Biopolymer

Used for precious metal processing

Application

Processing of precious metals in leaching tanks.

Benefits

Accelerated reaction times using existing kinetics.

Recovery efficiency can be increased up to 3%.

Reduced cyanide use by up to 35%.

Replacement of the alkalizer used in the process and use of dosages up to 20x lower.

Stability of the desired pH during the process, avoiding oscillations common with the use of other alkalizers.

A cleaner process can produce tailings with lower levels of toxicity.

Allows the use of gold and precious metals with higher purity.

No additional special equipment required.

Efficacy easily validated in your laboratories.

Scalable using your existing tank injection configuration.

The chemistry of MetaFLO biopolymer is designed for the cyanidation process to achieve improvements in the gold leaching step. In addition to acting as an alkalizer in the process, by reacting with the heavy metals associated with gold, MetaFLO's biopolymer can increase gold extraction percentages by up to 3%.

How Does It Work?

ExtracTech chemically performs two functions when in contact with the ore: as an alkalizer, adapting the pH of the pulp to the desired range and bringing its stability throughout the process and also acts as a chemical oxidant performing oxidation reduction reactions with the other metals present in the gold matrix, eliminating them.

ExtracTech also provides additional oxygen to the reaction, allowing the reaction itself to be accelerated

The cyanide cannot see the gold before being exposed, so it needs to react with the metals on the surface first to then be able to see the gold.

Cyanidation-with-having-ExtracTech-added

ExtracTech, by reacting with the metals associated with the gold particles, facilitates the action of cyanide in the process.

It will react in the order of metal reactivity and break the bonds, releasing energy in a slightly exothermic reaction.

It will react more quickly with non-metals and with metals with high oxidation-reduction potential (ORP), such as iron.

ExtracTech has been successfully tested in gold mines, achieving benefits such as alkalizing replacement, increased metallurgical recovery and reduced cyanide consumption

Before ExtracTech Reaction

After ExtracTech Reaction

Application of ExtracTech in refractory gold ore with palladium and platinum.

Much lower dosages are required than traditional alkalizers, in addition to maintaining the stability of the desired pH range.

As a Biopolymer for cyanide reduction

As an additive to your existing cyanidation process, ExtracTech can also reduce your cyanide usage by up to 35%.
