2. Eco-Friendly Gold Leaching Agent Instruction of Usage
(1)Jinzhong brand eco-friendly gold leaching agent executive standard
Q/LYHD-001-2015
(2)Suitable production technology
It is suitable for particulate oxidized gold and silver ores, enable such production technology: heap-leaching, pool-leaching,mixing,carbon slurry, and mine holes cleaning.
(3) Product forms
It appears in solid bulk or powder, easy to dissolve in water, and can be used after dissolution by water.
Main ingredients: sodium oxide,iron carbide, nitrogen, ammonium, calcium and etc.
(4)Adjust PH value
During production, first adjust the PH value of backwater to 11±1 by using the caustic soda or quicklime, and then add the Jinzhong brand potion.
(5)Usage concentration
Base on the actual ingredients of ores, and achieve the optimum result by implement experiment to obtain the ideal concentration of potion.
(6)Method of usage
Jinzhong brand is similar to sodium cyanide method during the actual producing process. The barren solution can reuse and compatible with cyanidation. Add the Jinzhong brand potion into the barren solution pool, rinse by backwater continuously to dissolve.If there is any black slag occurs, won't affect further use.
(7) Cautions
| a) Recommend to use golden coconut shell as complement extraction potion to absorb carbon or zinc powder. |
| b) Recommend to test content level,PH value of the pregnant solution,and concentration of gold-leaching agent. |
| c) The strong oxidant such as hydrogen peroxide,potassium permanganate is not recommended to put together with gold leaching agent(can do some pretreatments). |
| d) It (Jinzhongpai) is not repelled with assistant potion: ammonium hydroxide, sodium sulfide, potassium ferricyanide, lead nitrate, sodium hypochlorite during complex ores pretreatment. |
| e) Jinzhong brand is not repelled with sodium cyanide if use both at the same time. |
| f) The' oxygen-rich leaching process 'of all-slime cyanidation CIP technology has negative influence on the gold extraction agent(Jinping brand). |
