INDONESIA – New Moly Cop plant operating

PT Commonwealth Steel Indonesia, also known as Moly Cop Indonesia, has started operating a new steel ball plant in Cilegon, Banten. The plant, built at a cost of US$24 million, will annually produce 50,000 tonnes of forged mid-size steel balls when at full capacity.

These balls are used in the grinding of mineral ores and other particulate materials. In the initial phase, the plant will operate at half of its total installed capacity. The company’s president director Adrian Boltong said this could be increased later in line with market demand.

The plant will supply major customers, such as PT Freeport Indonesia and PT Newmont Nusa Tenggara, as well as a number of smaller miners.

“We are currently importing steel balls of this size from Australia,” Adrian Boltong said. Moly Cop will primarily source raw material from Indonesia’s biggest steelmaker, PT Krakatau Steel, and the rest from overseas.

The plant is Moly Cop’s second Indonesian facility with the first located close to the new one. This plant has been operating for about 20 years and makes 30,000 tonnes of small-sized steel balls annually. The grinding media made by the Cilegon plant is used widely throughout Asia, primarily in mining operations that extract copper, iron ore and gold.

Moly Cop is a subsidiary of Arrium Group, an ASX-listed diversified mining and materials firm. Its grinding-ball manufacturing business spans seven countries – Australia, Canada, Chile, Indonesia, Mexico, the US and Peru.

Adrian Boltong told local media that due to long-term business prospects in Indonesia, the company plans to build another facility to manufacture bigger-sized grinding balls.
