Indonesia is a major producer of copper ore, with an estimated reserve of 270 million tons. The country’s copper ore is mainly found in the provinces of Papua, West Papua, and Sulawesi.
After a sharp decline in 2017, Indonesia's copper production is estimated to have recovered by 5% to 653.4 thousand tonnes (kt) in 2018. The increase was primarily supported by an 18% rise in production from the Grasberg minerals district, which hosts the Grasberg Open Pit, the Deep Ore Zone, the Big Gossan, and the Deep Mill Level Zone …
The resulting solution is processed through solvent extraction and electro-winning. These researchers from MIT found a way of extracting liquid copper metal and sulfur gas from an electrolyte made up of barium sulfide, lanthanum sulfide, and copper sulfide, yielding over 99.9 pure copper.
The ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. Grasberg's milling and concentrating complex is the largest in the world, with four crushers and two giant semi-autogenous grinding (SAG) units processing a daily average of 240,000t of ore.
The laborious task of mining copper ore by hand made obtaining large quantities for production difficult. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a considerable increase in copper production, with mines smelting between 200 and 300 tons of copper ore per week.

Adding another SAG mill to the two existing ones at the mill. A SAG or semi-autogenous mill uses steel ball and the ore itself to break up the rock into fine particles in order to separate the copper and gold from all the non-valuable constituents of the ore, or gangue. Before 2019, the mill could operate at 250 ktpd.
Fluor Corp. (Irving, Tex.) announced that its joint venture with Petrosea – Fluor Petrosea Joint Organization (FPJO) – has been selected by PT Freeport Indonesia to install a new grinding mill at its Grasberg copper and gold mining district in Papua, Indonesia.
