At BMPA, members are encouraged to do backfilling – the waste sand from the mineral processing sites is carried back to the mining area for refilling the sites, so that the natural topography is restored.
The entire process is eco-friendly and energy efficient. Heavy mineral concentrate separated from the deposit is sun dried manually and requires no additional sources of energy. Harnessing natural solar power to dry the concentrate saves 133kg of carbon dioxide for every ton – that is nearly 100,000 tonnes in a year.
As there are no chemicals used at any point, there is no toxic discharge. Sea water is used in the concentration plants, saving precious fresh water of about 1600 litres per ton of concentrate – that is 1.2 million kilo litres a year!
