 | DSI’s Technical Expertise Needed for Re-Opening of Mexican MinePhosphate Rock Mine Rofomex, La Paz, MexicoPhosphate rock is the basic material for producing phosphate and thus the crucial component in the production of fertilizers. On the Pacific Rim, the only exploitable phosphate rock deposit is near La Paz, south of the Mexican peninsula, Baja California. Until 2001, phosphate rock had been exploited for the production of fertilizers in the Rofomex Mine. These fertilizers were then sold both on the Mexican and on international markets. The mine was closed in 2001 in the aftermath of a hurricane that severely damaged the port facilities and caused heavy rains that flooded the mine. In 2007, the owner decided to resume phosphate rock exploitation in this mine. The exploitation is carried out underground in a mine with room and pillar design, at an average seam height of 1.70m. |
