The mine is located 1,530 kilometres (950 mi) east of the Indonesian capital Jakarta on Sumbawa, in southern Taliwang regency, an island in West Nusa Tenggara. The mine is the result of a ten-year exploration and construction program based on a 1999 discovery of the porphyry copper
The mill produces copper and gold concentrate from mined ore through a process to separate valuable minerals from the impurities covering them. The main steps in the process are crushing, grinding, flotation, and dewatering. Crushing and grinding transform ore size into fine sand in order to release particles containing copper and gold.
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 240,000 tonnes of ore in 2006.
The “ball and chain” provided a simple guide to stacking height such that once the copper ore reached the ball the plant operator would move the stacker slightly to the side and continue stacking. Consistent stacking of the ore height improves the copper ore heap leaching process in several ways. A well-stacked heap reduces ponding once
ball mill indonesia copper ore classifying mining. Indonesia currently produces around four percent of the world's gold production due in large part to the Grasberg mine. It is estimated the mine contains the world's largest gold reserves (67.4 million ounces). Large scale mining companies operating in Indonesia include: Freeport McMoran (the majority owner of Grasberg), Newcrest Mining, and

Results of using this advanced controller on a ball mill circuit operation in a copper concentrator are presented. The controller stabilized the mill operation and resulted in a 4.18% throughput increase in ground ore that is finer than the desirable size. INTRODUCTION In the past fifteen years, model-based control techniques have been successfully used in the process industry. These
Copper Mountain’s concentrator was commissioned in May 2011. The circuit consists of a 34’ x 20’ EGL SAG mill, a Raptor 900 pebble crusher and two 24’ x 39’6” ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From
