SHANGHAI, Aug 24 (SMM) – This is copper news roundup for last week.

1. Codelco said that the third group of workers at the Andina copper mine in central Chile began a strike on August 17, bringing the number of strikers in the sector to more than 1,000. After the Suplant union members voted to reject the offer made by the management after mediation and negotiation, they started an indefinite strike at 8 am local time. Earlier, members of the SIIL and SUL unions of the copper mine started a strike on August 12 after salary negotiations failed. Andina produced 184,437 mt of copper concentrate last year, and production of open-pit mines and underground operations have stopped due to the strike. Codelco plans to commission the $1.4 billion Andina transfer project later this year, which will relocate the primary crusher plant to expand the sector’s open-pit mining operations. However, this year's high copper prices have led the union to demand higher participation in the lucrative profits of the mining company.
