HYDROGEN PEROXIDE 50%

Hydrogen peroxide is used in the mining industry as an oxidant in various metallurgical processes, including ore leaching, concentrate preparation, and effluent treatment. It can improve process performance, reduce reagent and acid consumption, and simplify waste management. In gold mining, hydrogen peroxide can oxidize sulfide minerals, reducing cyanide consumption and enabling the use of alkaline amino acid-peroxide systems for gold leaching. It also plays a role in effluent treatment and cyanide management.
Here’s a more detailed look at its applications:
1. Oxidant in Metallurgical Processes:
Ore Leaching: Hydrogen peroxide helps dissolve metals from ore, potentially saving on acid and reagents.
Concentrate Preparation: It aids in the process of concentrating ore, improving efficiency.
Effluent Treatment: Hydrogen peroxide can be used to break down pollutants in mine wastewater.
2. Gold Mining:
Oxidation of Sulfide Minerals:
In refractory gold ores, hydrogen peroxide oxidizes sulfide minerals, which can then be readily leached with cyanide.
Alkaline Gold Leaching:
It can be used in alkaline amino acid-peroxide systems as an oxidant for gold leaching, potentially replacing cyanide in some cases.
3. Other Applications:
Wastewater Treatment:
Hydrogen peroxide can be used to degrade cyanide in wastewater, a common problem in mining.
Effluent Treatment:
It can be used in various steps to remove chemicals and improve water quality.
Cyanide Management:
Hydrogen peroxide helps break down cyanide compounds, making it a safe and efficient method for cyanide disposal and management in mining, especially in precious metals extraction.
4. Benefits of using Hydrogen Peroxide in Mining:
Reduced Environmental Impact:
Hydrogen peroxide can help minimize the use of other chemicals, like cyanide, which are known to have significant environmental impacts.
Improved Process Efficiency:
By oxidizing minerals and aiding in leaching, hydrogen peroxide can lead to higher metal recovery rates and lower operating costs.
Enhanced Safety:
In some cases, hydrogen peroxide can be safer than other oxidants or can be used in conjunction with other chemicals to reduce the risk of explosions or toxic gas formation.
