Metal ore recovery

Frother for metal ore flotation

Methyl isobutyl carbinol (MIBC) is an organic chemical compound that acts as foaming agent in the flotation process to separate metal concentrate from the slurry. MIBC is the frother of choice for sulfide ores such as copper, zinc and lead, because it is able to deliver optimal interaction of all components in the flotation process. 

Oxidizing agent for metal extraction and separation from ores

Albone®  is a hydrogen peroxide solution that acts as an oxidizing agent in metal extraction and separation from ores. Compared to alternative treatments, Albone® main advantages are the simplicity of use and a much lower effluent production. Albone® is useful in precipitating or separating metal from solutions in the recovery processes for base metals (Copper, Lead, Zinc, Cobalt), precious metals (Gold, Silver, Platinum) and rare earth metals (Uranium, Radium, and Beryllium). 

Alpure®​ is a sodium chlorate is an oxidizing agent for the metal leaching process. Sodium chlorate makes the mineral concentrate more soluble in water.
