Product Characteristics
1. Safe & Environmental friendly Zhongtai advocates “green mining ,eco-friendly gold-leaching agent”, innovative ideas. This product is environmental friendly, low toxicity, do not contain any cyanide which is tested by the authoritative state level laboratory of environment test and analyst center in Chinalco Luoyang Copper Co., Ltd.(Chinalco) 2. Suitable technology It has superior performance, and it is been broadly used in heap-leaching, pool-leaching, mixing(carbon slurry ), the mine holes cleaning and etc. 3. Suitable Range It assure reliable quality, and it is suitable for oxidized ore, sulfate slag, gold concentrate, cyaniding tailings and etc. 4. Easy to use &convenient Can refer to the usage and amount directions of cyanidation, and simply adjust the PH value to 10-12. There is no need to replace equipment and technology. 5. Transportation& Safety storage According to the report of the Liming Research Institute of Chemical Industry claims this product does not belong to inflammable and explosive dangerous goods, store in a cool and dry condition and separated with acid substances. It can also conduct normal transportation: highway, railway, and ocean shipping. Instruction of Usage
1.The 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 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 It is similar to sodium cyanide method during the actual producing process. The barren solution can reuse and compatible with cyanidation. Add its 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 is not repelled with assistant potion: ammonium hydroxide, sodium sulfide, potassium ferricyanide, lead nitrate, sodium hypochlorite during complex ores pretreatment. e) It 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. 商品参数
