Tujuh Bukit Gold Project – Wet Plant Design and 8 Mtpa Upgrade

Como Engineers, in partnership with PT Como Engineers, completed two stages of work at Tujuh Bukit: the detailed design of the 4 Mtpa plant, and the subsequent upgrade to 8 Mtpa.

4 Mtpa plant: Como Engineers delivered the detailed design for the 4 Mtpa plant.

Upgrade to 8 Mtpa: Como Engineers and PT Como Engineers completed the upgrade to 8 Mtpa, along with the design of a clarifier and filter circuit for the detox circuit.

Overall works across the project include CIC trains capable of treating 550 m3 PLS flow each, a 550 m3 CIC scavenging train designed to reduce gold losses prior to detox, a 6 tonne split AARL elution circuit, gold room and off gas scrubbing, and a detox circuit for cyanide and heavy metals. The design included the heap leach pumping and piping, inclusive of ILS, BLS and PLS lines and pumps, and a new booster station for the upper lifts. Como Engineers and PT Como Engineers were responsible for all aspects of the design of the wet plant works, including concrete works, equipment, electrical and instrumentation, automation, structural, mechanical and piping.
