| titleOfInvention | A kind of hot-press oxidization pretreatment method of the gold concentrate containing arsenic |
| abstract | The invention discloses a kind of hot-press oxidization pretreatment methods of gold concentrate containing arsenic, include the following steps：(1) arsenic gold concentrate will be contained, acidification ore pulp is made；(2) CuSO is added in above-mentioned acidification ore pulp 4 Hot pressing pre-oxidation is carried out afterwards, obtains oxidation ore pulp；(3) above-mentioned oxidation ore pulp is subjected to dense washing, obtains underflow oxidizing slag and overflow acid solution；(4) above-mentioned underflow oxidizing slag is subjected to alkali tune cyaniding；(5) the above-mentioned overflow acid solution in part is subjected to heavy iron with goethite process and removes part of sulfuric acid root；(6) step (5) resulting material is carried out dense obtaining underflow and overflowing liquid；(7) acidification will be participated in above-mentioned overflowing liquid return to step (1)；(8) the crystal seed return to step (5) in the underflow of gained in part steps (6) is subjected to goethite process, in step (6) after remaining underflow washing heap to Tailings Dam；(9) the underflow oxidizing slag of step (3) is subjected to Cyanide Leaching. |
