Here's a List of Copper-Producing Regions in Indonesia, One of the National Mining Flagships

This smelter is expected to process 1.7 million tons of copper concentrate to produce 600,000 tons of copper cathode per year.

In addition to copper, this smelter can also produce up to 50 tons of gold per year and 150 to 200 tons of silver per year.

Other by-products from this mine include 1.5 million tons of sulfuric acid, 1.3 million tons of copper slag, and 150,000 tons of gypsum per year.

2. Mimika, Papua

Mimika was the largest copper-producing region in Indonesia before PT Freeport Indonesia built a smelter in Gresik.

Still owned by PT Freeport, the Mimika copper smelter's average annual production capacity reaches 670,000 tons.

According to a 2019 report, this Papuan mine produced 607 million tons of copper, increasing to 809 million tons in 2020.

3. North Sulawesi

North Sulawesi is also one of the largest copper producers in Indonesia and is managed by PT Vale Indonesia.

This region is reported to produce up to 693,109 tons of copper per year, which is then used for domestic needs and exported internationally.

North Sulawesi has 19 smelters spread across the region. Remarkably, not only copper but also gold, sand, iron, and coal are also found there.
