Engineering at Metalliferous Mines 

For the Metalliferous Mining sector, North Queensland remains an ideal location for further mineral discoveries and is currently Australia’s largest producer of zinc, lead and silver.  The region also ranks highly for copper, bauxite and gold. Other important minerals mined in Queensland are cobalt, nickel, phosphate rock, magnesite, magnetite, molybdenum, rhenium, scandium and tin.  Minerals are extracted and recovered through underground and open cut mining operations and processed using onsite processing plants.

Orana Engineering has been engaged by a range of metalliferous mining clients throughout Queensland, with engineering experience in the mining, processing and storage of lead, silver, zinc, gold and copper.  Our clients value our industry knowledge and experience, as well as our practical North Queensland location, allowing our team to be reactive and offer local, hands-on support.  We understand the importance of compliance within the metalliferous industry, with our staff keeping up to date with all relevant legislation including the Mining and Quarrying Safety and Health Act and Regulations.  Further information on the Act and Regulations can be found below. 

Mining and Quarrying Safety and Health Act 1999
Mining and Quarrying Safety and Health Regulation 2001

We are well equipped to offer mechanical, electrical, structural and control systems engineering services for the metalliferous mining industry, assisting with engineering for fixed plant, processing plants, conveyor belts, concentrators and site infrastructure.  Explore the case studies below to learn more about the value we have added for our metalliferous mining clients.  

ORANA ENGINEERING MetalLiferous Mine Engineering

F100 Reagent Modifications

Orana Engineering was engaged by MMG’s Century Mine in Western Queensland to perform an engineering review of a proposed reagent dosing system within the concentrator. more

Cyanide Tank Upgrade

In recent years Orana Engineering has enjoyed a productive relationship with Resolute Mining Ltd through its subsidiary Carpentaria Gold by undertaking several projects at their Ravenswood site. Sodium Cyanide is a very toxic compound used on site to recover gold from prepared ore. It is potentially lethal to humans and animals and can be extremely detrimental to the environment. more

Sag Mill Cover

BHP Billiton Cannington Mine, located in North West Queensland is a significant miner and exporter of Silver and Lead concentrate via the Port of Townsville. Orana Engineering was engaged by Cannington site maintenance to provide workshop fabrication drawings for a replacement cover to address the issue of corrosion that was present around flanges and access openings on the existing Sag Mill Trommel Sump Cover. more

Inner Bypass Valves

Orana Engineering was engaged by MMG’s Century Mine in Western Queensland to investigate and design an upgrade within the concentrator to increase flow from a flotation cell to a tailings trough. more

Heavy Vehicle Washdown Facility

MMG’s Karumba Port Facility engaged Orana Engineering to design a heavy vehicle washdown facility to assist with management of concentrate for vehicles and machines used onsite. The project time frame was very short due to operational requirements, whereby Orana Engineering had to work from concept to IFC drawings within 7 days. Orana Engineering’s quality assurance system allowed the design to be completed quickly whilst ensuring a high level of quality for our client. more

FB-028 Tank Lifting Beam

During an upgrade to the Concentrator at MMG’s Century Mine located in Western Queensland, Orana Engineering was engaged to design a lifting beam for the installation of a new flotation cell. more

Mill Gear Box Frame

The IMT project team at MMG’s Century Zinc operations enlisted the assistance of Orana Engineering to produce a set of fabrication drawings for an existing gear box frame which required replacing. Although the frame itself had been in operation for quite some time, there were no detailed drawings available that could be used for the construction of a replacement unit. more

Ball Mill #2 Recommissioning

Eloise Copper Mine (ECM) had a requirement to recommission their No.2 Ball Mill. During the process of the recommissioning works it was identified that a means to relocate the grinding media to the feed chute needed to be designed and engineered with RPEQ certification. more

Jaw Crusher Platform

Eloise copper mine is an underground mining operation producing copper concentrate for export. The maintenance department of Eloise Copper Mine contacted Orana Engineering with a specific requirement for the design of an access platform for their jaw crusher including engineering certification and drafting. The client provided Orana Engineering with site measurements and a basic concept of the design they were looking for. more

Flotation Cell Upgrade

In an effort to increase the efficiency of their concentrator, Eloise Copper Mine enlisted the services of Orana Engineering to provide engineering and design assistance for the installation of 3 new copper concentrate scavenger cells, within the existing processing plant. more

Crusher Circuit Upgrade

Eloise Copper Mine had purchased a new Metso TS4.2 dual deck vibrating screen to replace the existing smaller screen and a second Omnicone cone crusher to provide a secondary crushing circuit to increase their production and improve operational efficiencies. more

Tank Static Line

All mine and industrial sites will list safety as their highest priority within their day to day operations. In line with this philosophy, management at Carpentaria Gold’s Ravenswood Operation enlisted the assistance of Orana Engineering to design a fall arrest system that could be easily removed and repositioned above the multiple leach tanks on site to allow for the safe removal and servicing of tank agitators. more

Gold Slurry Sampler

Orana Engineering was engaged to design a new sampling equipment installation to improve sampling effectiveness at Carpentaria Gold’s Ravenswood operations. more

TK102 Bypass Piping

When tasked with a major repair to one of their leaching tanks, operations staff at Carpentaria Gold’s Ravenswood Operations enlisted the assistance of Orana Engineering to develop a solution that would allow for process operations to continue whilst leaching tank TK102 was out of service. more

Water Polishing Plant Access Platform

The BHPB Cannington Port Storage Facility located at the Townsville Port operates a Water Polishing Plant for the treatment of site stored water. The Water Polishing Plant Filtration system requires regular maintenance in order to replace Filtration Rods. With the Filter Bank maintenance ports being at a level that cannot be accessed from ground level, it was necessary to arrange work platforms to perform this maintenance. more
