Briefing
Eco-friendly cyanide-free gold leaching reagent for high gold recovery, suitable for heap leaching, CIP and CIL processes.
Detailed
What is Metallic Ore Dressing Agent
Metallic Ore Dressing Agent is a new high-tech product which is used in gold benefaction as the substitute for sodium cyanide.
Core Features
1.It is formulated to be non-toxic and to minimize the environmental impact associated with traditional gold extraction processes by cyanide and the only patented product for “environmentally friendly gold extraction”around the world.
2.It can be employed without changing original process and equipment.
3.Wide application range: It is suitable for the flotation of various sulfide minerals such as copper, lead and zinc.

Application
1）Applicable ore types: golden and silver oxidized ore, semi-oxidized ore，primary ore, high-sulfur and high-arsenic gold ore, cyanidation slag, flotation gold concentrate, fine-grained gold ore，cyanide tailing，pyrite cinder，electronic circuit board and anode mud etc;
2）Applicable beneficiation process: heap leaching method，pool leaching method，carbon slurry method etc;
3）Dissolution Method: it can be used after being fully dissolved by water under normal temperature (in general, the dissolution can be accelerated in flowing water or through full stirring; dosing pool can be built near to the barren solution pool in heap leaching process in order to let backwater which has passed carbon directly wash Golden Cicada and dissolve it into barren solution pool);
4）Alkalinity Adjustment: in general, adjustment is carried out with lime or caustic soda with stable pH value between 11-12;
Applications & Solutions
heap leaching method

FAQ
Some points on using eco-friendly gold leaching reagent：
①It is recommended to used special golden coconut shell absorption carbon or zinc dust as the auxiliary absorption agent (special activated carbon special for carbon pulp gold extraction is used in the CIP process);
②The best effect will be obtained when Golden Cicada is used at the temperature of more than 15℃;
③The gold leaching speed is relatively big, so it is recommended to detect pregnant solution grade, pH value and Golden Cicada concentration at regular time;
④It is not recommended to put in strong oxidizers such as hydrogen peroxide and potassium permanganate together with Golden Cicada (pre-treatment can be made);
⑤The use of ammonia water, sodium sulfide, potassium ferricyanide, lead nitrate and sodium hypochlorite as well as other subsidiary medicines in complex ore pre-treatment does not reject Golden Cicada gold leaching;
⑥A little of black slag generated after dissolution of Golden Cicada will not affect the leaching effect;
⑦Golden Cicada and sodium cyanide will not reject each other when being used at the same time;
