Mexico: Second Solar Process Heat Case Study on Copper Mining

Submitted by Baerbel Epp on December 1, 2016
Mexico Copper MineArcon-Sunmark has announced the completion of a second solar-heated copper mine project. In September 2016, the Danish company installed a 6,270 m² collector field (4.4 MWth) at La Parreña in central Mexico. A 30 September press release said that the solar field would cover 58 % of the mine’s demand for heat. The field consists of 456 components of nearly 14 m² each and a storage tank of 660 m³. The first project of its kind, a field of 39,300 m² (27.5 MWth), was completed with a joint-venture partner at the Gabriela Mistral mine in Chile in 2013. Being the world’s largest solar system for process heat application, it had produced 142,000 MWh in the first 35 months of operation, the press release said. This corresponds to a specific yield of 1,112 kWh per m² and year.
