Engineering at Metalliferous Mines

Eloise Copper Mine purchased a Metso dual deck vibrating screen to replace an existing smaller screen and a second Omnicone cone crusher to provide a secondary crushing circuit for increased production and efficiency. Orana Engineering was engaged to develop a design solution and detailed drawings for the secondary crushing circuit which utilised as much existing equipment as possible. Orana Engineering was able to provide an efficient, practical design solution while minimising the associated design costs to provide site personnel with information required to refurbish and install the conveyor equipment necessary for the crushing circuit. Orana Engineering successfully completed the design within a tight project time frame and produced in excess of 100 detailed drawings.

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.

Orana Engineering was engaged to design new sampling equipment for improved sampling effectiveness at Carpentaria Gold’s Ravenswood operations. A site visit was undertaken by Orana Engineering design staff to accurately record critical data. This enabled designers to produce a detailed 3D model which was used extensively during interactions with the client and ensured a fluent understanding of the project scope by both parties throughout the design process. Orana Engineering was able to integrate new sampling equipment into the existing plant whilst minimising any impact on the operation. Various challenges were overcome with the result being successful delivery of drawings for fabrication and installation of equipment, allowing improved sampling and production reconciliation whilst minimising impact to operations.

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.

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.
