Reliable Easy To Use And Environmentally Friendly Gold Leaching
Agent
Environmentally friendly gold leaching agents are environmentally
friendly alternatives to traditional sodium cyanide for gold
extraction, designed to reduce environmental pollution and
ecological hazards during gold mining. Their core ingredients are
typically low- or non-toxic inorganic or organic compounds, such as
thiourea, thiosulfate, sodium polysulfide, halide systems, or
specific environmentally friendly chelating agents.
Instruction of Usage
1. Environmentally Friendly Gold Leaching Agent Implementation
Standard
Q/LYHD-001-2015
2. Applicable Production Processes
Applicable to granular oxidized gold and silver ores. Production
processes include heap leaching, tank leaching, mixing,
carbon-in-slurry leaching, and mine cleaning.
3. Product Form
This product is available in solid block or powder form and is
readily soluble in water. It can be used immediately after
dissolving in water.
Main Ingredients: Sodium oxide, iron carbide, nitrogen, ammonium,
calcium, etc.
4. pH Adjustment
During production, first adjust the return water pH to 11±1 with
caustic soda or quicklime before adding this solution.
5. Usage Concentration
The optimal solution concentration should be determined
experimentally based on the actual ore composition.
6. Usage Instructions
In actual production, this method is similar to the sodium cyanide
method. The barren solution can be reused and is compatible with
the cyanide method. The barren solution from this method is added
to the barren solution tank and continuously rinsed and dissolved
with return water. If black residue is produced, it will not affect
subsequent use.
7. Precautions
a) It is recommended to use golden coconut shells as a
supplementary extractant to absorb carbon or zinc dust.
b) It is recommended to test the content, pH value, and
concentration of the gold-rich solution.
c) It is not recommended to mix strong oxidants such as hydrogen
peroxide and potassium permanganate with the gold leaching agent
(partial pretreatment is acceptable).
d) During the pretreatment of complex ores, this method is
incompatible with auxiliary agents such as ammonium hydroxide,
sodium sulfide, potassium ferrocyanide, lead nitrate, and sodium
hypochlorite.
e) There is no repulsion when used with sodium cyanide.
f) The "oxygen-enriched leaching process" of the full-slime cyanide
carbon-in-pulp method has a negative impact on gold extractants.
