Aug 21, 2020· The cyanidation plants has been using sodium cyanide to dissolve the gold from the ore in order to recover the gold from the leaching solution. The formula is as follows: 2Au+4NaCN+O2+2H2O2Na +2NaOH+H2O2. 2Au+4NaCN+H2O22Na +2NaOH. From the electrochemical reaction, it can be known that dissolving 1 gram of

2010 7 1 Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5. ppm gold with high arsenic and antimony.. The second sample had a low gold content 2.5 ppm but a high silver content 160 ppm.The first series of test work focused on the determination of conditions for extracting

Abstract. Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5 ppm gold with high arsenic and antimony. The second sample had a low

Jun 15, 2018· The results of gold recovery and cyanide consumption versus variation of time and temperature of roasting process are presented in Table 6. cyanide consumption increased for ore and its gold and arsenic grades were 10.5 4000 3650 97. Despite the difference in rate.16 min 1 for the first and second samples.65 10.
