analyze the total salinity of water quality. TDS in Chinese means total dissolved solids, which is defined as the total amount of various soluble mineral salts in water, including the total amount of inorganic salts and organic substances.
