Flake graphite, its derivatives and graphene are ‘green’ materials:

Green Technologies Developed and Adopted in Madagascar:

Sand Production

Mining

Free Dig mining with zero blasting requirements – lean mining fleet and lower energy requirements.

Mining waste i.e., overburden is used for filling and levelling land in swampy areas and valleys, preparing land for habitation, farming etc for the locals.

Processing

Specialised equipments developed for flake graphite processing – a lean process, lower energy and material handling requirements

A unique equipment SAGE designed and installed – 50% waste from ore obtained as by-product construction sand.

>85% Recovery, negligible dust generation.

Treatment of tailings established for reconditioning and reuse of process water, obtaining clay for social development activities.

Feasibility study completed for establishing hydroelectricity facilities for meeting operational energy requirements
