Project Scope

The Grasberg Open Pit Mine located in Indonesia is the largest gold mine and third largest copper mine in the world, owned by PT Freeport Indonesia.

The crushed ore is transported to the mill stockpiled via the 4.9km inclined conveyor system with a 19,500 kW installed motor power.

The mine produces 600,000 tonnes of copper, 55 tonnes of gold and 170 tonnes of silver per year.

PROK engineered, manufactured and supplied 30 conveyor pulleys for the DMLZ project in Paupa, Indonesia. PT Freeport needed conveyor pulleys that require low ongoing maintenance, as maintenance underground in confined spaces is more difficult and time consuming.

Project

Roy Hill – ROM4 Mine Expansion

Roy Hill is a world-class iron ore operation located in Western Australia’s Pilbara region that delivers around 60 million tonnes per annum of iron ore. As part of their ROM4 mine expansion, Roy Hill constructed a new overland conveyor system totaling over 8km in length. PROK was selected to manufacture and supply the idlers for the new system. PROK was awarded the contract for the conveyor idlers off the back of a long history of success with various overland conveyor systems across the globe. Roy Hill required the new overland conveyor to connect a new crusher to the existing mine infrastructure. The system comprises 2 overland conveyor systems approximately 8km in length. The entire project scope for the conveyor components included the manufacture and supply of 23,500 rollers and 6,500 idler frames. The majority of the rollers will be PROK HDPE, our market-leading, lightweight composite roller. PROK HDPE was chosen due to its lightweight construction and exceptional reliability. The rollers include dual-layer wear indicator technology which facilitates smarter roller maintenance. Over 17,000 rollers are PROK HDPE, our market-leading, lightweight composite roller with dual layer wear indicator technology.

FMG – Iron Bridge

Fortescue is one of the world’s largest producers of iron ore. Their new mining hub - Iron Bridge produces magnetite. Global conveyor components manufacturer PROK has been awarded a major contract for the design, manufacture and supply of conveyor pulleys at the Iron Bridge Magnetite Project, a joint venture between Fortescue Metals Group subsidiary FMG Iron Bridge and Formosa Steel IB Pty. Ltd, near Port Hedland in Western Australia. PROK will design, manufacture and supply around 170 complete pulleys from their Bayswater production facility in Perth, Western Australia. The pulleys will be installed across 25 new conveyors at the Iron Bridge site.

Project

Teck Resources – QB2

Teck’s Quebrada Blanca Phase 2 (QB2) project will be one of the largest copper operations in the world and will be developed under the current Quebrada Blanca operation deposit. PROK Chile was engaged for the manufacture and supply of 57 engineered pulleys for the project. The dimensions range from 450mm to 2000mm in diameter. PROK pulleys are Designed with years of industry advancement and infinite fatigue life criteria. These pulleys delivered to QB2 will assist with maximising uptime and reducing their total cost of ownership.

Project

Rio Tinto – Kennecott Copper

PROK was contracted for the manufacture and supply of PROK heavy duty engineered pulleys and over 13,000 PROK Flow Formed rollers. The 4 non-drive pulleys weighed approximately 25 tonnes each, with a diameter of 1800mm. The dual drive pulleys weighed around 36 tonnes each, with a diameter of 2000m. Rio Tinto Kennecott is a copper mine located just outside Salt Lake City, Utah, US and wholly owned by Rio Tinto. The Kennecott site has been operational for more than 100 years, mining and processing minerals from the rich orebody of the Bingham Canyon Mine. In 2020, the site undertook significant upgrades and expansion to its minerals processing infrastructure which included moving an existing crusher which meant there was a requirement for a new overland conveyor.
