Primero was engaged by PT Bumi Suksesindo (BSI) to complete the detailed design and procurement for the
Ore Preparation portion of the Tujuh Bukit Heap Leach Gold Plant. The plant is located in Indonesia, specifically Banyuwangi Kabupaten in the province of East Java and consists of a 4Mtpa heap leach pad and processing facility to produce gold and silver.

 

The ore preparation plant process consists of a two- stage open circuit crushing plant and agglomeration circuit. Stockpiled agglomerated ore is reclaimed and loaded into haulage trucks for delivery to the heap leach pad. The plant is located on the side of a steep embankment with a total fall of 65m over a linear distance of only 240m. This challenging terrain created a unique set of difficulties requiring an innovative design approach. Primero’s solution consisted of ten cascading process pad areas following the natural ground contours.

 

The resulting pads limited the amount of earthworks and provided an optimised process layout. The project scope included civil, structural, mechanical, electrical and control systems design in addition to vendor
procurement and management.

 

Primero utilised a 3D Building Information Modelling (BIM) design process to streamline the flow of information from Primero to local installation contractor. A hybrid system of smart 3D models in conjunction with traditional 2D drawings were transferred to the local contractor to compress the design schedule, reduce the number of design hours and decrease the chance of errors between design and construction. Innovation through engineering process improvement and industry leading Safety in Design resulted in a successful multi-discipline design delivery.
