Hydrogen peroxide is a bleaching agent with a diverse number of uses in mining and metallurgy, textiles as well as pulp and paper manufacturing.

We offer two main grades of hydrogen peroxide, 50% and 60% which can be quite safely interchangeably used in the above processes. Our hydrogen peroxide serves as an effective pure bleaching agent. 

It can be packed in 30kg containers which are easy to handle, or 1m3 containers normally used in textiles and in pulp and paper making.


The Elsner Equation for the dissolution of gold below requires oxygen to speed up reaction kinetics.One important source of oxygen for use in leaching is hydrogen peroxide. Peroxides are generally unstable and decompose into water and oxygen according to the reaction below:


  2 H2O   ------>    2 H2O  + O2


Gold dissolution rates are thus directly related to the amount of dispersed oxygen in the leach tank.


  • Alternative sources of oxygen include compressed air and pure oxygen. Even at plants using these, there is need to have an inventory of hydrogen peroxide for use should there be any compressor breakdowns or delays in delivery of oxygen tankers.
  • The other advantage of the use of peroxide is that there isn’t any major CAPEX investment involved.


Dosage rates for peroxide increase with increased complexities of leaching of various feed material. Material that needs more peroxide includes sulphides and dump recycled material whilst oxide ores are generally easy to leach and thus need less peroxide dosages during cyanidation.


60% or 50% peroxide can be used for mining purposes, though the 50% specification is normally used for this.


60% of global hydrogen peroxide output is used for pulp and paper bleaching especially in bond paper manufacturing plants. These normally take 50% or 60% peroxide specification.

Hydrogen peroxide is also used to make sodium percarbonate and sodium perborate which are bleaches used in laundry detergents


It also finds use in specialized water treatment plants were it used to deal with organic impurities


Hydrogen Peroxide 35% finds use in the food industry, cosmetic industry and also has medicinal usage.

Method of Application

Hydrogen peroxide is dosed as is straight into the leach tank or into leach conditioning tank.
