SMM7 4: Chile's national mining company (Codelco) once again postponed its Chuquicamata smelter's comprehensive resumption of production plans.

The company said that the smelter is currently in a state of local operation, including a flash furnace and an acid plant, and the second acid plant will resume normal operation within 6 days, and the full normal production of the smelter is expected to resume in the third quarter.

Rolando Milla, the No. 3 union president of the Chuquicamata copper mine, expects the smelter to resume full capacity by mid-August.

The smelter has been closed for seven months mainly because it failed to meet stricter environmental standards that came into force in December.

And as a result of Codelco's cancellation of its contract with SNC Lanwanling in March to build two new acid plants in the smelter at the Chuquicamata copper mine, the full resumption of production at the smelter has also been delayed.

At the time, Codelco said SNC Lan Wanling had repeatedly committed serious violations of the contract, including delays in payment to subcontractors, delays in construction and quality problems with the project.

Superposition of the previous Chuquicamata copper mine miners carried out a two-week strike, but also affected the normal progress of the project. After the end of the strike, the company is restoring production capacity to normal levels as soon as possible.
