Workers risk health hazards and arrest for small quantities of tin, which they say fetches more money than fishing or farming.

Rubber tubes are used to pump the sand from the ocean floor to the boat, where it is sorted for tin.

Tons of tinsand are melted into ingots, that are then exported via Singapore to Europe and China.

Tin from Bangka island eventually ends up as solder in millions of mobile phones, laptops and computers in Europe, US and Asia. Photograph: Marten van Dijl
