The sulphur miners at Ijen extract about 14 tonnes per day, just 20% of the total amount of daily deposit. Several long steel pipes are sunk into the floor of the caldera to carry the red, molten sulphur to the surface. It then quickly solidifies, is broken into chunks and loaded into baskets. A load of 80-90kg is carried 3.5km to the nearest road and sold to a middle-man. Each miner will make the trip twice per day to earn about $8. Not surprisingly, chronic respiratory disease is common amongst the miners.
