| Abstract: | Abstract: The paper studies the pretreatment of getting rid of the arsenic by adding the sodium hydroxide in the course of gold extraction by cyanidation. Thereby the time of soaking gold is reduced and the extraction rate is enhanced. The best condition of using this gold extraction method by test is that the time of soaking gold is twenty hours and extraction rate can achieve ninety-five percent and that the value of PH is nine to ten. |
