Abstract

The Takua Pit Thong mine, Rajburi, is situated along the border with Bunna, about
200 km W of Bangkok. Mining started 18 years ago for tin which occurs with
arsenopyrite near the contact between a granite and metamorphosed country rock.
Pegmatitic veins associated with the granite are rich in microcline and microcline
perthite. Beneficiation testwork on the granite and its associated pegmatitic phases by
the Department of Mineral Resources (DMR), Bangkok, three years ago in response to
the growing need for ceramic feldspar in Thailand, established the viability of feldspar
production. At present, tin production (72% Sn) is running at about 9 tonnes/month
and saleable feldspar concentrate in excess of 300 tonnes/month.
