Negative pressure type chlorination gold leaching process

The invention discloses a negative pressure type chlorination gold leaching process. The negative pressure type chlorination gold leaching process comprises the following steps that S110, a liquid reaction material is prepared, and pure water and concentrated hydrochloric acid is added into a reaction kettle for being uniformly mixed to obtain the liquid reaction material; S120, a gold-containing material is pretreated, the gold-containing material and sodium chlorate are evenly mixed according to the weight ratio of 1 to (0.5-1), and a gold-containing pretreated material is obtained; S130, the reaction kettle is preheated, and hot water is introduced into a jacket of the reaction kettle; S140, feeding and reacting are carried out; S150, chlorine is removed at negative pressure; and S160, cooling and filtering are carried out. The negative pressure type chlorination gold leaching process has the beneficial effects that compared with a traditional chlorination gold leaching method, the phenomenon of pipe explo
