                  1. Suitable technology
                  Jinzhongpai has superior performance, and it is been broadly used in heap-leaching, pool-leaching, mixing ( carbon slurry ), the mine holes cleaning and etc.
                  1. Suitable Range
                  Jinzhongpai assure reliable quality, and it is suitable for oxidized ore, sulfate slag, gold concentrate, cyaniding tailings and etc.
                  1. 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.
                  1. Transportation& Safety storage
                  According to the report of the Liming Research Institute of Chemical Industry claims this product (Jinzhongpai) 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. Jinzhongpai eco-friendly gold leaching agent executive standard
                  Q/L YHD – 001 – 2015
                  1. 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.   
                  1. 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.
                  1. 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 Jinzhongpai potion.
                  1. Usage concentration
                  Base on the actual ingredients of ores, and achieve the optimum result by implement experiment to obtain the ideal concentration of potion.
                  1. Method of usage
                  Jinzhongpai is similar to sodium cyanide method during the actual producing process. The barren solution can reuse and compatible with cyanidation. Add the Jinzhongpai potion into the barren solution pool, rinse by backwater continuously to dissolve. If there is any black slag occurs, won’t affect further use.
                  1. Cautions
                  1. Recommend to use golden coconut shell as complement extraction potion to absorb carbon or zinc powder.
                  2. Recommend to test content level, PH value of the pregnant solution, and concentration of gold-leaching agent .
                  3. The strong oxidant such as hydrogen peroxide, potassium permanganate is not recommended to put together with gold leaching agent(can do some pretreatments).
                  4. It (Jinzhongpai) is not repelled with assistant potion: ammonium hydroxide, sodium sulfide, potassium ferricyanide, lead nitrate, sodium hypochlorite during complex ores pretreatment.
                  5. Jinzhongpai is not repelled with sodium cyanide if use both at the same time.
                  6. The’ oxygen-rich leaching process ‘ of all-slime cyanidation CIP technology has negative influence on the gold extraction agent(Jinpingpai).
                  Test Method of Jinzhongpai concentration
                   
                  1. Equipment
                  500ml conical flask@1, 10ml pipette @2, read head dropper @1 
                  1. Reagent
                  Developer : put Jinzhongpai concentration color developing agent into 500 ml acetone solution, shake well for use.Detection reagent: put Jinzhongpai detection reagent into 1000ml distilled water, shake well for use.
                  1. Test procedure
                  1. Use pipette to get 10ml of test solution, and put it into 500ml conical flash;
                  2. Drop 3 drops of developer, and shake it well until the liquid become yellow.
                  3. To start titration by using pipette to get 10ml detection reagent. In the meanwhile shake it gently, and observe the transformation of liquid color in the conical flask. Read the consuming millimeter of detection reagent once achieve red liquid color.
                  4. Concentration conversion:
                  Jinzhongpai concentration = (X ÷2)‰ , if consumes 2ml of detection reagent, then the Jinzhongpai concentration should be one per mille.
