Dr. D. Padmalal is a research scientist at the Centre for Earth Science Studies (Trivandrum, Kerala, India). He is an expert in Quaternary Geology and Environmental Geology and has been studying sand mining and related environmental problems for almost 20 years.
The process was labour intensive with miners digging through the top layer of sand to extract the rich black mineral sand below. By the 1960s these concentrations had been exhausted and the miners moved their operations to the foredunes. Beach mining was hard work with between 25 and 30 men working in teams to shovel sand as fast as they could.
