Abstract:
Mining industries face a challenge of high levels of cyanide in mine tailings. Cyanide is a strong
binder for complexating with virtually heavy metal. This complexation with heavy metal can
inhibit all biochemical processes resulting in human organ failure and even death. Research has
it that remediation has always been chemical methods for example addition of oxidants and
complexing agents such as ferrous sulphate which in the long run cause secondary pollution.
Phytoremediation utilizes the equations of data analysis to measure the cyanide concentration in
soil. It also uses the Friedman statistic to determine if there are statistically significant
differences in cyanide concentrations across the stages of growth of the lima beans.
This project rendered significant advantages such as significant potential of lima bean in
improving soil health, nitrogen-fixing capability, the enhancement of the biological, chemical,
and physical properties of the soil, organic matter, and soil structure, and in reducing soil bulk
density, increasing soil water holding capacity, and promoting soil microbial diversity and
activity, leading to enhanced soil ecosystem stability, thus enhancing soil quality. By
demonstrating the feasibility and effectiveness of this method, the project aims to contribute a
safer, more sustainable mining environment.
