| titleOfInvention | Arsenic-bearing gold concentrate treatment technology |
| abstract | The invention relates to an arsenic-bearing gold concentrate treatment technology which comprises the following steps: 1) evenly mixing the gold concentrate according to the ore proportioning requirement; 2) airing the evenly mixed gold concentrate until the water content is no more than 8%; 3) feeding the gold concentrate powder into a roasting furnace for sulfation roasting at the roasting temperature of 630-700DEG C, and roasting for 1.5-2.5 hours; 4) delivering the roasted slag into a leaching tank, adding water to prepare ore pulp according to the condition that the ratio of liquid to solid is (1-1.5):1, then stirring and adding concentrated sulfuric acid as a leaching agent, and leaching at the leaching temperature of 90-150DEG C for 2-4 hours; 5) after leaching is over, performing solid-liquid separation, washing the leached slag, then adding base to prepare an ore pulp, delivering to a cyaniding workshop section for cyaniding and leaching, then performing solid-liquid separation again, replacing the cyanided leachate to produce gold mud, refining the gold mud to produce gold. The technology is simple, and can be used for overcoming the defects that the dearsenificaiton is halfway and secondary coating is formed and the like; the dearsenification effect is good, the leaching rate of the gold is high and up to more than 97%. |
