Abstract

Graphite is naturally floatable due to its hydrophobic property and also soft and smears on other gangue particles, rendering the gangue more or less floatable too. Due to this reason it is important to concentrate on areas such as suitable flotation reagents, depression agents, pH modifiers, and particle size to be fed during the process. The paper surveys and analyses the suitable particle size to be fed to achieve high-grade concentrate. According to the work carried out the author suggested the ideal cost effective flotation flow sheet for improved results at Bogala Mines in Sri Lanka.
