Summary
DescriptionSulfur mining in Kawah Ijen - Indonesia - 20110608.jpg |
English: Sulfur mining in Kawah Ijen volcano, Java, Indonesia. At the upper left of the picture, the sulfur, yellow and orange, is emitted as yellowish vapor and forms crystal concretions on the rock face of the crater. Big pipes capture vapor at ground level to facilitate the extraction. To condense the hot vapor, water is supplied through a pipe from a small pond at the bottom right, then thrown with buckets on the pipes carrying the vapor to cool them. In the left half of the picture, miners carry sulfur blocks in wicker baskets. To protect themselves against toxic vapors that pervade this part of the crater, they wear masks or simple rags. The baskets are then taken to a flat area on the right. Afterwards, workers carry them on their shoulders up to the rim of the crater, then down the side of the volcano to a place trucks can access. The trucks finally deliver the sulfur to a processing plant. Français : Mine d'extraction de minerai de soufre dans le cratère du Kawah Ijen, île de Java, Indonésie. En haut à gauche de l'image, le soufre, en jaune et orange, est émis par les vapeurs jaunâtres et se dépose sur les parois du cratère en concrétions cristallines. De gros tuyaux ramènent ces vapeurs au niveau du sol pour faciliter l'extraction. Pour précipiter la formation des cristaux, de l'eau est amenée par une canalisation depuis une petite mare en bas à droite, puis jetée par seaux sur les tuyaux. Dans la moitié gauche de l'image, on peut voir les mineurs mettre les blocs de soufre dans des paniers en osier. Pour se protéger des vapeurs toxiques qui envahissent cette partie du cratère, les ouvriers portent des masques ou de simples chiffons. Les paniers sont ensuite amenés jusqu'à une zone plane à droite. Des porteurs les montent ensuite sur leur épaule jusqu'en haut du cratère, puis redescendent le flanc du volcan jusqu'à l'endroit où les camions peuvent accéder. Ces derniers emmènent alors le soufre jusqu'à une usine de transformation du minerai.
