Gold is immobile and insoluble in soil. However, it can be mobilised by cyanogenic plants and microbial activity. (Sheoran et al., 2013) Gold is soft acid in its cation form. It could bind with soft base like S and N. It can be absorb by root plant. Distribution (Trichome, epidermis, mesophyll, cell wall and vacuoles) Detoxification (Chemical conversion, complexation with amino acid) Sequestration (Vacuoles) Transported using xylem After bio activation, Root exudates, micro-

SLIDE 19

PHYTOMINING IS

RELIABLE METHOD

Phytomining is economically and technically reliable to be used in low concentration gold metal.

ECOFRIENDLY METHOD

Phytomining could reduce significantly environmental damage that might cause by surface mining method.

INDUSTRIAL SINERGIES

This method can include some related disciplines to research suitable plants for application.

BIOMASS ENERGY

In line with gold extraction, it can also generate another source of energy, for example biomass.

PUBLIC ACCEPTANCE

Phytomining will be accepted by most people.

SUSTAINABLE MINING

It has almost sustainable mining parameters and compatible with the demand

f green economic campaign

FURTHER STUDY

It is suggested to study plant genetics to improve plants extraction performance.
